RE: Stripped Out Carb Insulator Block?
Way back when the factory responded to my correspondence, I used to oirder the engines with genuine Walbro carbs - I was charged $25 more per engine to get this "modification" for my engines I think you may have also just discovered why I did that There are a few sellers of engines that advertise "Walbro" as the carb that is fitted - many of the engines have got EMAS - there is a rumor that EMAS is a joint venture with walbro (I do not know if it is true or not) but there is a definite difference in the "primability" of the two brands. (If you bought your engine from a dealer who has adverised Walbro and supplied another brand of carb - send the engine back for a full refund - it's false advertising) SDC80 and WJ71 are both good choices - if you know anyone with pretty much any 100 laying around, see if you can borrow their carb - there are a lot of choices that will work fine on that engine.

RE: AEROVATE, AERO, & RCGF
Ok - Onto part two I understand that due to the association of the Aerovate Engines name with the RCGF product, Henry is about to stop using the Aerovate name and I am guessing that others will continue to use it (This is my surmising - I am not speaking on Henry's behalf here). The new business name for Henry is RC Aero Products - hence the RC Aero name. I continue to use the original brand names - JC engines for the imported units and YD-A engines (YD Australia - thanks for Asking) for my own brand. Here is a commonly used business & Sales model that some cultures like to use Get a product out (Even if you have to copy something) and find someone who has the enthusiasm to promote it from the ground floor. Let the new "Official Distributor" buy a limited quantity (usually an MOQ of $1000 or an MOQ of 50 units - these seem to be the magical numbers - another source of humor in the background). They will then give some away to fliers, sell some at cost and use some themselves - heck, they may even sell some at a profit if they bought enough for that first order. Those first orders are usually hand picked product and because it is a first order - a limited amount can be purchased. Once the "official distributor" is running low on product, the next order is encouraged to be larger (MOQ 50 but they can be squeezed down to 20 for a small marketplace like Australia - but only for the second order). - Ok -this isn't such a big deal - those first 10 products left the shelf in a week or so - so 50 should only be a months worth - right? ("No" is the correct answer). Now some of the second order are not such great quality and some customers will ask technical questions, others will send product back for warranty, others will demand refunds - but a few wil accept what they got - it is cheap product after all (remember the enthusiastic distributor - they probably did an introductory special to get the engines moving and accepted - but still with no support from the factory - they got their full price for everything so far). Ok - now it is time for the 3rd order (MOQ 50) but there have been many changes suggested along the way to improve the product - all this is from field feedback. SO the next order is Version 2 of the engine. (This means another set of spares to be carried). By now some others have noticed the brand and because of the great service given by the enthusiastic "official distributor" the brand name is taken as one worth gambling on. So others jump aboard - al they need to do is advertise (E-bay is a good place - cheap, available and the brand name etc shows up on internet searches) and make sales - heck, they can even refer warranty issues back to the original "official distributor" who will do their best to help in order to help the customers out - the factory is still getting full price for the engines though and have never heard of the issues being experienced. becaus eit is cheaper to just fix the product than it is to send it back to the factory - the "official distributor" just takes the hit. Eventually, the original "Official Distributor" is so swamped that he asks the factory for help - they give him the run around and ignore his correspondence - then they find another enthusiastic person to take on the brand and start the cyclle again. Meanwhile - the Original "Official Authorised distributor" is left wiht remaining stock that he can not sel because of the risk of not being able to service the product later down the track. Ok - here is the next part of the equation. The factory is actually owned AND directed by a person who is known to be "a little shonky". He in fact has another well known brand name that is synonymous with garbage (it is why the new name got created in the first place after all). SO he sells the older models and some of the newer prototypes through that brand - but what the customer gets is a product that turns up in the packaging etc of the main "current" brand name - this further gives the "official distributors" a headache as those engines are often substandard and require more than the usual servicing under warranty. So here is todays quiz question What do the letters HHFTLGRPRORCGF all have in common? Now then - the YD-A, YD Models and RCAero model is better than that - this is ours Design our own product - using off the shelf components if appropriate to do so (Carbs, Ignitions etc) Prototype them and improve them - in house with maybe one or two other fliers towards the end of the prototyping. Make the first production run of the final product Distribute them If there is any sort of unforeseen problem - recall the product, refund money as required and fix the issue. (we did this with the 112 when the reed block issue raised its head). When the issue is resolved - at the manufacturers cost - reissue the product. We don't play games with distributors, We don't play one off against the other and we remain 100% committed to providing the end users with the best possible experience that we can provide. Until such time as he decides he doesn't want to play any more (and I am older than him so he wil probably outlast me in the game) Henry will remain the SOLE North American distributor for YD-A Engines - if these engines appear in a dealer anywhere - they will be from one of two sources - Either through Henry or a copy (We have ways to tell that though and I don't expect it to happen any time soon). Now I wonder why someone would join and make their first two posts on that very same day - right on this thread ??????? (whoever you are eiganvalue)

