Reverse / brake issues with ttx300

[MrBlank]

I picked up a ttx300 radio a while back, but never got around to hooking it up until recently (just bought a 3racing winch) and was using a 2 channel Traxxas 2.4 for my sawback.

I have a wp1060 ESC, and I understand that in forward/brake/reverse mode you only have 50% reverse (I did with the traxxas radio), but appeared to have strong braking and 100% reverse in forward/reverse (dragbrake) mode when using the traxxas radio.

Since hooking up the ttx300 about a month ago I have had very slow response / weak braking and about 10% torque/speed in reverse in f/b/r mode. In f/r mode I have excellent forward and brake, but reverse is still less than 100%.

I have made countless attempts to reprogram it without any luck, and the manual is little help.

I took it back to the store where I bought it yesterday, and the store owner (who is heavily involved in on road electric racing) said it could not be "fixed" made 2 claims:

1 - the esc is at fault (we hooked up another radio and proved that to be incorrect)

2 - the radio's reciever is too weak, and tactic (or another compatible company) does not make a more powerful reciever. He suggested I solder a capacitor between one of the servo wires and tried to sell me one for $20 which I refused. He claimed the servo is stealing all of the power from the reciever. I suggested that I use a bec to power the servo (have one yet to be installed) and he said that would help, but either capacitor or bec - my reverse / braking gains would be almost unnoticable.

Does any of his explanation have merit? I feel as though brake and reverse should be adjustable, but he claims those adjustments are esc only and my "cheap" esc is at fault - he kept jumping back and fourth.

Any idea what I can do?

Methinks you need to calibrate your Tx and esc.
I ran that on a couple of rigs and had zero issues.

I do not know of any way to calibrate the wp1060 ESC as it uses a jumper system, although you can correct me if I am wrong.

I just took it in to my usual hobby shop a couple of hours ago and he spent 15-20 minutes wIthaca me trying to follow the programming directions in the radio's manual - in the end he said that an ESC with more programing parameters was the answer. It even appears as though the throw on the trigger in reverse is less than half that of the forward throw.

Calibrate the throttle range:
Turn on the ESC switch, set the throttle
stick on your TX to the neutral point and then wait 3 seconds for the completion of
throttle range self-calibration; Beep sound emits if the self-calibration is
sucessfully passed, then the ESC is ready to run

there is no additional step to calibrate the esc throttle, as long as the throttle trim is set properly on the TX the esc automatically calibrates every time it is turned on. That being said, when its seems to be less than full reverse is the LED blinking while in reverse?


• When the throttle stick is in neutral range,
red LED is off
• Partial throttle forward, partial brake or
partial reverse, red LED blinks
• Full throttle forward, maximum brake or
full throttle reverse,red LED is solid on

Clear the ttx300

Several of the TTX300 features are adjusted electronically by entering the
programming mode. To enter the programming mode, follow these steps:
1. With the transmitter turned off, turn steering wheel full right, pull the trigger
to the full throttle position and turn the transmitter’s power switch to ON. The
LED will fl ash to confi rm when performed correctly.
2. Release the wheel and trigger at this time.
End Point Adjustments
Steering:
1. Enter programming mode.
2. LEFT EPA: Turn wheel FULL
COUNTERCLOCKWISE, use 3rd
channel push buttons to adjust.
3. RIGHT EPA: Turn wheel FULL
CLOCKWISE, use 3rd channel
push buttons to adjust.
Throttle:
1. Enter programming mode.
2. THROTTLE EPA: Pull trigger to the
FULL THROTTLE position, use 3rd
channel push buttons to adjust.
3. BRAKE EPA: Push trigger to the
FULL BRAKE position, use 3rd
channel push buttons to adjust.
