Uncontrollable B4.1
1 Week ago I upgraded both of my cars (TC4 and B4.1) to 2.4ghz. Since then I haven't been able to drive it because it goes backwards when I try to go forwards, vice versa, and it goes faster backwards than forwards. However I didn't have any trouble with my TC4.
Electronics
XP Digital SC450-BL ESC
Reedy 3300kV Brushless Motor
Futaba 4PL Transmitter
Futaba R2104GF Receiver
Possible Problems
I had to unplug the motor wires to clean the car.
The receiver/transmitter has to be setup.

Ok...You were right...but it still goes faster backwards than forwards.

then...
change the reversing switch on the radio(the throttle channel) then recalibrate the ESC to the radio.

RE: Uncontrollable B4.1
some ESC's only like the transmitter in norm or revs. sounds like yours likes normal.
so, i take it if you put the tx in norm, and program the ESC thats when you get the truck going backwards instead of forwards?
typically when you have an issue like yours its solved either by programing the ESC with the Tx in the opposite setting from what it was in...or just swapping 2 of the motor wires.
some ESC's have a "motor direction" setting. maybe yours does and it needs to be changed?

RE: Uncontrollable B4.1
I fixed it. First I reversed the throttle, then I reversed the steering, and last but not least I had to re-calibrate the throttle settings.
