Not going to enter the brake debate but the one I fly ise set up with just a little brake right at the extremes of rudder travel. This isnt right and on some cross wind take offs having brake applied when you least want it isnt good.
I'm not going into this one again, either, having had a
vigorous debate with SSD in another place!
However, I'd be very concerned with your Chipmunk to ensure that FULL rudder travel is available, despite the brakes being misadjusted. Attempting to recover from a spin is not the time to find out you haven't!.
