Tobias.Price Posted July 10, 2023 Share Posted July 10, 2023 hey all, after a fairly light drop my Gotway MSX seems to be inaccurately balancing. either when riding or stationary it seems to over compensate in a jerky fashion and then stop and start again 1-2 seconds on and same off. i'm very new to all this and was wondering if anyone had any ideas or suggestions it would be much appreciated. 1 Quote Link to comment Share on other sites More sharing options...
alcatraz Posted July 10, 2023 Share Posted July 10, 2023 While it doesn't completely sound like a loose control board, it's still worth ruling out. It needs to be bolted down solidly or the gyro will get weird data. It can also be a loose pedal hanger (tighten the axle nuts with loctite). It can also be a cracked shell or loose shell bolts (at the pedal hanger). Tighten them and check for cracks. Lastly in room temperature, perform a calibration. If you've recently calibrated the wheel in non room temperature it's possible erroneous gyro data was saved. 1 Quote Link to comment Share on other sites More sharing options...
Tobias.Price Posted July 11, 2023 Author Share Posted July 11, 2023 Okay. These were all really good suggestions and I really appreciate it. I have now found the issue ... The axle is broken. :'( How can I replace it and where can I get the parts? Quote Link to comment Share on other sites More sharing options...
Funky Posted July 11, 2023 Share Posted July 11, 2023 (edited) Broken how? Welds cracked, or axle itself have been broken into two separate parts? CNC new one. (If you can remove old one.. Welds..) Buy new motor. Only two options. First one will take time and DIY work. (Need to find a welder.. And CNC new axle..) Second one may cost more, but you save time.

Tobias.Price Posted July 12, 2023 Author Share Posted July 12, 2023 The axel has unfortunately sheared in two. Can anyone recommend any Australia resellers for parts? Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted July 12, 2023 Share Posted July 12, 2023 You can also try importing a new motor from China, from sites like AliExpress, if you can still find one there. In principle, any good machine shop should be able to replace the axle itself in your existing motor. Just be very careful not to damage the brittle thin hall sensor cables coming out of the motor along with the three power cables. Whether such a repair is cost-effective I don't know. Getting a new motor is probably the easier option. 1 1 Quote Link to comment Share on other sites More sharing options...
