RE: New statement from JC ENGINE power co.,ltd
Ropomond, Thanks for your response on this matter. It's great to see people that take a reasonable approach to this. I would try and tell you why I am doing business with JC again after having been burned. The money lost, I wrote off, that is just one of the perks you have when Importing goods that you have not seen. I have been in this business since 2005 and have seen a few things happen. In Namibia and South Africa hardly anybody flew large scale plans at that time. In 2006 I bought a 50cc plane that I kitted with a "Peak 65cc" engine and flew it. Everybody noticed and wanted one. I made it my mission to supply the RC modeler with LS Planes and engines at a price they could afford. I started out wit CRRC pro 45cc engines that where at the time very troublesome. In the following year I went to my first show to China and although DL Engines was not an exhibitor on the show I found a contact that could supply these engines to me. Great. DL was not well known and only a very few people around the world had dealt with them. I took the chance and ordered some. These engines as we all know by now are good and so my business grew with happy customers. A short while later every Chinese wholesaler had these engines and everybody was selling them with no warranty and no service. In South Africa this is widely accepted until something goes wrong! Once that happens, lets go to the guy that started it all and see if he could help. I got tired of not only that, but also of the price wars fought. In the meantime I sold and still do sell the RCGF witch I am happy with and so are my customers. Coming back to JC engines was simple, Kevin had burned his bridges everywhere and he is aware of that. I thought of giving him a chance and we will see how that turns out. I am now the only guy selling the JC range of engines in South Africa. I do not have to compete with all the other "DLE Dealer" out there and I can concentrate on keeping my customers happy. I am not saying that this is the best thing since sliced bread, nor am I saying that I know I am not going to get burned. All I am saying is that the quality of products that I have received from Kevin in the past months is very good and I am hoping that will stay that way. As for making money, stay in the printing game as you make no money in this game.

RE: New statement from JC ENGINE power co.,ltd
I would like to add something to this discussion. I am one of the guys that where burned by JC's inability to deliver a decent product in the past also. At the time, it was not so much that the product was rubbish, but that the problems this product had where in no way acknowledged by JC and where not rectified. I dropped the JC line of engines and cut my losses. I even bought back most of the engines I had sold to my customers at substantial expense. When Kevin contacted me in October of last year I ignored him at first and only responded to his e-mails once he offered me engines to test at his expense. The devil inside me thought, I will take what I can, if it's free It can't hurt me. The first 60cc engine arrived in a very neatly done up box. Properly packaged with instructions that actually can be read by English speaking people. The engine looked good, well made and well presented. Looked inside, and saw a well made and properly assembled product. Ok I thought, I will run it on a stand and see how long it will last. After about one hour on the stand I was well impressed with the engine, it ran well, it started well, it dose not shake and it has not fallen apart. At the time I was busy building a new Pilot RC Extra 300 that was supposed to get a DLE-55. I opted to try the JC 60cc in the plane instead to see how it would perform in the air. I finally finished the plane in late November and flew it. This simply blew me away. The engine performed flawlessly, running a Menz 23x8 prop with power that I have not experienced with any other 50-60cc class engine. As with the 51, it has a very smooth throttle response that is quicker than most. The plane has now done 341 flights with +- 45 Gallons of 32/1 fuel thru it and has not missed a beat. It's running a Menz 24X8 prop now and pulling the 17.5 pound Extra around like a rag doll. All this at 6800 feet above see level. Kevin's JC 30cc has equally impressed with having more power than a DLE 30 right out the box and running just as flawlessly as the 60cc. I have just mounted the 120cc to a 35% Pilot RC Extra 300 it's done 7 flights and is impressive. Kevin has in the meantime been more than complaint with my requests, and trust me I did push the guy hard. He has kept all his promises in a timely manner. I think the guy has seen the error of his ways in the past, he has come to realize that you can fool some of the people some of the time. In my eyes, he is now delivering a very good product at a very good price and he is standing behind it. I for one being very careful have again started selling his product with very happy customers so far. I will be buying small quantities of engines at a time making sure that each and every one gets checked before deliver to the customer.

