Well first thing Sonic, welcome to the Zone!

You have 2 problems, 1 is the reversing, the 2nd is your radio legal?

If the radio was made before 1991 and has not been "Gold Labled" as narrow band FCC compliant, it is illegal to use. It may cause interference to other pilots who are next to your frequency.

To reverse the throw of the servo, you must reverse the throw of the stick internal. Since you don't have that, see problem #1.

You may get an answer in the Science section, but I still refer you to problem #1.

In all honesty, your best fix "MAY" be a new radio!

STOP Don't do that you will let the smoke out. By changing polarity you are not just changing the polarity of the motor but also the electronics in the servo. You <font color=red>WILL</font color> ruin the servo!
If nothing else see if you can rearrange the position of your servo, arm or pushrod to work with your setup.

Hi:
If you are handy with a soldering iron, just reverse the two outside leads on the pot which your stick drives. This will reverse the direction of the servo.
As above, DO NOT change the leads going to the servo. You can buy an inline servo reverser which I suppose would also work with the ESC. By that time, you would be better off getting a new transmitter, which will make all this easy.
Regards,
Bob Stewart

Or you can switch the leads to the motor in the servo, and reverse the two end leads on the pot (use thin wire to do this). Not really recommended but will work in a pinch.
