Now for that Cox engine, I am not really sure if the ball and socket would hold out on my standard 10:1 fuel/oil mix, but other than that, I am 100% positive that with a Runtronic ignition I can build something flyable, RC, with that engine. Not even really going to be a challenge. Won't be an exiting hotrodder, just a nice sport plane, but still, 100% sure it WILL fly as long as the engine doesn't wear out
But it will need something different than just a Norvel style glow plug adapter because the spark plug will really mess up the shape of the combustion chamber big time and that will kill a lot of power. Would not be surprised if that would need a custom made sparkplug,

The FP10 however, as you can see, runs fairly well, and that is still without the solenoid.
