Increasing torque in tail draggers?

Lately I have been spending most of my FS time flying "war birds." I wonder if there is a way to tweak the torque so there is significant yaw when opening up the throttle and also when raising the tail on take off? The best example I have is the RAS Spitfire, which models this superbly. (And just about everything else!)... Other than adjusting the aircraft.cfg file, the only other tool I have is AirEd so maybe what I want to do isn't really possible with such limited tools (and skills) but no harm in asking.

ps. If the new Flight1 Air Wrench tool can help me do this, that would make it worth buying for me...

Any assistance would be greatly appreciated