RE: AEROVATE, AERO, & RCGF
Ok - Time to clarify the situation (yet again). - Sorry if this is a little long. The original engines that Henry and I purchased (as entirely seperate entities) were RCGF engines. At that time, the company was a young compnay that had previoulsy done some industrial conversions for another brand (The Peak 45cc and 65cc side carb engines). They were just about to release their 50cc rear carb. We oth jumped on board at about the same time and bought the engies to our respective markets because they showed an attitude of "we will listen and improve the engines according to suggestions form distributors from around the world". That made them quite unique in the marketplace at that time. We got the engines accepted (At great financial cost to us as all advertising, promotional materials - including engines - and service backup was provided by us at our cost). Once the engines got accepted in the market place, the range was improved and the performance was improved (largely through suggestion from the distributors of the time - we all used to speak amongst each other in those days and compare notes - there is only one of those original distributors left now - and he is in a pretty unique marketplace indeed)- some others jumped on board. Henry began using the Aerovate name for his purposes to differentiate his engines to the ones bought in by others - it was never hidden that they were RCGF engines and no attempts were ever made to do so. Ok - over the ensuing next few years - we were servicing and warrantying the engines at our cost with little to no help from the factory ("For we never heard of that before" - was the usual catch cry from the factory at the time - it was quite a joke amongst some of us distributors for a while - until the joke wore thin). By late in 2008 - the quality of the RCGF product and backup had deteriorated to a point that we decided to look at other options. JC Engines became my second supplier (Area 51, Area 102). As there was still a limited range of sizes available to us, Henry and I colluded on a new engine lineup where WE did the manufacture under OUR control. Seeing as I already had a 5 axis machining centre, CNC lathe, Precision Grinder etc in West Australia - it was agreed that the new engines would be made there at first - then as sales increased to an acceptable point - Henry would set up a manufacturing line in North America. The YD-A engines were borne from that decision (56cc and 112cc twin were the first models). Those engines were released to the market just a few weeks ago. When I took on the JC engines distributorship - the relationship between the RCGF factory and myself cooled - In fact the RCGF factory refused to sell me spare parts. I was left with tearing complete engines down to provide spares for the warranty returns (of which there was plenty). I did this in order to keep my customers satisfied. Luckily, most of the parts that are regularly broken in the engines are either simple to make (such as the prop hubs) or are off the shelf from industrial enignes (Such as rings, cylinders, pistons and cranks). So I can still keep a supply of quality parts up to my customers - but only my customers. Since March this year- the RCGF factory has completely refused to even acknowledge my e-mails etc. Now - Henry has got 3 sources of supply - RCGF for a couple of the better models, JC Engines for a far superior option on the "26cc range" with the JC 28cc and YD-A for the 56 and 112cc. YD-A has also got a lot of other sizes coming soon - all with unique designs and high power to weight ratios - that is what I have been doing recently - the prototyping of those. How that can ever be misconstrued as hiding a fact is beyond me. Now then - if anyone wants to get hold of any RCGF product - I still have plenty left on the shelf here. All is available at my cost plus transport. And the factory has made it very clear that they will cover the warranty direct on their product - these are all serial numbered and I can show certification that they were purchased direct from the factory.

RE: AEROVATE, AERO, & RCGF
Ok - Antique and Cajun1 I absolutley agree 100% with both of you don't get me wrong - as a 15cc gasser, it is fine. but compared to a similar capacity glow - I am not convinced of the general effectiveness of it. HOWEVER - if doing the unusual is your thing - then this is a hobby that we all do for fun - I say go with whatever turns your crank - I wont judge you [:)] Cajun1 There is a very good reason that the 15, 20 and 26 weight similar amounts - there are some things that you just can't lighten (much) Walbro carbs, RCExcel ignitions, Prop hubs to suit the magnets, mounts etc - all are very similar in mass between the three engines. There is also most likely a good reason that most (RC) Gas engine manufacturers don't make smaller than 20 or 26 (In fact - the RCGF 20 is closer to 23cc if you do the math). I am guessing that most dont do it because the power to weight ratio just doesn't work out. Ok - the argument is that you can use a smaller fuel tank - but in that size of plane - is it going to outweigh the battery, Ignition, extra switch etc? - I am guessing not. Antique I have experience with both engines and you absolutley hit the nail on the head.

