[quote]ORIGINAL: drac1 I think the engine has to spin at a certain number of rpm before the cdi will fire. (typical of most cdi units these days). Turning over by hand slowly won't be fast enough. But it's good practise not to tun over by hand with the ignition on. [/quote] The cdi will fire if you turn it over by hand, so you should never turn it over with the ignition on.

RE: 1/4 Rutan AMSOil RACER
Hello, I helped build the Rutan Race plane and flew race # 3 for Aimsoil. The airplane had non functional wing struts that were curved to allow for wing flex to calm down the competitions howls of foul. If the airplane had been flown better it would have dominated the class. Flew into the ground at over 200 mph and the pilot survived to wreck more airplanes.

DLE 30 and 20 rear carb
Hi, Can anyone tell me what are Walbro Carb model numbers that can be used on the DLE 20 and 30cc rear carb engines. I have heard that the Walbro carbs perform better than the DLE carb that comes with the engine. Also, do you have any suggestions on where I can purchase them? Thanks Bob

RE: Choice - To much of a good thing!
I am going to try and test ride systems in my hands, on paper they are both great and have positives and negatives, I think holding one wil seal the deal. Thanks carrelh, is this then a traditional style trainer? Maybe I will be best off with the boomerang as itsa marketed as a sports trainer. Redback - same here in the UK, I think its our version of the Avistar, very popular and sporty. Onto engines then! Are there any to steer clear from?

RE: Choice - To much of a good thing!
Thanks again for the wealth of information and thank you for taking your time to pass it on! It is very much appreciated. jester - Absolutely I am still doing reading and trying to understand what all the features are and also when I read about issues they have I then go read about that so slowly building my knowledge. So far I have read both are great - the Hi-Tec has (possible) latency issues and is not compatible with Spektrum (I think this is receivers, no?) The JR is a good deal more expensive and doesn't have features which the Hi-Tec does (touchscreen is real nice) and vice verse it will take a while for me to come to a decision. I didn't mention engines as that was my next item, I was trying to find an Enya (was my first engine and I loved it) but they don't seem to be as popular as before. The thing I would like to know about engines is what to steer clear from, I remember when I was young there were certain manufacturers which lacked quality. Are there the same now? I remember Irvines were not on the same level as Enya/OS. Also there are quite a few new ones which I have no idea about. carellh - Sussex is top of my bookmarks :) The two trainers I have earmarked are the Seagull Boomerang and the Thunder Tiger Trainer MKIII, I know the boomerang is a sport trainer but I'm not sure about the Thuder Tiger, which I prefer (visually and also sentimentally) but I am trying to find info out about the flying characteristics. Also the Pulse XT60 will be my second model, I had one boxed a while ago when I tried to restart the hobby and looked like a fantastic model so will definitely be getting one again! harlanb - thanks for replying, I am visiting a club a week on Monday to talk to the members and get a feel for it, but my gut tells me its home! They do have a trainer but you need to book it out I think, I will get some trial flights on the buddy box before your allowed to join (or at least to assess your capability). I am also going to talk at length to the members about my different alleyways, you also make a very valid point which I have no considered with regards to the buddy boxing and compatible radios, I will need to talk to them about this. Thanks again all for the warm help.

RE: Choice - To much of a good thing!
[quote]ORIGINAL: jester_s1 First off, if you haven't read the sticky at the top of the page that lists trainers, do that. I'll try to make it simple for you though, because this is just how I think of it. You have traditional trainers, sport trainers, and sport planes. If you are working with an instructor any of them will work, especially since you have some flying experience. Basic trainers are the flat bottom, high dihedral jobs that we've been using for decades. The differences between them are fairly minor from what I've seen, with a few being a little lighter and a few being easier to fix, etc. Sport trainers have less dihedral and semi-symmetrical wings. They are better in the wind and fly vertical lines and inverted better at the expense of not being as quick to self-correct. An example is the Hobbico Avistar (the hands down favorite at my windy club). Sport models take it a step further, usually with symmetrical wings and close to neutral handling, but still stall resistant and really good in the wind. The venerable old Ugly Stick is the quintessential sport plane, with the Sig 4 Star a close second. If you want someone to narrow the choices down to you to the best ARF of each class, my answer would be the Sig LT40, the Hobbico Avistar, and the Hangar 9 Super Stick. As for radios, Futaba, Hitec, JR/Spektrum (same company) and Airtronics all make quality units, although if you do some searching you'll find lots of anecdotes of Spektrum equipment having mysterious failures. But they are also the market leader so it could be a simple case of the law of averages. Figure out exactly which Lancaster you'll want to build and how many channels you'll need for it, and pick a radio from any of those 4 that does what you need it to. You also asked about field gear, and frankly it doesn't really matter. A 12/24 volt brushed electric motor with a cone on the front isn't hard to figure out, so get the color you like. I will recommend though going with a battery pack attached to your starter instead of using cords. It makes life easier at the field. [/quote] Carrellh thanks for the information - I was thinking 9 channels is a good point to aim for, providing enough for future but not to much as to break the bank (Aurora 9 or XG8 probably). jester thanks for your reply, gave me a little insight into options. I did look at the links provided on the trainer page but there is no other info so its really providing a list of links to purchase with no supporting info into whether they are good or not and for what reasons. Also alot of the models on that page are not available in the UK or discontinued (I think). Also thanks for the explanation on wings, hopefully any trainer I do look at will have that info attached so I can figure what kind of trainer it is. I did read some info on Spektrum and Hitec with possible issues but any argument has a for and against! I narrowed my choice down to the Aurora 9 and XG8 just from features and general feeling I get from reading reviews and threads. I guess I just need to research a bit into each aspect of the hobby and this will indeed grow and I progress and gain more knowledge. Thanks again.

