Model # was on the box for mine. From what I've read so far, if it was originally meant for a summit, it's the wrong one. Receiver should only be a 4 channel, with two channel 1 slots (dual steering servo hookup). The summit receivers, I'm told, have 5 channel slots, also with two channel 1's. Not much help, but best I can tell ya. Good luck! "thumbsup"
