Thanks for the replies,
Im not so much interested in fast flight although it would be nice but rather something that will fly. I dont have an active plane right know as my four-star took a 70mph nose dive into the ground, so i wanted to build a plane i could fly for now. The only engine i have that i know (pretty sure) will work is a .40la. Im not in the mood to spend to much money so im not willing to buy another engine. Do you think that the engine will really be too powerful for the plane? The .40la doesnt seem to be that much more powerful then the .25sf. Also which prop would make it fly the best?
another thing is winter is coming so ill probably be putting three skies on it so it will have some more added drag

anyways thanks alot