RE: AEROVATE, AERO, & RCGF
Just remember - the current version 15cc is about the equivalent in power to a mid to low range 0.50 - 0.60 glow. 13/7 - 13/8 prop sizes at 8000 - 8500 rpm. I am currently testing a 15cc (I still dabble with rcgf - I just don't use the aerovate name for them) and it would be a reasonable fit (powerwise) for a 46 sized glow plane. As Henry pointed out - we get engines from 3 sources. RCGF (to our specs), JC Engines and YD-A (Oh yes- that would be me).

RE: Aerovate Engines
Woo Hoo I had a win at the field today - a guy offered me not one but TWO US 1.20 Lites - NIB untouched. Very very soon, I will have one with one of these 28's in it I was introduced to the Stick when I was in the USA a few years ago - at the field I flew at there was a couple of the US's top Pattern guys. They used them to test bits and pieces out before they put them into their Patern planes. I watched one of the guys put a US 1.20 lite through his unlimited pattern routine - from that day onwards, I have always had one in the hangar - can't wait for someone to get them back in stock here - I tend to do silly things with them and break them regularly. Having played some more this weekend with the new 28's. I must admit I am pretty impressed with them. this is probably one of the nicest engines I have seen from this particular manufacturer - and they have been known to make some pretty nice engines in the past.

RE: Aerovate NEW Twin-YD/A 112
Yep - I decided to get a few local flyers as the test pilots and since the issue with Bobs and your engines cropped up have refused to supply the 112 to anyone other than my local flyers until I get good repeatable results similar to how the prototypes performed (In the air as well as on the stand) - that includes the initial prototype production run. This is why you are seeing very little posted - we took most of the 112's back for investigation and those that have got them have agreed to keep in contact with us while we get the issue investigated. Those that have waited patiently for the past nearly 3 weeks since this cropped up - you will get a new 112 back with the updates - I am pretty sure you will be much happier with it. The problem is pretty much sorted out now. The reason for the lower RPM's on a small number of the engines seems to be from a couple of sources. The main one being an inconsistency in an "Off the shelf item" - the reed block. We use a common reed block but have noticed differences between them. Part of our in house QC now includes a jig measurement of every block. There is also a tendency for fuel puddling if either needle is set rich. In a couple of cases, the customers mentioned that they had one of the needles set at 6 turns out. This is self defeating and I will explain why. Due to the location of the fuel pulse pickup point, a rich needle will allow fuel to puddle at the base of the reed block (the reeds open from the top first). As this puddle increases, the fuel pulse line gets covered and stops the diaphragm pump working. This gives a sensation of leanness so the natural reaction is to open the needle further - then the cycle starts again. This is also shown up when the plane gets inverted - the fuel puddle then dumps into the crankcase and the engine runs pretty rough for a while We are relocating the fuel pulse pickup to an area where this effect won't cause that problem. We are currently confirming a new production (in house) reed block that negates the puddling issue in the first place. I have manually modified a few of them for experimental purposes but those modifications are not long term fixes. Once the production reed blocks are proven (and that can only be done by a lot of flying hours on each engine) we will be ready to re-release the engines. We are now very close to being ready to re-release the product and those that have chosen to retain their engines will be getting all updates done. Even those that are flying with good numbers. We do appreciate those that have stuck with us over the past 3 weeks since this raised its head. We have been working pretty much flat out on the issue during that time.

