I just bought the HiTec 645MG servo to replace my stock throttle servo in my XT, however it seems that it is geared different then the stock servo meaning using the brake on the radio applies throttle with the HiTec servo.. Is there a guide as to how to properly install the servo or could anyone please help with there person suggestions to fix this issue.. Im sorry if this seems like a dumb issue but I'm new to the 5th scale world and I'm completely upgrading this XT to familiarize myself with the bigger scale RCs...

Hope someone can help!!
