These Sunnysky motors are beautifully made, but the shafts slip soo easily, but dissembling the motors and using Loctite 638 shaft retaining compound on the shafts, the motors are much more reliable. this little Tutorial should give you all the info you need as I walk you through the process.
Hopefully you can see past the vertical recording and echoing voice, I had my phone perched in a beer glass and this is the first time I've created a tutorial like this, hope it helps you, I certainly learnt a lot about making videos, next one if it's needed will be significantly better.
