Glad to read this.
The next project is a Rascal 110 , which requires cutting up the fuselage to internally mount the ignition.
Having a glowplug w/ a gas really simplifies the power system. Im thinking a glow plug igniter wired for low throttle may control lower idle rpm's and these are still easier to mount than an ignition box with less interference to RX. Ive got the plane, time to order the engine and GG plugs!
gives this doesn't really have a good think
