You could use one of these http://www3.towerhobbies.com/cgi-bin...&I=LXAFN1&P=ML and just connect the reversing leg of the Y. A JR version is also available.

Just reverse the channel that the servo is pluged into. (at the radio)

but Mr G is right about reversing at the TX if that will do the trick for you. What radio TX do you have?

both servos go into same slot on the reciver, theres a Y connector.

Refer to page 20 of your JR XR2i Manual which advises "The Servo Reversing feature of the XR2i is a very convenient feature when setting up a new model. The purpose of the servo reversing function is to change the direction of the servo rotation in relation to the wheel/trigger movement. The Servo Reversing function is available for the steering and throttle of the XR2i." and gives pictorial instructions on how to reverse each servo's direction of travel.
Instructions for DIY servo reversal, for those who can not use a TX function, are under "Servo - alterations, calculators, databases, repairs, convert to an ESC or winch & FAQ" on my web page.

Let's not get him digging around inside servos. Not unless he is GREAT at soldering. Real good way to screw up a servo. [:@]

i found in one of your links that futaba and hitech servo's move in opposite directions, i might just buy a futaba servo but if my lhs has one of those reverse y connectors bruce links i may get that being cheaper and all.

IT'S CHEAPER TO FLIP THE REVERSING CONTROL IN THE TRANSMITTER-------LIKE FREE AND INSTANT. AT LEAST TRY IT BEFORE SPENDING MONEY-SHEESH!!

Since you are on a non reversing Y, it won't do any good to use the reversing switch on the transmitter as both servos will reverse. You have three choices, buy a different brand servo (yes, Hitec and Futaba rotate in the opposite directions with the same signal), buy a Y with a servo reverser on one branch or, modify the servo internally by reversing the motor leads and the two outer leads on the potentiometer (not an easy job on some servos).

OK, my mistake, I didn't see "both servos go into same slot on the reciver, theres a Y connector" is your earlier post. Get the reversing Y I recommended earlier. Safest bet/cheapest.
