Been working on an old Aerotech Hellcat kit I got from a friend. She was about 50% when I got her, been putterin' with it and got it ready for hinging and covering. No radio or motor yet, I'm thinking about an OS 46 for power. I'm wondering if anyones done one, and if so, hows she fly? Shes got such a short tail movement on her I'm concerned about flight characteristics. Is she stable or squirrelly? Should I add flaps? Any imput would be greatly appreciated. Thanks guys...
