You know, it's funny you say that. I also tried it and the weird thing is that is was not consistent. You could hear it arcing somewhere, but not to the boot. If I can get that king of spark to the plug, then I'm sure I would have no problem. Also, at least yours ran!!! If I don't have the six volt, then it won't even try to fire up. That is an indication of a spark issue. Thanks for the reply...

Before the fix it would do the same thing yours is doing, I put 6v on it and it would run, but it wasn't great. I thought it was the switch also, tried a new one and still no good. It was the boot insulator all along.

RE: RCGF Engines
Henry, now I'm really frustrated... I went to my LHS & spoke with the owner. I actually went to see if they sold an ignition unit. He lookes at it, said that probably wasn't the problem, but that supposedly there was a batch of engines that had an improper timing issue??? That just left me lost. I think he was kinda upset cause he said I should have bought it from him in the first place. So at any rate, go to second hobbyshop, and the dude told me he didn't really know too much about electronic ignitions... He said to try and keep it running with another 5-cell pack. So I purchased ANOTHER 6.0v 1400 Mah batt, charged it and tried again. Now it ran for about ten seconds, then quit... It popped a couple of times, and just does not want to start. I tried my original battery, and nothing. I ended up hacking the boot cover, to see if there was a split somewhere cause I can hear it arcing sometimes, and no spark. Well, needless to say, I took the whole thing off the plane and it is all boxed up. I don't mind paying for a new ignition module if mine doesn't work. (after hack), but it still shows the same weak spark. (not consistently) Can you please help me and point me in the right direction. I waited forever (shipping issues) to get this thing, and I still can't enjoy it. Very frustrating. If you can help me out somehow, I would greatly appreciate it. At least get me in the right direction. Thanks

Hi Irish
Don"t know about running at the factory, but all I can say is both needles were in maybe 1/8 of a turn to down tight, But at this point I don't have a problem as this little engine is a little power house that I think will fly my old dragon lady like it nevwr flew with a G-23. Then on to a new bipe barf at about 9 to 12 lbs.
But I do plan on posting more as I go along

RE: RCGF Engines
Hi, just received my new 26 rear carb, question, Is it okay to make standoffs 3.5 long ? It is going in a Cessna 182. I can make them out of 1/2 x 1/2 Maple or I have a Lathe and can turn them out of 3/4 Aluminum round stock.

These are the standoffs for my RCGF-62. The small standoff is the one I got with the engine.
I think if you have a way to make it then aluminum makes a stronger and cleaner setup.

RE: RCGF Engines
The maple would let you box in your standoff and absorb the vibes from the engine better. I have had both setups on the same 26cc engine on the same plane just to check out the difference in vibes on my Ultimate BI-Plane and I think the maple standoff works better for longer needed standoffs. Just my two cents worth.

RE: RCGF Engines
i will be using 4" PSP aluminum standoffs for my RCGF 62cc. PSP doesn't make 4" so im stacking 2 2" standoffs on each leg.
and ordered 4 5" socket head cap screws and they are barely long enough. im hoping that the 1/4" ply firewall will be adequate.

Is it because of the wood dampens the vibration better ?

Aluminium stand offs look very nice but using wood is much better.

Travis, All-thread works pretty good. I use 10-32 and red locktite a nut behind the firewall. Then red locktite a nut on the outside of the firewall (appropriate washers included to spread the load). Then stack the standoffs, I've used wood and aluminum, both work. Then blue locktite the finish nut or use locknuts.

RE: RCGF Engines
Ok I thought I might get to fly my 26 to day but to much wind gust 5 to 30 and cross wind, So I just put some more run time on it.
About 45 min, so now about a total of 1 hour 10 min or so, any way smooth idle 1850 +/- 20 gained a bit on the top end to 8220 +/- 10. still abit rich but good solid runs, running the stock muffler. one thing at about 4500 to 5000 it has a sharp exaust rap and alittle shake compaired to the rest of the RPM range
now if the weather will just calm down we will fly this thing.

RE: RCGF Engines
I got back out to the field today to fly the Christen Eagle some more with the 50cc Twin. Had three great flights with the engine performing fantastic in all regards. Total full burned so far is just a few ounces less than one gallon.
Engine starts two and three were done by hand. Choke on, three flips of the prop to get a pop, choke off, three more flips for engine start. Simple enough.
Maximum static RPM with the TBM 21x8 prop is 6600 RPM. Getting an acceptable idle down to 1750 RPM, but the best idle is around 1850 RPM. Average fuel consumption is around 1.70 ounces per minute with the power setting mostly around 3/4. The engine exhaust soot seems to be diminishing with every flight. Only a slight trace left after the third flight.
See posts 3008 and 3022 for more detailed information of first engine run and first flight reports with this engine.
I really like this engine. My thanks to Henry and the other distributors for making this a great product!

RE: RCGF Engines
I have the Rcgf 45 and cant seem to get more than 6180rpm out of it on the top end. I'm wondering if running a J-tec muffler with the snufflers is bringing it down. What are some of you getting rpm wise with this engine ? I'm running a Xoar 20x10 for prop. Have tried tuning per manual, setting good transition from low to high first by adjusting low needle then adjusting the high needle for peak rpm.
any help? Thanks, Britt

RE: RCGF Engines
Hey Bubba 9999 I just maidened my 77" Edge today and I'm getting around 6500 on the 45cc running a Xoar 20-8 . The plane came in at 16.5 lbs. The engine will pull it stright up. I think after breakin the rpms might go up some but I am not going to crowd it as of right now. I am running Echo syn oil at 40 to 1 and the engine runs great in any transion from idle at 1800 up. I am using a g-62 pitts wrap around muffler and it is quiet. The engine will idle slower but I did not push my luck on any dead stick today. I changed prop to 20-6 after hard landing and cracked the 20-8 and the engine did run better but like I said it still needs more run time.

RE: RCGF Engines
Thanks FOOPED, at least someone is running similar numbers. I think if I went down to a 20x8 I could probably see 6500. I still only have about 2 tankfulls thru it and I'm running using lawn boy ashless @ 30 to 1. I just thought I saw someone posting numbers in the 7000 to 7200 range with this engine.
P.S. My plane is a giant super sportster right at 16-1/4 pounds, nice to know I might get some good vertical.

RE: RCGF Engines
Yea Bubba I do think you are loading the new engine up alittle fast with the 20-10 prop. I have about half gal at 30 to one Lawnboy and switched to ehco 40 to one. I am not trying to peak the engine out as it is still breaking in and I would have to remove the cowl to do reset the carb. The engine is a keeper, I can see that already just take your time it will turn on more with each flight.

RE: RCGF Engines
Boy thats good numbers . I'm at 2800' how about you. It wo'nt take long for me to finish break in as soon as I get some real wheels on the plane. The foam ones went to shreads on me.
