Yes, I hear the clunk sound but the trailer does not lock on to the tractor. I am not sure if I have engaged the servo from the radio, I have a four channel Acoms, how should I have done this? Many thanks for your help

I have built Reefer Trailer with morotized support legs, I can get the legs to work manually but cannot get them to work with the multifunction unit on my Knight Hauler. I have fitted third servo for the legs but cannot get servo to work nor can I get the trailer to hitch up to tractor unit, either manually or with the multifunction unit. What am I doing wrong, please can you help?
