I had to disassemble them and use epoxy on the retainer rings though, afterwards their keep holding pretty good.
Currently I’m testing the Torqueboards 6380 motors which are the same as the 6384s 200kv from APS but with 8mm axles instead of 10mm, they will power the @kaly direct drives
Don’t get the titel wrong I still wait 2x 6374 motors, so at the moment I run dual 6384 motors.
In the last posts you can read my opinion about the motors.
If you located in the us go for the torque board 6380 ones. The 8mm shaft is more compatible with other equipment.
