I am putting a new Kyosho ducted fan together and am having trouble with the electronics. I purchased one of the small 4 chanel recievers, mini servo's and battery. The trouble is, when I plug in the battery to the reciever the servo's move slightly, just for a split second but the servo's do not mover via the transmitter. The transmitter is from my PICO ECO helicopter and works fine on it. I removed the crystal from the HELI and used it in the plane. The reciever is for 72MHZ and thats what the crystals are. Any recomendations?
