- This is how you calibrate a DumboRC transmitter.
On a side note, I keep calling it a receiver... It's a transmitter.
1. Turn off transmitter and ESC.
2. Hold full left and full throttle.
3. While still holding, turn on the transmitter.
4. Release steering and throttle.
5. Press the channel 3 button(The light starts flashing).
6. Move the steering and throttle to all there endpoints(Full left/right/throttle/brake).
7. Press the channel 3 button(The light stops flashing).
You can download the manual from here: www.dumborc.com...
Or just look at the image I've uploaded here: imgur.com/sR5Pni9
If you light is red, then you're in mixed mode, and should probably look here: th-cam.com/video/QSuJE7gcdDA/w-d-xo.html
Many thanks this happened to me today LOL, I had to come back to this video which is very good !
You my friend has just saved my 2 week nightmare. Thank you so much. I have subscribed for that and will watch future videos uploads.
Good Video keep going.Helped me a lot cause whenever i tried to revers my crawler it shot off full speed,altough i only gave like 1% throttle.Luckily it works now.Thank U
Thank you so much I just got this and I was installing it and messing around with it and I thought I broke it you have relieved me lol thxxx
finally i can manage it, very helpful tips thankyou.
Nice. Thanks bro. I will try it on my RGT. Having problem since the Receiver got wet. It will still run but suddenly it will stop. Sometimes if you pull the run trigger the Steering will also turn to right or left.
Hi! Did you get a solution? When I push buttons on channel 4 the engine start a little...
Thanks man will save this for if it ever happens to me
I hope this finally kills my steering from freezing. From time to time i have this issue.
Did it work? I have the same issue
@@duncanaronstein7462 nope. I bought another one and made a cross check. It is the problem of the transmitter not the receiver. I think mine is damaged. The second one I bought is working fine.
Thank you, i get the same Transmitter
Awesome video
Sir there is no need for trim nob calibration & other channel
I have noticed that with this transmitter the steering has to be switched to reverse but the trimming is in opposite direction??? Does anyone have same issues?
I do
@@rcadventuresoffical And, what is the solution??
There's no solution, this is just how it works.
The only thing you can do, is to remember it yourself, that or just write down.
My remote throttle controls the steering on the car and the steering on the remote controls the speed on the car. How do I fix that
You have swapped the servo and ESC connectors on the receiver.
Servo goes in number 1, and ESC in number 2.
I tried what u said yet red light on top is still on... when I pull trigger it goes forward and wheels turn left. Turning right makes it brake and turn
You got it set to mixed mode, and need to revert to normal mode then calibrate again.
Red light is mixed mode and blue is normal.
Here's a new video showing how: th-cam.com/video/QSuJE7gcdDA/w-d-xo.html
@@RandomloserDK o that makes since thx....how do u change modes. i lost manual.
@@williamcoolidge6284 Look at the video above.
Thank you sir
Cheers mate
@BJ's Random RC's What happens if you have calibrated your tx and rx, but your esc keeps beeping, this happened when I used a esc programming card, I have also have reset it, but the beeping is constant, basically its not arming.
My best guess would be, the steering trim isn't centered.
@@bjsrandomrcs1352 Same shit, I will wait 2 weeks it will reset like it did before, I think time for a new proper esc.
My issue is that instead of centering it turns the opposite direction meaning I'm turning right and lot go and it decides center is hard left and then If turn right nothing but if turn left again it's already left.... and let go it centers and vice versa is this some type of setting.... interestingly it only does it in a certain vehicle
It sounds like you didn't have the servo centered, befor you connected the servo arm.
@@RandomloserDK it was working fine I just lost the radio so I got a dumbo x6 it works in other vehicles just not the the tekno sct I didn't touch the servo... could it be bad... the servo thx for your help
@@shenanigan3083 Did you have a shared transmitter in the tekno or did it have it's own?
@@RandomloserDK it hade its own.. lost it.. and car sat for 4yrs.. I pulled links off servo left horn on and it seemed to be fine but again I didn't change anything and it was fine the last time I ran it
So I really need some help so I have This for my Arrma TLR and basically my main problem with the controller is that forward on the controller is not actually full power but reverse there’s allot of power and when I check my setting on my esc my reverse is at 25% and my speed is at 4, so I don’t know why it’s doing that it feels that reverse is faster then forward
So when you reverse and switch to forward, does it brake or does it go forward immediately?
@@bjsrandomrcs1352the whole problem is that Reverse has more power then forward, when I throttle it forward it feel like the car is only pushing out 30% power even though my punch level is at 4 and my throttle trim is maxxx
It’s basically like it’s reversed the forward motion is slow while the reverse is tons of power
I asked about braking, is because it sounds like you have to reverse the throttle and maybe also the motor.
There's a number of combination at play.
By identifying which throttle position activates the brakes, you narrow down the possibilities.
For example, when you try to accelerate the ESC might receive a reverse/brake signal, but if your motor is also wired in reverse, the car still goes forward, but at reversing speed.
@@bjsrandomrcs1352 okay I will try that out today and see what happens and get back to you thank you for helping me out man!!!
I did this and my rc still doesn’t go to the left side it also has reverse issues
Lmk what it can be
Did you center the steering trim first?