RE: Update on my CRRC 26, PROBLEMS please help
Some gas engines don't feel like they have much compression when N.I.B. Especially the smaller Gassers. As Charley mentioned - reset the needles - 1 1/2 turns out on each should get it running. It is also possible that it is simply flooded - take out the plug, blow it dry and reinstall it, then make sure the cap is on tight - Most caps are real hard to put on - make sure it is fully over the plug hex. you might be surprised at how much force it takes to get it on tight. (do not twist it on the plug - EVER - you can easily damage the silicon boot by doing that). Make sure the ignition battery is properly charged (If it is an RCExcel ignition - use a 4 cell NiMh or NiCd pack - NOT a 5 cell) Then Throttle to low setting - open 2 or 3clicks on the trim - definitley no more than 1/4 open Choke on Ignition on Flip it until it "pops" - it wont run Then Choke off Flip it again and it will run If it pops but won't run - do as Charley mentioned - use a starter

RE: Aerovate Engines
You will find that as long as you perform the right heat cycling to run it in, the power will increase quite a lot. These cylinders have an electroplated chrome liner (not the lower cost flame plating that some others use). This is a a very tough material and takes a little longer to polish up completely. The Ring is also a molybdenum steel alloy, This is also for toughness. The upshot of that is - they need to heat cycle to run in and run in can take a little while. This is something that many modellers have forgotten about with the raft of engines out there that use softer materials so that the gratification comes quicker (so does the wear rate unfortunatley). The heat cycling is best done by doing what we do best - run a tank or so on the ground, tune it (but not too rich - that will just make it run poorly and slow the run in). then go fly it and avoid "no airflow runs" for a little while. I tune to peak RPM minus 200 - 300 rpm rich after about a litre of fuel and run there for the first gallon or so after that.

RE: Aerovate NEW Twin-YD/A 112
We ain't saying much right now because our mothers taught us manners - such as "Don't speak unless you have something useful to say". The YD-A's aren't the only brand of engines to have had a small percentage of problems early in the peace. - ARE THEY?. We are currently working through the problems and are sorting out solutions - all customers have been contacted and the overall support for us is strong. Yes - there are a couple of 112cc engines out there that have presented problems - but we are working through them as we speak and we are working with our customers to ensure they are not suffering from the problems. coverage is 100% by Aerovate dealers - not at the customers expense. Just remember - these particular engines came about because of a major failure by some other brands to achieve what the flying public want - cheap reliable and consistent engines - We have achieved it with the 56 - we have identified the problem with the 112 (we think - but we are currently verifying it) and we are correcting the issue. For those (not necessarily posting here) that wish to sling mud - feel free to go ahead - it washes off eventually and fortunatley you are in the minority. For those of you that have given support to us (the behind the scenes suport is what keeps me in the hobby - if it wan't for that, I would have walked away many dollars ago) - a big thank you and you can look forward to a very bright future.

RE: RCGF Engines
[quote]ORIGINAL: AJsToyz Johny B is just stating its not made at his factory. Andy [/quote] That is right - as Catherine quite corerctly stated, the 28cc is not an RCGF manufacture - it is a JC engine. There are 3 sources of engines sold under the Aerovate name. RCGF make some models, JC make some and YD-A make some. All are very different manufacturers and very different models. The JC 28cc uses the same off the shelf cylinder that RCGF originally used for their 26cc (Now RCGF use a different one but the critical measurements are identical - just the side plate is not there). The crankcase is also very similar but the crank is different. The outward appearance may be why some are confused as to the manufacture but the manufacturers name is pretty clear on the box and the engine itself. I know that neither Henry nor I are ducking from the engines, what we are doing is working with the manufacturer to try to find out why it is that some of the engines are performing flawlessly and others are not. At the same time we have recommended some changes be made to them to bring them up to spec. These are similar issues that caused us to depart from another brand recently and are the reason that I instigated a thorough set of inhouse partial disassembly and checks on every single engine prior to shipping. It is also the reason that a new Western built brand came about - simple QC.

[/quote] Gee - I have spent all day today making the doors in my house wider - My head couldn't get through them last night so I had to stay here in my office [:D] Henry and I have had many discussions on what we want to achieve - one thing we have totally agreed upon, right from the day we first met, is that we should always strive for consistency in quality as well as the best possible product we can provide - all aimed at what the end users want. We both come from very competitive Engineering backgrounds- Automotive, Aerospace, Petroleum service and Product development - we totally recognise the need for listening to the customers. This is what makes some engine companies very successful in this hobby of ours - and what lets many others down.

