This is my 3rd edit of my F-20AV tweaking the roll rate, CG, thrust angle, wing and tail incidense to visual scale and other dynamics to make it fly better. It's still fast although it may appear slow on takeoff and landing because of size. Brakes are on throttle. Usually I'll approach around 80-100mph, takeoff seems best around 75mph. I hope you have fun with this third installment!
