still putting the plane together the instructions are horrible, the motor runs very reliable when in the mustang, i wrecked it doing a spin and when i tried to recover i pulled up to hard and stalled it sending it straight into the ground, so i figured it was time to try a acrobatic plane i am a little nervous that it will be to unstable. but you have to start somewhere. i do have a question about the mounting of the motor, i was planing on mounting it upside down and centering it on the fuse, is this the right way, and if so the muffler is going to be a tight fit, so do i turn the motor or do i get an extension for the exhaust. also any advice on how to cut the cowling,