RE: aerovate 52cc twin
Hi I'm not all that familiar with the model (GP 1/3 Pitts) but from what I have heard, the 50 twin will be ok for it - not fantastic but ok - a more powerful 50 Single might be a better choice (Maybe a YD-A Aerovate 56 - also available from Piston)

RE: aerovate 52cc twin
The Aerovate 52 Twin is made for us Aerovate dealers by RCGF. It is probably the best engine that RCGF make and is pretty much the only RCGF engine that I now keep in stock. Yes - it is not as powerful as most of the 50cc class singles (very few twins are as powerful in raw brute power as their equivalent displacement single cylinder counterparts) but it is a smooth running engine. There are other variants of it on the market such as the GRPro line (made in the same factory) but the most recent pictures I have seen of that one has a different cylinder on it.. I still fly one occassionally in a Kangke Texas Hurricane -it fits neatly inside the cowl and will happily power that plane through the Basic, Sportsman and Intermediate IMAC sequences. It doesn't have ballistic vertical pullout from a hover but it will hover the plane. Make sure that whoever you purchase from over there has a great after sales service record. For my money, Henry (Piston here on RCU) at zrcgf.com is the best over there for service.

RE: Aerovate NEW Twin-YD/A 112
Hey mate - no offense taken. I just figured it was time to pass on some info because I have had quite a few asking. I didn't get the e-mail but Australia is a big place - it could be in a red jacket on a kangaroo somewhere. As for how similar things look? - always an interesting question There are certain design restrictions for engines that are accepted readily into this hobby. How many tiomes do we hear "That is a copy of XXXXX brand" - sometimes it is, other times it isn't We have a "bottom feeder" for the carb inlet to the crankcase (as do many other brands) We use Walbro, RCExcel and NSK (as do many other brands) There are a couple of other very minor "off the shelf" parts that are also used but these will change as the economy of scale dictates. Our crankcase is a genuine design of our own but the inlet area has to fit the Walbro products that bolt onto it The general dimensions are similar to other brands - because that is what is required to fit easily into most ARF's (sorry - we cant quite get the same bolt pattern as a DA100 on the mounting plate due to the crankcase volume - but it is close). The cylinders have that unique rugged "Outback Aussie" look (A phrase that was coined to me tonight by someone). But the real tricky one for us to overcome? OUR metal with the Chemical Symbol of "Al" has an extra "I" in it's name - this is a hangover from our colonial past - it is pronounced "AluminIum" here. (But it is still mined here in West Australia by Alcoa - the ALuminium Company Of America I believe is the original name). Try as I might - I just can't get that changed here [:D]

RE: what happend here???
Which carb is fitted to it? Some of that brand had the 645 - others had the 785 I noticed a similar thing in some of the 645 fitted ones but I attributed it at the time to them being run on 25:1 Mineral oil

RE: Aerovate NEW Twin-YD/A 112
Hey Andreas - you are WAAAAAYYYYYY off the mark - you will see that when you put the two side by side [;)] Pat If they haven't done so already - your parts should be walking throught the door about right now. Ok - "YD-A" as it is written on the engines and is the registered name of the brand comes form the manufacturers name - here is the explanation YD Models Australia YD is named after my two sons "nicknames" from when they were young - "Yahdie" and "Dao" - this is what they called each other because they couldn't pronounce each others names properly. Those names still stick to them even though they are now in their late teens. The engines came along because of the other two brands that are alluded to in earlier posts 1 brand started out good, then the "Marketing department" of that brand did some weird things at the same time as their consistency changed. I found another brand (after a suggestion from a guy I know who also sold both of those original brands at the time) but that brand didn't quite live up to expectations either. Henry and I got together and decided that if we were to control product quality and consistency, We had to do it ourselves and be very specific about any parts that were not made 100% in house (Yes - we do farm out some items, such as pressure castings, bearings, Ignitions and Carburettors and raw forgings however WE own the dies and molds for the castings and forgings - we are not the only western company to do this). I looked around and very nearly purchased an exisitng manufacturer but that purchase fell through at the last minute. It just so happened that I had used my time in China well and had purchased some new equipment for my factory only a few months prior to us deciding to do this. (5 axis CNC machining Centre, CNC Lathe, Precision Grinder, Universal Mill and a few other bits and pieces to go with them) Because I had the machinery, it was agreed that we would use that until the time was right to set up a second manufacturing facility (That decision is based upon economies of scale of course). What the result is is the first 2 models being released - the 56cc and the 112cc. Coming soon are some others - I wonder what brand people will "assume" those are. As for my standard answer to when people joke about "Why DA" - I can only say this Why not indeed? - That brand are great engines with a great reputation for customer support - we intend to have the same or better reputations with the YD-A engines. And that is the reason we decided to incorporate the excellent feedback given to us and delayed the mass release while we incorporated it all. (and I am sure we are neither the first or the last of the quality brands of engine to make such a decision).
