Help???

I was helping a friend out with his Aerobird extreme and he crashed it while on his own, which resulted in replacement of the V-tail.

My question is why is the direction of control surface travel opposite to that of the ailerions.

ie to turn right the Left surface comes UP and the Right surface moves DOWN

this was checked as per the instructions that come with it.


Thanks in advance

I will leave a detailed explanation to the aerodynamics experts but, the simple explanation is that ..........

If you rotate each v-tail side to vertical (one at a time) so that it is in the position of the fin / rudder , you will see that each works like a rudder turning the aircraft. Aileron causes the aircraft to roll toward the side you lift - rudder tends to point the aircraft and with the design of your wing, it will end up rolling in that direction.

Yep, just think of it as a rudder.
I once had a V-tailed powered glider (called the Electra-Lite) that seemed to turn a little "flatter" than other gliders, maybe because the v-tail tended to roll in in a direction opposite the turn.
