After quite a summer of enjoying the stock setup for a Losi 22S SCT, I decided to mess around with the gearing.
And things have gone sideways quickly.
The objective was go get more speed with a change to the pinion & spur gears.
Stock Pinion: 48p, 14t
Stock Spur: 48p, 84t
I changed those out to Losi branded parts:
Pinion: 16t
Spur: 81t* (TLR Part TLR232078)
*My first attempt was to change the spur to a 78t (TLR 232010), but that didn't work because the motor mount prevented the gears from touching, let alone meshing.
After a single session on a dirt track that seemed to go great, the next time out within minutes the spur gear was toast.
Oops.
I can only speculate what went wrong. Did I not screw the motor back to the motor mount tightly enough resulting in a loose mesh and thrashing the spur gear? That wasn't immediately evident.
The pinion gear is still in place - no glaring problem there either.
I looking for feedback as to what I may have done wrong. At the same time, I am trying to locate a metal spur gear that might work with the (Brushed) 22S SCT. That search hasn't proven fruitful yet. Anyone know where I might find a solution for a metal spur gear? There is a slipper setup currently...not sure if that will require additional changes at this point.
So - How badly did I F up? Where should I go from here?
Thanks!
