Hi. I've been working on my first build - Axial scx10ii and all seemed to be looking and going fairly well. I hooked up the motor the other day and it wouldn't turn. ESC is fine. It seems to be an issue with all the small gears... I've taken it apart and tried to rebuild it multiple times. It seems when I go to put the cover on the transmission they stop turning freely. Without the cover, I can get them to spin. I'm not sure if I'm explaining it right. I think my issue is kind of around step 20 in the manual. Not sure what's happening or why. Any advice is appreciated. I tried to google the issue but without knowing all the proper names etc it's been difficult finding any sort of leads or answers. I've also never posted on a forum ever so not sure if I'm even doing this right!!! Thanks for any hints and tips!
