Also, PM me on how much you can get me a Futaba 4PKS-R for.

Thanks,

7.5 is too much of a difference, gotta say no on that one, I'll pm the price on the radio tomorrow.

Spektrum DX3 Radio
Spektrum 300 Receiver
Spektrum 3100 Receiver
Orion 3800 Pack
LRP Sphere Comp
Novak Ballistic 17.5

I plugged everything in, bound the receiver to the radio, I synch. the ESC to the radio, when I turn it on, the motor won't turn and the servo only turns one way. I checked both receivers, bound them correctly, per manual, and still nothing...It's like the signal is not getting to the Speed Controller....Any suggestions??

Once again, these are loaner electronics, and I don't want to mess too much with them....

Thanks in advance...

The servo only goes one direction, with both receivers doing the same thing? (that tells me a bad servo or radio, possibly a bad receiver but that normally goes bad both directions), The receiver binds correctly?

Unplug the servo (take it out of the equation). Try the speed control by itself. If the speedo works in the throttle socket (2 or T), then try it in the servo socket (1 or S), it should work using the wheel on the radio. If it works in both slots fine - bad servo.

If there is still a problem...use one of those 4 cell (AA) battery holders to power the receiver and servo. Test the servo in both steering and throttle slots. If the servo works fine in both, bad speed control.

The third test requires a second, known working Spektrum radio to test both receivers. If a second radio works fine with the receivers, servo, and speedo, then the radio is bad.
