Piccadilly Lily is an excellent addition to the FS-Cast B-17's texture list but adding it and then going for a hop with the new bird brought back an old problem I'd forgotten about, which is the aircraft's ability to be turned while taxiing. There are a number of other B-17s in FSX that taxi very nicely indeed using differential braking as applied by the flight model along w/rudder application. I can go through all the flight models to find the correct one, but before I depart on that safari, I'd like to know - is there a setting in the differential brake section of the aircraft cfg that can be altered slightly to give the engines/brakes that will be applied for a given turn a little more authority?

I do not have a joystick w/four individual throttles and two separate brake pedals. Trying to compensate.
