2+ years on,,,
My Rcgf 15cc is still going strong although I have had 2 ( on this and my 20cc rcgf ) hk ignition boxes go on me and a new Rexel also which would give the proper RPM readings it did make the engine splutter in mid range and give my servos the gitters,, so now the rpm counter is unplugged all is well, 'however', due to the 20cc vibrations ( treated on rcgroups) I would not buy another 20cc Rcgf engine, I bought a DLE 20Ra, ok its double the price, but it's worth it.
