Hi there WoodiE and thank you for the welcome.
I only found this forum when looking for "How to Info" on the Dumbo X6 radio setup.
I live on the Gold Coast, Queensland, Australia and have been involved in RC, planes, hellis and quadcopters for the past 45 years.
I bought my first RC car about 2 years ago and pulled the trigger on an Arrma Senton 3s BLX in April, not into anything daring as yet and have only run it on grass.
I guess I have a lot to learn, so will keep in touch via the forum.
Have a great day.
Tanks again WoodiE, Without those detailed Dumbo instructions I would have been up the creek without a paddle.Welcome! I spent 6 months in Cairns and worked my way down the Gold Coast some 20 years ago. Ok... 25. I'm in Ottawa, Canada.
I have a Notorious as my first Arrma and a DumboRC X6A and an X6 with a handful of receivers. If you have any questions I'll be happy to help if I can.
It doesn't have separate end point adjustments, just dual rate. What you do is set everything to max D/R and trim to the center. Then run through the procedure to calibrate the DumboRC controller. When that is done, do the throttle end point setup on your ESC. Finally, set your steering dual rate down to say 50% and then slowly turn it up, observing when the steering hits the end point on either side. You want the steering dual rate set to something just a bit lower than the maximum steering travel on whatever side it binds on first. Ensure that when you hold the servo full left or full right it is not making noise or flexing something trying to push the steering past it's maximum.Is it possible to set EPA with DumboRC?
Yep, on the Dumbo you can turn channel 6 anywhere between 0% (counter clockwise) and 100% (clockwise).Great thread with great information. Now can anyone tell me if it's possible to turn off the ABS feature on the receiver? I wish I could disable it, but cannot get even a clue on how to do it.

Do you mean turn off the gyro function? ABS usually refers to anti-lock braking, and that is not a feature of this radio system.
The gyro function can be adjusted as above, or disabled by pressing the button inside the end of the receiver.
If you do mean braking force, that is an ESC setting and it is configurable in your ESC’s setting menu. Max braking force can normally be adjusted to 25%, 50%, 75%, or 100%. You usually want between 50% and 75%. If your rig is not stopping quickly enough you may need to increase Max brake force.
Are you running 100% dual rate on your throttle? Something tells me you are not....
I think I understand....I'm Slow.
I've watched the video 3 times. I'm seeing no change in behavior with the Gyro off and when it is on. What are you trying to illustrate?
Seems like an appropriate time to link this video:
I think I understand....
If there was ABS, the car would have proceeded to turn left during full brake regardless of Gyro on or off?
I picked one up but it won’t bind at all. I have 2 receivers and the transmitter won’t bind to either. I’ll stick to my futabaFor those who pick up this rx/tx combo I found the below info extremely useful when I purchased. These words are not mine FYI but I did pull from an amazon reviewer. Thought I would share for those looking for info. This relates to the dumbo x6 with gyro.
How to bind the DumboRC transmitter to the Receiver:
1: connect the receiver to power:
1a: +5 volts (red wire) goes to any middle pin
1b: -5volts (black wire) to any pin close to the receiver's edge (farthest from the antenna)
2: Turn on the transmitter.
3: To bind the receiver, find the tiny black button in the hole next to the antenna. Use a paperclip to hold the button down for 1 or 2 seconds. 3a: The green LED should blink for a few seconds while it binds to the transmitter. Then the LED should be steady.
How to turn on and off the DumboRC receiver gyro:
1) connect the receiver to power. The green LED should be lit.
2) with a paperclip, push the little button next to the antenna three times in quick succession.
3) The red LED should blink and then remain on -- meaning that the gyro is activated (both red and green LEDs will be lit)
4) Again, push the button three times, and the red LED will turn off - disabling the gyro.
5) It's important that the receiver be mounted horizontally on your car -- I had mounted the receiver vertically, and did not detect any gyro action when steering.
Here's how to get into settings mode (for the "upgraded" version):
1: turn off the transmitter.
2: pull the throttle/trigger all the way backwards (against the handle-stop).
3: twist the steering wheel full counterclockwise.
4: with the trigger backwards and steering ccw, turn on the power.
5: let go of the steering wheel and throttle/trigger.
6: push the Channel 3 button (below the trigger)
7: the top light should start blinking.
8: now, with the light blinking, reset the neutral position of trigger and steering:
8a: twist the steering full cw, then full ccw, then let go
8b: pull the trigger full backwards, full forwards, then let go.
8c: turn off the power switch.
You must do steps 8a, 8b, and 8c, or else your RC model may not drive backwards, or may not go forwards!
How to set the direction, zero point, and sensitivity for the throttle and the steering:
Open the top cover to find two slide switches, and four knobs. The left switch and 2 left knobs are for steering. The right hand switch and 2 right knobs are for throttle.
Set the top left switch for either normal or reverse steering. (really, changes the direction of the steering wheel). Set the middle-left knob for the zero-point of steering (just point its arrow straight up at first). Set the lower-left knob for the steering limits (start with it pointing straight up, adjust as you please)
Set the top right switch for either normal or reverse throttle (just changes what happens when you push or pull the finger-trigger). Set the middle-right knob so that your model does not move when the trigger is in the neutral position. Set the bottom-right knob to control the speed limit of the trigger.
You can change between ordinary throttle-steering to mixed steering-throttle ("dual-motors" or "tank" or "v-tail").
Normal steering mode means the finger-trigger will control one servo for the speed. The steering wheel will control a second servo which turns the steering mechanism.
Mixed steering mode is for a model with two motors - a one motor driving the left side of the model and motor on the right side (think of a military tank). With mixed mode, the finger-trigger controls the speed of the model, and the steering wheel controls the speed difference between the left and right motors.
To change from normal to mixed steering mode, do this:
1: turn off the transmitter.
2: pull the throttle/trigger all the way forward (towards the front of the transmitter).
3: twist the steering wheel full clockwise.
4: with the trigger frontwards and steering CW, turn on the power.
4a: the LED on top should blink red-blue.
5: let go of the steering wheel and throttle/trigger.
6: pull the trigger all the way backwards (against the handle-stop)
6a: the top LED should change to solid color:
6b: if the LED is blue, then you have normal steering
6c: if the LED is red, then you have mix steering ("tank" or "v-tail")
7: set the top switches:
top left switch is steering normal/reverse
top right switch is throttle/trigger normal/reverse
8: set the steering & throttle
