need a lotta info on installing electrics into my royal b-17. i have 4 new .30 four stroke engines and would really like to preserve this plane as long as possible. have questions about brushed motors versus brushless. and can one speed controller be used instead of four. also which motors will spin 3 bladed props. without spending $12000 it would be nice to walk into a shop and set it on the counter, come back a day later and its electric. i guess its ok to dream in this hobby. any help would be appreciated. i am almost willing to swap the 4-strokes for the electric package.
