Add an elevator setting to the <cruise> element; otherwise, neutral

Browse source 
elevator and trim give ridiculously high airspeeds.

Increase the elevator effectiveness slightly.

Increase the vertical stabilizer effectiveness, and give it a 1.5
degree incidence angle, to compensate for asymmetric propeller
effects.

Increase the rudder effectiveness to help with cross-wind takeoffs and
landings.
