I've lost reverse Dx4c

[PCK_4xCustoms]

Got a fleabay TH listed as having a blown up transmission for a song.

After a bit of investigation, all looks well just a shift servo stuck in neutral and no programing in the Tx.

Transmitter: Dx4c
Receiver: SR310
Motor: stock dynomite
Battery: stock 2s lipo

Reset the Tx, set button E to Aux1 2p.

Lost reverse.
Still have forward, but zero reverse. ESC shows red light when attempting reverse.

Any suggestions? I've run through the settings a number of times and havent found a setting that removers the brake/reverse setting for the trigger.

If your ESC is flashing red when hitting reverse, Its not the Tx..

It would have to be an ESC setting..

That or a mechanical issue ( stuck brush or faulty brush perhaps)

The ESC flashing red shows that its getting a signal from the Rx to go backwards.. Why its not would again, have to be a setting, or failure.

My next check would be switching the motor wires to force it to spin the other way, To confirm its not mechanical. Then I would start messing with ESC settings..

Good luck

Sounds like your ESC has changed 'modes' on you. Happened to me recently too.

From the "Tazer 12T" ESC's manual:
=================
Transmitter Controlled Programming
1. Power on the transmitter and set the transmitter’s throttle endpoint travel to maximum and the throttle trim to the center position.
2. Hold the throttle trigger at the maximum forward position, then power on the ESC.
3. Continue holding the throttle trigger at the maximum forward position until a beep sounds and both red and green LEDs flash, then release the throttle to neutral/stop position.
4. The ESC is now in programming mode. The ESC will cycle through its programmable features in this order:
A. Green LED only: Change Battery Chemistry Type: Ni-MH or Li-Po
B. Red LED only: Transmitter/ESC Endpoint Calibration
C. Red + Green LED: Change ESC Running Mode: Forward/Reverse with Smart Brake, Forward Only with Brake or Crawler Mode
5. Move the throttle trigger to maximum forward position and back to neutral/stop position at A, B or C in order to execute the setting task:


C. Change ESC Running Mode: Forward/Reverse with Smart Brake, Forward Only with Brake or Crawler Mode
• The respective LEDs will indicate the currently selected ESC running mode for 4 seconds:
Green LED Solid: Forward/Reverse with Smart Brake
Green LED Flashing: Forward Only with Brake
Red and Green LED Solid: Crawler Mode

• Move the throttle trigger to maximum forward position within the 4 seconds to select the next ESC mode. A beep will sound and the respective LED will indicate the new ESC running mode
• To select the next mode, repeat the step above within 4 seconds of the beep
• Both red and green LEDs will flash 3 times with 3 beeps
• Power off the ESC and then power on the ESC to return to normal operation

At any time that the ESC is powered and the transmitter is at the neutral/stop position, the respective LEDs will indicate the current ESC running mode:
Green LED Solid: Forward/Reverse with Smart Brake
Green LED Flashing: Forward Only with Brake
Red and Green LED Solid: Crawler Mode
=================

Hope this helps you out of your jam.
