I have an Axial rock crawler that came with a Spektrum DX3.0 which according to the manual can store 4 models, I assume this means 4 different cars. I am working on an old goldpan and figured I would just get another Rx and use the DX3 for that as well. I bought an OrangeRx GR300 which is supposed to be just like the Spektrum SR300. I followed the binding instructions in the Spektrum manual and this is what happens. I attach ESC, motor and battery to the Rx, I install the bind plug and turn the ESC on and a rapid blinking light appears on the Rx, I then hold the bind button on the Tx and turn the power on, as soon as the green light starts to blink I let go of the bind button and the light turns to a solid green in a matter of seconds, while this is happening the light will on the Rx will either go out or turn solid for a fraction of a second and then begin the rapid blinking again. I remove the bind plug and try to throttle the motor and nothing happens. I am sure the ESC and motor work because after a few tries I took the SR300 out of the Axial and hooked it up and everything worked fine. I have tried holding the bind button longer, pulling the bind plug out as soon as the light stops blinking but it still returns to the rapid blinking and no function. Sorry this is a bit long winded but I hope some one can shed some light on the issue. Thanks.