RE: 150cc low on Power
Thank for the answer guys. I do agree with RTK about the squish not actually being to small. You have to consider that the engine has no real squish band though. It has a square piston (completely flat top) and the combustion chamber has no combustion dome. Only a very small indent where the plug hides. So in essence, there is no space at all for the combustion gasses. I will give it a try and let you know. Regards Andreas

RE: 150cc low on Power
Hi Guys, I have finally found some time to fiddle with this engine again. I know it's been a long time. I have yesterday measured out the engine and have found the following. The cylinders are hardly domed and neither is the piston. Meaning that the piston will fit exactly into the cylinder right up until the two meet. The squish measured here was 0.8mm's. As far as I am concerned that is much too little. I have then cut new caskets at 0.8mm each and added them so that the cylinder is now raised by 1.6mm. The compression still seams very high, but I am actually able to turn over the engine by hand now. There is only one thing that bothers me now, and that is the piston will now travel a good 2mm below the exhaust port opening before reaching BDC. This might mess up the cross-flow completely. I will only have time to run it the weekend. What do you think?? Regards Andreas

RE: JC 60cc Engine
Hi Guys, I have to bring this up again as some guys here would like to know whats going on. The engine is fitted with a pits Muffler from a CRRC pro 50cc engine. The engine was run on a mix of 32/1 Sthil HP. I have had a JC 60 for some time now and have finally got to fly it yesterday. The engine is installed in a Pilot-rc Extra 300 weighing 7540g fueled (that's about 16,5lbs) It was flown at the Windhoek Radio Flyers field witch is at exactly 2000m above see level. (that's about 6560 feet) at +- 32 degrees Celsius. Engine was fitted with a Menz 24X8 prop for the first couple of flights and I have no Idea what the RPM's are on it with that prop on the plane. It pulls, that's all I can say and it pulls hard. At our altitude there is not much in the 50cc size rage that will pull a 16.5 lbs plane vertically forever, but this thing dose. It ran without any hiccup, not a stumble or a hesitation. I later changed the prop to a Vess 23B witch i think pulls even harder at full throttle with hovering being done at +- half throttle and a very very decent pullout and again unlimited vertical. I do not like this prop, as there is too little bite in the mid range. After about 5-6 flights the engine was torn apart and checked. There are no signs of any running apart from it being oily. Although the compression had greatly improved during the day the ring has a very long way to go to seat properly. I will go on flying the plane, If you don't hear anything, is all good. I will however report back if something happens. All I can say that it pulls harder than a DLE 55 that I have been flying for some time in a 50cc Yak that weighs about the same. If it lasts, this might be a good engine, provided the backup promises can be kept,,,,, witch I have to question due to past experiences.

RE: MY FAVORITE GASOLINE ENGINE
Very surprising that the people that have RCGF and know how to use them seem happy with them. My Favorite engines are: RCGF 100cc starts very easy and runs like a clock (that is when it's getting fuel) RCGF 110cc same as above RCGF 55cc runs like a raped ape And TMM 106 still new, but behaving very well

RE: JC 60cc Engine
OK guys, First run: Started right up with the needles left as they where. High end was way lean, and had to be turned almost an entire turn out. set the lowend as soon as the engine was warm and let it run for +- 10 minutes at 2000RPM just to get it used to it. Nr's that I have seen so far are 6350RPM high end after 12 minutes of running with the high end not set properly. So far nothing has fallen of or broke. I will let it sit at 2-2500RPM for a while and set the high end to top and report back soon. Regards Andreas

RE: JC 60cc Engine
Hi Guys, I have one. I will be strapping it to the test stand and run it tomorrow latest. The engine looks quite nicely made, with everything in the box. It comes with a pitts muffler that is useless because the drop is much to low, it will never fit in any cowl. Upon opening the engine (I only took the reed block of to inspect the crank) as this was JC's biggest problem in the past, I saw a very clear "DL" stamped on the con-rod. I will run a Menz 24x8 on the engine that the factory claims will run 6700RPM. We will see. I will let you know. regards Andreas