Choice - To much of a good thing!
Hi all, I am a RC returnee, I flew for a few years when I was younger and am now returning to this wonderful hobby. I am writing this out of confusion and self frustration (both self inflicted). I have looked throughout the forums and picked up great information with regards to starting out (or in my case restarting) but I find choosing just about anything difficult unless I can rate it against something else and read reviews. I have created a list of all the things I will need - from the model, engine and radio to field box and equipment to workshop tools and equipment. I can understand some people may say it better to build up what you need as you need it but I am a sucker for preparation and getting everything I need first time round and hopefully scoring some discount in the process. Second to this I like to buy quality goods which will last rather than cheaper item which need replaced more frequently, I also don't like buying something which I know I will need to replace or upgrade (or even no longer use). In certain instances this is ok e.g. the trainer plane, I know it will serve its purpose and then be cast to the back to make way for new models but for the likes of engines and radio gear they must have use later on. Before picking a club I created a mini points system for location, weather, size, support, training and clubhouse to help me figure out which was one was best on paper, overly anal? maybe but when your time is limited I think you need to make the absolute best of it and best for it. I digress, what I am here for is some help, some guidance from you experienced flyers, builders and enthusiasts. My main gripes is noting the difference between, lets says trainers, how do you decide what is best? I know most trainers are much the same but there are minor difference for example the seagull boomerang states its a sports trainer with a semi symmetrical wing, now compare that to maybe the Thunder Tiger Trainer MKIII or well actually I can't, how do you actually compare them? I see people recommending models but not really describing why they are good? They say there good then they say are all the much the same, I can't quite get my head around that!! Maybe they are just all round good models, I'm not sure as there never seems to be any supporting information. Another more potent example is radio equipment and the one which I am having most issues choosing (well that's a lie, I have only got to item 2 of my list of 50 or so items!). There are so many radios with so many features. I want to buy a good radio which will last me if I decide to build a Lancaster with all the trimmings. Is 9 channel enough or should it be more or even less? (I know this is a bit of how long is a piece of string but there much be a common understanding of this) I have been, on more than one occasion been told buy a DX6i as they're great and serve my needs, but I reply I don't want one as I want to future proof my radio for just about any eventuality. And that's only channels, without then trying to figure out about the different FAST or FHSS systems and all the additional features plus all the new radio manufacturers (and why is my favourite JR so expensive compared to Spektrum??). As I look at my list I see others like starter, what is a good starter and where do I find that kind of information out? I think the answer may simply be write a thread for each item on your list but figure there must be others out there who think like I and have done this themselves! Hope you can help me out on my path to RC enlightenment! :) Rob

RE: video of full scale and RC plane collision
I own a Pitts and they are completely blind to see out of. The spotter was talking to the inbound pilot but failed to evaluate and react correctly. You would have to anticipate the consequences of a go around, I have over 12,000 hours and the Pitts is the only airplane I have had to do a go around because of a blown landing.. The reason the feds punished the Pitts pilot is because he is the only one they can go after, they could care less about who's fault it was. Not the rc pilots fault or the Pitts pilot but a failure on the part of the Spotter.

