Status: offline 		Anyone know how to size electric motors for a twin engine plane? I have an old kit without instructions that says it will weigh out at about 30oz. I've checked all of the moto-calc type software and none seem to have inputs for twins.
I'm thinking it might be overkill to use 2 motors that would handle the full load? It would be for sport flight, not 3D.

If it's anyhelp to ya, I ran the Hobby Lobby B25 on a set of TowerPro 2410-9y motors, 18 amp esc's, spun I think it was 8x6 three bladers on it.
ran it on a single 3S2100 pack. Pulled like 16 or 17 amps combined.
