Converting Midwest Aerostar 40 to electric.
Hello guys, I have a Midwest Aerostar 40 trainer that had a nitro engine in it, now I have the engine out and ready to convert it over to an electric plane. I was curious if you guys could help me in what brushless motor, speed control and lipo battery would be a good setup to have for this plane? I'm not wanting to set any speed records, but would like something with some good kick to it.
I was also wondering if they made a motor mount that i could buy that would work ok?
Any help would be appreciated, as I would just like to get the right setup going and get to flying this thing. Thanks

I converted a Midwest .40 Aerostar built in the early 90's a few years ago with this setup:
E-flite Power 32 (or any other .32 770kv ish motor)
60A ESC with at least a 3A UBEC
12X6E APC prop
4S 4000-5000mah LiPo
I would get this motor (cheapest one) - http://www.headsuprc.com/servlet/the...2-Sport/Detail
I built my own motor mount of nylon spacers, blind nuts and bolts. You could also hack off the side panels ahead of the firewall and simply bolt the motor on from there.
I had enough power to go vertical all day but it was still lighter then the glow setup. I towed gliders with it and flew off water and snow before I finally wrecked one final time Have fun!
BTW- keep the rubber bands fresh or this might happen:

Gruesome looking crash!! I have had a wing or two come loose in my time and I always find it interesting that no matter how much up elevator you give it does not seem to help . Worst part I would imagine was the LiPo. Looks fairly bent up.
Good to see that the plane is being rebuilt. I always advise anyone who has a bad crash to pick up all the pieces and they let it sit for a few days. The damage always seems worse right after it happens and after siting for a bit a repair job looks more doable.

Just curious, how many rubber bands were you using when they failed? I usually put about 12 on my trainer... probably would help to have a little more redundancy, it looked like there were only 4 on there.

WAGliderGuy has pretty much exactly what I was going to suggest. I would only recomend a 13x5 prop just to keep the airspeed on the trainer down to something reasonable.
The guy with the 12x10 on the trainer... YIKES!
You gonna go fast!
