Addendum to my last post. DO NOT be concerned with counter rotating props on the electric versions. It doesn't effect flight one way or the other. I am using standard electric 13x10s on my B-26 and 90 inch NITRO P-38. Do not notice any torque effect. Of course I do not worry about engine out problems either!! Four flights on the B-26 and about two dozen on the P-38. The 38 IS more aerobatic then the 26. We put a movie camera on the horizontal tail of the 38 last fall and you can go to ''tire fire'' on you tube and take a ride on the 38 under Don Morse P-38.
And you won't notice the difference with glow/gas either, engine out or not. CR props are a solution to a problem that never existed in the first place.
