Hey, thanks for the info. I did see one of your forums awhile ago, but I lost it. I actually did look into the that engine yesterday, and that may be my pick. Can you believe when I contact TF about using a gas engine, they were totally against it. I wanted to stay away from nitro. Nitro costs more, messy, and the four stroke nitro are way too much money. So did you finish your p47, and what type of covering are you using?
