What mods are a must on a classic model 4? Mine is a speedster but the only thing I'm really keeping from the speedster is the flight surfaces. I am adding the bay back into each wing and changing out the landing gear. I've never flown a KF and there's a lot of threads about adverse yaw and lack of authority on flight surfaces.
Do I need to add electric trim?
Lager elevator?
Lager rudder?
I'm pretty close to covering so I want to make any needed changes before. I would love any advice on anything pertaining to building a model 4
Thanks!
