Just a side note, the calcs I did on the original Isobar at 200 MPH and full deflection of the elevators, the force was 220 OZ. At the time, the only servo available was 8411 at 155 oz. By the way, testing of the servo showed 1.5 on the servo at 155 oz torque.

Even if you doubled the size of the control surface (which the hawk certainly is at least double), you are more than double the torque with the 8711, and the odds full deflection at 200 mph??

With these higher end digital servos, none of us are flying them to their "limits", in fact even the most abrasive maneuvers are not likely to push these servos enough to even make them warm.
