RE: B-36
it would be helpful to know the make and type motor weather 6 volt 7.2 volt 8.4 volt or 9.6 volt?still think brushless motors capable of spinning 8-6 3 blades at 10,000 rpm with li-po batteries are the way to go.i know you gave me no load specs on the motor you were going to use but what is the rpm with a 9-6 2 blade or 8-6 3 blade prop need 10,000 rpm.batteries could be placed above the wing oe/and below,the gun bubbles could be made scoops or left open to allow air to enter and exit to cool the batteries in flight.
