I think I'll go with same thing I have on U-Can-Do hitec 635's. They seem to be working ok but I have them on 6V. As Minnflyer said she's not a wild bird so putting around is what I'll be doing. It's been hard to get much info on this plane, but I like having planes no one else has at the field. The U-Can is ugly, so I'm only one has it at our field, but fly's like a dream slow and easy, my thumbs can keep up. I hope this girl will do the same.
