No, you shouldn't use the 'Set' functions while your simulation is running unless you're resetting an object. If you want to move an object in ODE you should apply Force and Torque only, either to a body directly or via joints ;)
The best way to turn a flying vehicle would probably be adding relative force...
The following will rotate to the left (left wing down):
dBodyAddRelForce(ode\body,-40,0,0)
The following will rotate to the right (right wing down):
dBodyAddRelForce(ode\body,40,0,0)
