AndyJones Posted February 15 Share Posted February 15 Hi there new to RC cars. Just bought a traxxas slash 4x4. It was great, and then just stopped running. The motor is turning but it’s making a high pitch whine and isn’t driving the wheels. only has it two days so called the shop and they thought it was the Slipper clutch adjustment. I’ve tried tightening it. It ran for a few minutes and then stopped again. Is there anything much advice as to what could be wrong. Apologies if I haven’t explained it very well. I don’t know all the correct terminology yet! thanks for any advice. Andy Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 15 Share Posted February 15 how odd, a lot of people say traxxas are tough and dont go wrong ha ha right the high pitch noise and motor spinning but no drive sounds like the pinion gear on the motor has worked loose you will need to take motor out to check also you will need to make sure the mesh between pinion and spur gear is set right Quote Link to comment Share on other sites More sharing options...
AndyJones Posted February 15 Author Share Posted February 15 (edited) Thanks. The pinion gear and spur gear are meshing and turning. so I think the problem is further down the chain. Edited February 15 by AndyJones Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 15 Share Posted February 15 if the model is new take it back to the shop for them to repair or replace Quote Link to comment Share on other sites More sharing options...
AndyJones Posted February 15 Author Share Posted February 15 Yep I guess I have to. It’s miles away so a bit of a pain! Thanks Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 15 Share Posted February 15 yes its a pain but better to have it sorted under warranty, if mesh is good and pinion is fixed fast makes me wonder if the diff`s have stripped as you kinda ruled out slipper clutch Quote Link to comment Share on other sites More sharing options...

Ziggy122 Posted February 15 Share Posted February 15 Follow where the drive ISNT going So if the Pinion is turning Look at the spur - then the shafts the spur turns if it Goes into a diff, is the input cup spinning but not getting a diff output Well there is the issue but if getting a wheel and nowts happening it could be a drive pin / stripped hex for example it could be a dog bones missing a CVD which has sheered in the cup upload a video even, to see if we can spot where the drive is been lost.... The slash was a monster of a basher truck, very popular... but like all cars even traxxas, something does break The rustler for example was a swine for Sheering the differential input gear pin meaning the drive entered the gearbox but didn't come out it was spinning the shaft inside the 1st gear.... This hobby, things break Getting your fingers in there and finding out what's wrong is great way to really know your truck!! ziggy 1 Quote Link to comment Share on other sites More sharing options...

Is the pinion rotating the motor though? It's very likely to be a loose/lost grub screw somewhere, so maybe on the pinion or another shaft. Happens with just about any RC so it's good practice whenever buy an RC to go through it all and locktight all screws which are into metal threads.
