Last night I soldered on a new antenna, to help with the range
on my new supra. After I was finished there was no noticable difference. So I opened up the controller and noticed it's a rev. 5 board and a new cripple capacitor. You have to take off the 2 screws that hold the board to the front of the controller, it's on the opposite side of the previous cripple cap., it'll be the only one there with a number 8 on it. Hope this helps.
