How slow is slow?

What is the throw in degrees?

Gap sealing will generally increase the aileron effectiveness about 15 to 20%.

I have found that the roll rate will increase as the CG inches towards the rear. The speed will also go up considerably as the CG becomes correct. However stall becomes more pronounced.

If the ailerons are reflexed the roll rate and speed will be slower.

Passive boast tabs will sometimes assist in speeding up the roll rate but is a more complicated subject.
