I want the 2 elevator servos on my model to operate in opposite directions
using a Y lead.

Is it just a matter of reversing the + and - wires on one side of the Y
lead, or is it more than that?

I know I can use ailevator setting on my TX, but it's only a 7 channel RX

Thanks in advance

It is a lot more than reversing the wires on the Y-lead. All that would do
is burn up the servo's amplifier chip.

You have to reverse one of your servos, meaning that you have to disassemble
it, reverse the wiring of the motor and then reverse the outside wires of
the feedback potentiometer. This used to be simple to do when servos were
"wired", but most of today's servos are mounted to a PC board, making this
difficult to impossible to accomplish. Your best bet would be to contact the
distributor of the brand of servos you have and see if they offer a servo
reversed from their stock.

Good luck.

HS-55 servos are done the 'old' way. It's a pain to see anything with the
wires so small, but I've successfully reversed two of them.
