Check with the guys at New Creations Hobby Shop in Willis, Texas.

They are an "All electric Hobby Shop" and should be able to give you the straight talk.

There are a couple other all electric outlets but New Creations is the only one I have bought from. Nice catalog too.

You can go to their web site at:
www.newcreations-rc.com

You can get their phone number there. Someone on another thread said to talk to "Kirk" and he can run you info on "Motocalc". He will need a little more info than you have posted. Will need to know sq in of the wing for one.

The other place you might check would be the online RC Electric Magazine. www.ezonemag.com
Ask you question there and you will get plenty of help.

Good luck.