@@RandomloserDK Im not sure what you mean with that but I think we found the problem is that servo, transmitter, and the receiver they should be here soon so hoping it’s an easy fix
I need help. My RC car accelerates when I push my throttle back, and my RC car breaks when I push my throttle normally...
There's a switch on the transmitter, that changes throttle direction.
I don't remember what it's called, but look for something like "Th dir" (Throttle direction).
@@RandomloserDK yeah i saw that but its not safe since it goes instantly from acceleration to brake. And its also slower
It goes quick backwards and slow frontwards
There's two things that switches direction on the motor.
1. The transmitter switch.
2. The motor wiring.
If it's the wiring, then swap two pairs.
@@RandomloserDK how do I know which wires to connect? They are all black - one colored
I did calibrate many times, but when i press the throttle, car goes backward..
How to solve?
There are two ways to fix it depending on your circumstances.
1. The transmitter have a switch for throttle Normal/Reverse.
2. If your motor is brushed or sensor less, you can swap two of it's wires. (If it sensored do not try this).
@@bjsrandomrcs1352 i tried those two solutions..but:
1. I switch to rev..and car goes forward..but the break lamp turns on.
2. I swap its wire to ESC...but no respond .. no power..
So..im stuck lol
I hope you only swapped the motor wires between the motor and ESC.
And NOT the ESC to battery wires.
What kind of motor do you have(Brushed / brushless sensor less / brushless sensored)?
@@bjsrandomrcs1352 yes i swapped the motor wires..
Mine is brushed motor..
I hv no idea what's wrong and getting a bit frustated.
Thank you for replying my comments..i really do appreciate it
Okay, as I see it, your transmitter throttle needs to be set to normal(In your case).
So it's a matter of swapping the motor wires.
Check and ensure they have a good connection.
Try turning the car off and on again.
Hi
I have the JLB Cheetah 120 amp RC car. The problem that I'm having right now is when
ever I want to go faster there's... on my Dumbo RC remote.
Whenever I turn the top throttle button to 3 it moves backwards on its own.
The top is 0-3 left and right.
As for the bottom throttle button for speed. 0-100.
Whenever I turn the bottom button...to 75% of 100, the car moves forward by itself.
Can you help me fix this problem?
The top dial is for centering the forward and backwards movement, in most cases you leave it at 0 or use it to find the ESC's zero position (Where the car doesn't move by itself).
The bottom dial is for limiting the top speed, and should be left at 100 unless you want to go slower.
It sounds like you need to adjust the top dial around 0.
Depending on the ESC you use, you might also need to calibrate the ESC to transmitters endpoint's.
ESC's from companies like hobby wing has this feature, but many cheaper ESC's don't.
@@bjsrandomrcs1352
Okay I tried to put to at 0, but it reverse moving by itself.
As for the speed, I have to have it between 75 and 50% for it to stay steady without any movement.
So I never really hit the maximum speed.
For example if I set my throttle speed button to 100% while it's off. When I turn on my remote control then car, what's going to happen is my wheels are going to be spending real real fast until I turn it down to like 50% and is going to stop.
I was thinking that I need to recalibrate it. Could you tell me how to recalibrate it back to the factory settings.
If you calibrated the transmitter, you might have touched the throttle trigger while setting the neutral position.
That would cause the neutral, to be the same as the amount of forward movement, that you are getting.
If that's the case, recalibrate the transmitter like in the video.
@@bjsrandomrcs1352
ok
@@bjsrandomrcs1352
Hi,
Ok when I re-calibrate my remote... do I put it to maximum speed at 100% or do I put it to 0%
I forgot to mention to you that my brakes are too strong with a sudden stop. It just won't stop easy. What percentage do I put my brakes on. This is the best way I can explain it.
I did everything you did & my transmitter made all of the same color lights but then at the end when you pressed the ch.3 button & the light went solid mine just keeps flashing, please help cause I'm about to smash this transmitter with a hammer 🔨
Try to record the process and upload it to TH-cam.
It's hard to know what's going on, without seeing it.
What if after all this youre speed is reversed like reverse is forward speed and forward is reverse speed
Then you flip the TH switch(Normal/Reverse) under the top cover.
@@bjsrandomrcs1352 i did still was the same just reversed ended up being the motor wired even though it was supposedly wired correctly owell works great now!
If your ESC can be programmed, there's often a reverse motor setting.
If not, then you need to swap two motor wires.
Any two wires is fine(Works on brushless and brushed motors, but Not on Sensored brushless motors).
And possibly also reflip the TH switch.
@@bjsrandomrcs1352brother i used this dumbo rc approx 1.5 years without any problem.but today i faced a problem . Not everytime , sometimes when i used steering wheel car goes froward and backward .just like mixed mode. But mix mode turn off already. Can you have any
You probably have to change throttle direction on the transmitter or swap two motor wires(But NOT if it's sensored brushless motor).
Hey thanks for your video can you also make the gyro video because my gyro is not working for some reason
Hi, on the reciver there is a little button on the side, press that 3 times and then it should beep and then use the ch6 (the one on the top right) to change the sensitivity of it.
@@oskark5937 thanks alot mate I've just done my car now and it's working thanks 😊
@@dukercuk =)
good Video men can I ask which car this is?
It's a Absima ATC 3.4 (A german brand).
@@RandomloserDK Thanks man nice i got a Reely tc-04
I panicked cuz i my epa was 0 and i thought i broke my receiver wiring😅🎉❤❤
