Geez, can't believe it's been 2.5 years since I have worked on this thing...
This is basically how it still sits, but the front axle is torn apart.
I started trying to figure out what the problem was, but never narrowed it down.
At first I thought it was a 3rd gear length issue, so I chucked it up in the lathe
and took a few thou off of it to no avail. It almost seems like maybe one of
the bearing recesses on one case half is out of alignment, but that is pretty
hard to check without a print and a CMM. Maybe Mr. Gcode can chime in,
but I already tried getting one from SDS and he does not have one
unfortunately. Another thought is a gear problem. I never got to the point
of swapping gears around, and at the time stock Berg gears were the only
ones available. Now that I have a few baggies of RCBros gears laying
around I will give that a shot too. Anyway, sorry to drop the ball on the
build, but I will get back on it now...
