okay, so i plan on racing electric 12th scales by the summer, at earliest, and have a question. since i have the futaba 2PL, (dont hate, i love simplicity, lol) which im pretty sure is the AM, how will i use the transponder? im not sure if the battery slot is filled, or if its empty, because cant the reciever get power through the esc, which goes into one of the servo spots? or is there any 3 channel AM recievers, or any FM recievers that work with the 2PL?
