Single servo on a Hawk is not acceptable and, if I may say so, told you guys so on the Hawk thread some weeks ago. That loss was totally avoidable. My Hawk has twin 8511s, and has beautiful, solid, pitch response, and that is recommended now on Skymaster's website. I also recommend mass balancing the stab. With this set up my volt logger records minimal voltage drop on the Rx bus during a flight, an indication that the servos are not being hammered.

And sorry, Tom, BV is wrong, in my opinion, to actively discourage, without qualification, Matchboxes, they are great devices, its the way that they are used which needs clarification. In the Bobcat application if using a matchbox, it would be best to route ONE elevator servo via the matchbox and the other direct from the Rx so that if a Matchbox fails, and none of my 15 have, then the directly powered and signalled servo remains active, and if pitch response is diminished as result of a matchbox or the other servo should fail, you still have pitch control remaining, particularly if you have a higher rate available by selecting another flight mode. This is the way I have set up my FC Mig 29 with two ganged servos on each stab. Same for ailerons. But , sure, if you dont NEED to use a Matchbox leave it out, match servos via the tx software and totally remove the chances and consequence of failure.

We have the hardware and software available to make our jets safer and less vulnerable if we choose to find out how to use our radios to their full power.
