MiltonFarb 4 Posted August 21, 2019 Hi All, I've recently bought a Super HotShot so my son and I can enjoying building the car and i can relive my childhood.The build has been progressing well and we've got to the bit where we fit the electronics and this is where we have hit a problem We dry fitted everything and tested that the servo drove the steering which worked fine. However when we then connect the motor we get a high pitched beep any time we try and hit forwards/reverse on the controller, but the steering still works We are using the Tamiya TBLE-02S and have checked we have the wiring correct to the motor from the ESC so any hints or tips appreciated.

Winniez 8 Posted August 21, 2019 See what the LED on the speed controller does (blinks, how much in what colour etc.) and then refer to the manual. Usually they have a cause/symptom chart at the back. And try to take the motor out of the car (maybe the gear mesh is too tight) and see if it does the same.

MiltonFarb 4 Posted August 22, 2019 Thanks - we've done a lot of trouble shooting last night with the ESC and it does suggest its programmed correctly. The one thing we did do was remove the motor and realised that it doesnt turn manually and wondered if its the motor thats causing the issue. I'm just waiting to hear back from the store we bought it from Share this post Link to post Share on other sites

I'm just waiting to hear back from the store we bought it from If you can't turn the pinion by hand at all then it's worth quickly checking that a stray screw hasn't been pulled into one of the motor ventilation holes by the motor's magnets, and is now jamming it up. For ESC configuration it needs to be brushed not brushless (you can tell which it's set to from the colour of the LED when you switch it on I think?). And it needs to be the right 2 of the 3 wires that you've plugged in - can be confusing as the car's manual normally talks about the wire colours assuming a brushed-only ESC which only has 2 wires, but the TBLE-02S can do brushed or brushless, but the wire colours are the standard brushless colours. When connecting up the motor, go with the wire colouring for brushed mode in the TBLE-02S instruction sheet, and not the wire colouring in the car's build manual.

Sickpup 10 Posted August 22, 2019 Its funny you mention the motor doesn't turn. The one in my Supershot is very tight, I bought it second hand and assumed it had the gearbox assembled incorrectly but no it turned out the mototr was incredibly tight so I can see it being a tight motor.

MiltonFarb 4 Posted August 23, 2019 Thanks for all the advice - we found that a washer had got pulled into the motor and was causing the issue. Now to fix the next challenge - we have the motor spinning but no drive - so some more investigations tonight Share this post Link to post Share on other sites
