RE: Servo Reversing
One other solution, different brands of servos turn in opposite directions with the same command input; i.e. Hitec and Futaba will turn in opposite directions. Now, the hard part, getting two different brands of servos that match in speed, travel distance and power. Another solution, if your transmitter supports mixing, it may be possible to put the two servos on different channels of the receiver and use a mix to operate them.
