Advice on Twin motor setup plz

       Remove this ad - become a site supporter!
I have a twin. It's designed to run on 2 .40 2 cycle engines. I'm 90% convinced this has to be changed to electric. Problem is, I don't just want to have the motors turn in one direction. For reasons that are to deep to explain here, at this time, I would very much like having the motors to be capable of "reverse thrusting". I don't want to vary the pitch, as it is impractical with this model. I just want to reverse the motor rotation. I'm not needing full thrust, so the inefficiency of doing this is not a concern. Here's what I've come up with so far, I just need some help getting the right sized motors.

The reversing thing I think I've found a solution for. I'm planning on using a rccar ESC with reverse. I see they have them for brushless motors now, so I can stick (I hope) with a brushless setup. I'm not sure if the plane motors have timing though. I have read at the Novak site that in order to reverse the motors, they need to have 0 timing. I have no clue what that means! If someone can tell me if plane motors will work, I'd be forever grateful!

Second problem is the props. This is a semi scale, already framed up airframe and wing. I am not willing to redisign the thing, I just want to repower it. Problem is the nacelles. I have 11" max between the centreline of the nacelle and the fuse. What kind of motor could I install in here, and have a 10-6 or 11-6 3 bladed prop? I think I'll be limited to around 12 volts, as I'm using the car ESC.

Efficency, weight and all those frivolous things, I would like to disregard. I know this plane will not fly for a long time on electric, and it's not going to be a rocket. I think the AUW with the glow setup would come out around 12 or 13 lbs. Less all that, i'm working with an airframe, that will weigh around 9 or 10 lbs, plus the weight of the electrics.

If any of you have any knowledge or educated guesses on how I can accomplish this, I'll be very grateful! I have prowled the net, but when I look at specs my brain goes fuzzy. I have to have a whiff of castor oil to come back to reality. There are so many different motors out there, my brain is a mess! I'm sure if I could be pointed in the right direction, my head can stay clear.

Thanks in advance


ps:I have posted this question before, but all I got for a reply was "built it as per the plans". That is my last resort!
