| SCX24 Reverse slowdown issue?
I've been lurking a bit here before finally deciding to get back into the hobby and I wound up grabbing a SCX24 C10 in teal. I've got a bunch of ideas for this little guy, but after owning it for a week, a problem has started occurring. After a few minutes of driving it around (during which, it behaves normally), it will start acting peculiar. When reversing, it starts at normal speed, but will slow down, as if I'm laying off of the reverse throttle control. After a bit of that, it doesn't just slow down, it lurches. Forward is not affected in any way, only reverse. I attempted to diagnose the problem myself, first by removing the front and rear axles and testing both by spinning the end of the drive shaft, first one way and then another, and neither of them hang up at all, they're buttery smooth. I'm starting to think either the motor or the ESC/Receiver is the issue, but before pursuing warranty replacement bits, I thought I'd see if anyone else has dealt with this type of issue, and if so, how they solved it. (I did spot another thread about a similar issue, but as it wasn't quite the same situation, I thought another thread would be useful.) |

I only run mine in H speed position (provides full power and speed when needed and modulated by my finger) and not a problem atm. Sounds like you've done a great basic troubleshooting. I've read of some peeps servo caused ESC issues, I'd unplug the steering servo and drive it forward and reverse see if there's any difference. Also move the transmitter L/M/H speed switch back and forth several times through all the settings and back to where you like it, could be a dirty/bad connection inside that adjustment switch and moving it around can help clean it up for better contact.

Thanks for the suggestion, Natedog. I've tried each of the L-M-H settings and the problem persisted with them all, so I went ahead and got in touch with customer support/warranty services. I have to say I'm impressed with how they handle things. They agree that the problem seems to be either in the motor itself or the ESC/RX, so they sent one of each to me. I'm going to try one and then the other just to see which of them is the source of the problem, then report back just so others might not have to go digging as far as I have. I'll be honest, I enjoy the act of tearing down and rebuilding almost as much as I like actually driving these things. |

Did you receive the replacement and have you tested it to confirm that was the issue? I have the same issue. Thanks. |

I'm having similar issues with my C10 SCX24. Honestly I've had a lot of issues with these. I bought 3 of them about two months ago, 2 Deadbolts and the C10. The first Deadbolt throttle stopped responding 3 days in. The C10 throttle did the same thing about 3 days in as well. Steering continued to work fine on both. Second Deadbolt started driving super slow 3 or 4 days after I got it. Ended up going through the warranty process for all 3 trucks and sent them back to Axial. Axial replaced one Deadbolt completely because it needed a new transmission and they were back ordered. They replaced the motors in the C10 and 2nd Deadbolt and sent those back. Servo has gone out in the 1st Deadbolt already in about 2 days, C10 still running but doing the slow reverse thing mentioned above, and 2nd Deadbolt has repeated the issue with the throttle stopping responding. So basically that is 6 trucks that all broke less than 5 days after receiving, and they aren't being abused at all. I want to try and replace the motors / servos and maybe the ESCs to see if I can get them working again on a reliable basis but need some suggestions for the best parts to get. Unfortunately I don't have hours and hours to search through the forums, Amazon and hobby websites trying to track down the right parts and the stock Axial parts are obviously worthless.

SaVox 0257 servo has been great for me. A little expensive though. A lot of people are using the Emax es08 servo cheaper than SaVox but still works well. Dynamite barrage 1/24 motor for a replacement. You’ll have to drill holes in the motor plate for it to work. The mounting screws are in the opposite sides. Or you can order a new mounting plate from Shapeways. Sent from my iPhone using Tapatalk |
