instead of a glow driver, you could use a CH-Ignition electronic ignition unit and spark plugs. Runs on 2s Lipo voltage. Much more precise firing of the cylinders, and the engine is not so twitchy as to fuel mixes that you use. $135
Easy build, I made a stainless plate to mount the engine using the original mounting holes in the firewall. No extra weight required to balance it. I installed a glow driver to assist in keeping all cylinders firing. Just replaced the crankshaft bearings. Mine runs on Optimix 20%. I was flying it at Deeside last Sunday.
