Sopwith Camel flight model update including trim 1

I've had a few requests for turning on the trim tabs on the camel to make it more controllable, and here it is.

I've adjusted the trim setting to provide for a smooth and even adjustment, but I've been using a joystick axis to set my trim and can only hope its acceptable to people who use button based trim.. I hope you enjoy.
