some times the controller is say on 27 meg and the reciever is say a 29 meg ,if its not that the crystals may be in the wrong item ,check the crystals they have tx and whatever freq and the reciever has rx whatever freq,and if its not that it could a dud cystal or reciever or transmitter or even the power supply in either item isn't the correct voltage.


just a few things to check. hope it helps.

Make sure that the crystals are the same frequency,also make sure that the batteries are fully charged...

didn't say different crystals i said they have transmit and recieve crystals having a for eg. RX 27 .695 in thetransmitter will not work and aTX 27.695 in thereciever will not work it all needs to be swapped .


tx 27.695 in the transmitter and rx 27.695 in the reciever.
