As Larry wrote, there is fairly detailed instructions in SECTION 5
on how to evaluate the shape of control surfaces with bent (vs riveted) trailing edges, and how to adjust them if the shape is not correct.
The shape / profile is far more important than the actual bend radius of the trailing edge.
This is equally important for the ailerons, elevators, and rudder.
Next on the list of things that can make an RV fly bad is control system friction. This is particularly bad in the pitch circuit.
For the best flight qualities (and static and dynamic stability), the control system should be very
low in friction.
I.E., if you flick a control surface, it should move and bounce around without quickly stopping.
Sometimes solving this just requires doing some good lubricating but it is usually caused by excess friction being induced by improper assembly.