DLE-111 strange unevenness
Hi Guys, I just had a call from a client that planted his DLE-111. He said that he took of the cylinders and the one is clean as a whistle and the other one is totally packed up with carbon. I can remember that when he got the engine he had problems with one cylinder missing until the temps came up. At that stage he changed plugs, he tried a new ignition module, and tuned until the cow came home. When next I saw him I tuned the engine properly and the problem went away mostly and the engine always ran well. Now his new plane is here and he want to send the engine to me for a checkup and found this unevenness in carbon of the two cylinders. I wont know until it gets here but would like to ask for some opinions?

RE: aerovate 50 engine
I'm betting that the engine was run hot and the ring is stuck. Take it apart and clean out all the carbon and make sure the ring groove is clean. Add baffling to the engine and make sure that you do not run hot and have fun. I have seen a few that came to me like this.

RE: RCGF 20 - Rear Carb - underpowered..
Glock23, Check the timing on the engine RCGF have become a little conservative with the timing setup and have most engines timed a little late. I have the same engine running a Xoar 16X6 at 9200RPM. It has done many many gallons of fuel though. A very nice prop to run on the little 20cc is a APC 17X8N. wich I have found will give me the most thrust in the mid to high 7000's. Regards Andreas

RE: 150cc low on Power
Thanks guys, I just like to clear some points up here. The engine is not a 3W. It is not retrofitted with an rcexl ignition, but comes with one from the factory. The engine is not very popular as I have found very little info on it on the web. It is however made by one of the most reputable makers in the business. T.O.M. I have checked the Crank alignment when I first got the engine. Then I got it, there was a muffler bolt broken of in the Jug. I had to take the engine apart to get that out. While it was apart, everything was checked to ensure that it is perfect. Steve, very good point on the magnet size. That problem can cause some headache.

RE: 150cc low on Power
T.O.M. How far do you think I should go with the timing? Alternatively I could just lift the Cylinders between 0.8 and 1.6mm. I was planning on doing that anyway but work has got the better of me unfortunately and I will not have the time in the next couple of weeks. It just bugs me, as I am using 95 octane fuel and have set the timing so far back and this thing still bites?

150cc low on Power
Maybe you guys can help me out here a little. I have a 150cc Twin engine (famous Brand Name) That is a low on power. It will swing a 30X10 MenzS @ 5500rpm and a 32x10 MenzS @ 4900rpm. At the moment I fly with a MenzS 28X10 because it gives me the best performance @ +- 6000rpm. The engine is not new, and the previous owner had some stuff done to it, that I have no idea about. It runs well and starts easy. (when you can get it past the kick) The strange thing is that I find that it has very very high compression. You can not turn this engine over by hand without a prop on it. Also the timing is set to 28 degrees and it kick's back quite badly when starting. I have retarded the timing as far as the slits in the mount will go, +- 5-6* and it still kicks back. While flying I can not notice any detonation by ear, it has however already broken a 6 prop bolts when last I took it to the coast. (I am at 6800 feet above see level) Could it be that the engine had it's Jugs cut down for more compression that is actually hurting performance? Should I try and lower the compression by putting some Gaskets under the Jug to see if I can actually gain some performance? This is just something that came to mind. The engine is running std mufflers, 95 octane unleaded mixed 32/1 Stihl Hp oil. Temp while running are always on the high side of the green. Guys like Pe and T.O.M will probably know about this sort of thing.

RE: Is this a SV-26cc
This engine is defiantly not a RCGF. It is very similar, but not the same. The cylinder was used by both companies and that is where the similarities end. Even here are some minor differences on the plug seat. The Crankcase although again very similar is not the same. The bearings used are not the same. The prob hub is not even remotely the same and the crank, when you ever get a look at it, is not of the same quality (although it has the same dimensions as the RCGF). The ignition is not the same. The engine runs quite nicely. Check the timing, and ditch the ignition and fit a RcExl
