Hey thanks for looking... I have the brushed edition and after setting the gear mesh which i have done successfully about 6 times, 6 minutes into my first run i hear a gear slipping problem so I stop the car and remove the gear mesh cover. Then I see the gears are getting knicked or worn wrong (not stripped) so Im sure the gear mesh was off. So I take it apart again and if feels like the shaft that the spur gear is loose. - actually the whole shaft moves if your grabbing at the clutch nut there. Not exactly super loose but not tight enough where you want yer gears lovin life... Thats my main questions is how loose should that shaft be ?
If it is bent or loose, you might have a bearing issue
