Huminski,
I see you have a great brother like I do. My brother gave me a late Christmas present on Saturday, A Hangar 9 Miss America... woo hoo.
Thats going to be an awesome plane when you are done. Keep up the good work. Regarding your motor choice, I've seen one of the new Saito FG20's. Its based on the Saito 125 and I really don't think it will be enough motor for an aerobatic plane like your Extra. IMHO a better choice would be the Saito FG35 which is based on the Saito 220. That motor should be powerfull enough to give the plane awesome performance....
Keep the awesome pictures coming.
