DamageHigh Posted May 22, 2022 Share Posted May 22, 2022 Hello,I'm new to RC cars and I bought my first "serious" RC truck, it's JLB Cheetah 120A. I ordered the RC from Banggood and when it arrived during the first run I noticed there is a second delay on the throttle, brake and steering. I reported it immediately to Banggood and support doesn't care, after months of fighting with Banggood customer support I gave up. First it was just a second delay what ever I pressed on the Remote control and then with time it got worse to the point RC is completely uncontrollable and dangerous (see the video). When I turn on Remote and then RC somethimes it doesn't connect, so I have to turn it off and turn it on again, when it connects it steers to the full left and gives max trottle, when I press brake or anything else on remote it doesn't react at all. I want to fix it, so far I tried -1 - Replacing Remote Control and receiver I bought Dumbo 6 channel remote with X6FG receiver - it did not fix the problem2 - I reprogrammed the ESC to the default settings - no luck3 - Calibrate neutral, trottle and brake point to ESC - again no luckAfter all those attempts RC just steers to full left and gives itself max trottle, it doesn't react to anything. As you can see videos are posted last year in September, couple of days ago I took it from strorage and nothing changed, when I turn it on it steers to the left and gives full trottle. Now I suspect the ESC is the problem, but before buying anything I want to hear from experienced RC enthusiast what they would recommend.Thank you for the help Quote Link to comment Share on other sites More sharing options...
Tug Posted May 22, 2022 Share Posted May 22, 2022 Try unplugging the servo, then turn on. It's not unusual for dodgy servos to cause Rx issues. 1 Quote Link to comment Share on other sites More sharing options...

DamageHigh Posted May 22, 2022 Author Share Posted May 22, 2022 I unplugged everything from the receiver except ESC (Channel 1) and again it gives full trottle. Quote Link to comment Share on other sites More sharing options...
Tug Posted May 22, 2022 Share Posted May 22, 2022 Have you calibrated correctly? Via the manual? Quote Link to comment Share on other sites More sharing options...
DamageHigh Posted May 22, 2022 Author Share Posted May 22, 2022 I did not use the manual, I watched the video on YouTube. Quote Link to comment Share on other sites More sharing options...

Nitroholic Posted May 22, 2022 Share Posted May 22, 2022 steering is usually channel 1.... When its running l;ike in the video, did you try operating the steering on the transmitter? 1 Quote Link to comment Share on other sites More sharing options...
DamageHigh Posted May 22, 2022 Author Share Posted May 22, 2022 I did but it doesn’t react to anything - brake, trottle, left and right steering, nothing is working. And the car gives itself full trottle and steers to left when it’s connected to the remote, if it’s not connected it will not do that.

DamageHigh Posted May 23, 2022 Author Share Posted May 23, 2022 Progress! I recalibrated Remote control and not steering and trottle works, brake seems to word as well, but reverse doesn’t work… Quote Link to comment Share on other sites More sharing options...
DamageHigh Posted May 23, 2022 Author Share Posted May 23, 2022 False alarm, it’s uncontrollable again for no reason. I tried again bidding receiver, calibrated remote and checked ESC programming and everything seems to be ok, but RC refuses to work, same symptoms as before… Quote Link to comment Share on other sites More sharing options...
