I am also a distributor for these engines and consider them to be my babies. I did not want to post here, as someone asked for people’s experiences outside of the distributor ring, but now I feel I have to.
The RCGF 26cc engine is a very nice little engine. It's reliable, and makes decent power the best thing is that it is easy to use. The Jug and piston on this engine come from an industrial background (chainsaw/ weedwacker) and are therefore extremely durable, but are not the best performance machines.
The 26cc that I run has now got 7 hours of running on it, this is testing in an endurance plane and when opened, there is no real sign of it having run in.
I started of with a Menz 18X6 at 7200RPM then when this did not produce the speed that I wanted on the plane, I changed to a Menz 17X8 (in my opinion the best prop for this engine) The engine ran a 7600RPM before the flight and after 50 minutes of flying with a hot engine just after landing it had picked up to 7800RPM It has stayed at this Nr. for now.
Now, please consider that I am stuck at 6800 feet above see level, and some 100-300RPM's more are to be expected at lower altitudes.
I for one, would not stack this engine up against an OS 160 FX, the FX is stronger. I have also owned a G26 and it is also stronger, only by a bit, but stronger.
That being said, it is still a very very nice little machine, and a pleasure to work with and at the price, who can argue with that.