RE: Current drain using YS170CDi?
I run serperate receiver and ignition batteries on my model and get almost identical run down between the batteries; roughly 100mah per battery per flight. Ignition is slightly less and receiver is slightly more. The batteries are two 1,100Mah LiFe batteries which easily allows for 6 flights + a nice safety barrier. BTW I got my packs from http://www.hangtimes.com/ after some communication with them I was able to get a battery that allows for both charging and balancing through one regular futaba DSC port on the side of the model, very easy for rapid field charging as I don't have to take off the wing to get at a balancer connector. Might be useful for someone...

Has anybody had slight difficulty with the first start of the day with the 170Cdi? What I've noticed is that on the first start it'll run off the prime and then quit, as if it has slight trouble drawing fuel. After a few attempts it will start and from then on it has no problems and runs well. I prime by giving a few squirts of fuel into the carb, and a few seconds spin on the starter before switching on the ignition. Any ideas?

RE: HK GeeBee 1.20 Questions
OK. I will do my best to post what I learn along the way with this one. Dave - When I ordered mine, I did the notify when they get in stock. Went to the site, there were 3 left. So I didn't hesitate. When I completed checkout and clicked back there was 1 left! Haven't decided on electric or gas power yet. Gas would be easier as there is no hatch for quick battery installation - the only access is via the wing saddle. Probably will also use pin hinges instead of the supplied CA hinges. The wings and stab are pre-slotted for CA hinges, but rudder and vert fin are not. It comes with a dummy radial, it doesn't appear to be large enough so I will probably get another - I want to detail the dummy radial with push rod tubes and ignition wire. Think I might try those Robart struts for the GP GeeBee that Chuck suggested as I think I can figure a way to work them in - and ANYTHING I can do to make landings easier, the better. The supplied wire is stout, but just a single wire - no aft bracing or even a coil.

I weighed the parts in the box and with everything minus the engine mount and fuel tank it came to about 8 lbs - 3 oz. I figure an all up weight of about 13 - 13.5 lbs if I go electric or a lb or so less if I go with a DLE 30. If anyone else might know of the manual for the 71" span model, Let me know. - Rob

RE: How weight affects YOUR participation at NATS
[quote]ORIGINAL: burtona But removing the 5Kg requirement at least allows others to compete for less cost if they choose. [/quote] Lately, I think designs appear not to be built to the lightest possible weight for a 2Mx2M plane, but rather they tend to be built as close to the maximum 5kg as possible, with larger fuselages, bigger engines/batteries/bi-planes. Increasing the weight limit will do nothing the change this, and fancy models which are larger/more powerful/heavier will appear, which cost roughly the same if not more than current models. Remember the smaller designs of a few years ago? Although I didn't compete in those days I do seem to remember that they were commonly coming in between 9.5-10.5 pounds. If lighter is always better, why aren't those sized models still not flying? If you want to remove the weight limit, then I think you'll have to cap the engine performance, otherwise the increased weight is a blank cheque to for even more expensive motors/batteries.

RE: So what would you do in this situation?????
My $.02: 1. The man in the straw hat screwed up. It seems he had adequate time to at least kill the engine even if the the crosswind was too strong to taxi in. And the first words should have been "Oh, crap I am sorry - who owns this jet - let me talk to him." Then offer something to make up for it. 2. The Jets were really in a vulnerable place as far as I can see from the picture. There was no fencing to stop errant airplanes. If it were my plane, I wouldn't have it 30 feet from the flight line without any fence between me and other landing airplanes. 3. If you guys were so close to see it happen, why didn't somebody yell or run out and grab the plane by the tail? I know if I saw that coming at my plane, I'd be doing my best to prevent a collision. When I was first learning, I had the plane rolling right at me and couldn't find the throttle cut - I just put my foot out and stopped it by the spinner. At my field, there are some guys that when they are flying, I pull my 100cc airplanes back next to a building and I never take my eye off their planes when in the air. It doesn't sound like this guy was one of "those" pilots, but everyone makes mistakes now and then. As a side note, I race with SCCA in formula continental. If some guy crashes into you - you're both damaged, you each repair your own car. It's racing. If it were any other way, the sport would spontaneously combust into a bonfire of lawsuits and die. At one race, during the pace lap before the green flag dropped, the car in front of me spun off into the gravel, then shot back across the track and hit me hard. The race hadn't even started yet and he had no reason to be going that fast to lose control. I ended up with damage that cost me about $4000 in parts and I repaired it myself. The guy was a blood-sucking lawyer (not that all lawyers are mind you) and could have offered to help me out, but "sorry" was all I got. That's racing. The bottom line in this case, the guy should have offered him SOMETHING and apologized profusely. That's what I would have done if it had been me.
