I am in the throws of building a Dykes Delta. It calls for a 15 size 2 cycle engine. I would like to convert this to electric.

Question: what size motor should I use (with gearbox if necessary) to power this plane with some authority? I don't want something that will fly just above stall but fast enough for aerobatics.

Is there some chart somewhere that give the electric equivalent of fuel engines?

Thanks, Phil
