Reverse stopped working.

[7car7]

I have a truck that stopped going in reverse.

Any ideas?

The "brake" function still works.
I swapped in another motor (just hooked up the wires and held the motor), and that other motor also does not give reverse.

The ESC blinks red when applying reverse, but no action.

I checked the trim, and in one direction, the motor starts going forward of course, and turning it the other way, the red light will blink, and then turning the trim further, will come on solid.

i would start by recalibrating the esc to the controler. maybe read the manual an see if it has reverse lock out might just b the problem if neither of these fix it may b time for a new esc

Recalibrate to controller. Can you elaborate on that procedure please?

ESC is HPI SC-15. The old kind. Not the latest waterproof one - that supposedly has re-program instructions according to others on other forums. Yet no one can produce those instructions.

Here's the HPI pdf manual for a truck that has the Water Proof ESC...

i didnt see any where in the manual on how to calibrate the esc to the controler.it dose talk bout the fail safe ill look n see if i can find more info on it


ok looked around an this seems to b a common problem accordin to some it is auto setup an has no program functions if this is the case sounds like time for a new one

I think you are probably right. Time to shop.

Anybody have one they took out to do a brushless swap?

I may have a solution. I'll find out this evening.

From another thread that I finally stumbled on....

Hold trigger with radio turned on and turn on ESC. Lights will flash. Go to neutral for maybe a second. Then go to full reverse for maybe a second. Return to neutral and it will make some beeps, lights will stop flashing, and mine at least was calibrated. This seems to be something that has to be done within a time limit, more so than it is reacting to the end points.

I think a family member may have turned this one on, and not being an RC person, may have had their finger on the trigger. We'll see....

yea ive got a castle sidewinder sct an thats how u calibrate it to conttoler worth a try i yook my stock brushed setup out day after i bought it had a junk esc from factory hpi replaced it but i went brushless

Sadly, I could not get it to fix itself doing the throttle on then turn on deal. I found that if I tried holding the trigger, then neutral, it would put it into a mode that kept part throttle on in neutral, and full with throttle, and brake when pushed forward. I guess that's race mode?

Anyway, still no reverse. I'm beginning to think it may just be the ESC.

I did get a response from HPI finally, and they attached the user manual for the newer water proof version. SC-15WP. Unfortunately, it's completely different. That newer one has a mode button for programing, mine does not. The menus are then of course not compatible with mine. Hoping they can send something for the old one - my manual has no programing at all.
