Got in a little more time on the Pro-2. My chassis is lacking two factory parts, 1) bellcrank tubes, and 2) a rear ESC mount, which actually acts as half of the rear shock tower mount. Building one of these from parts really is a PITA.
Made up some bellcrank tubes out of some aluminum standoffs.
Rear ESC tray. This is just temp as a stock unit is on the way from China ........................ with an expected delivery date of the 1st or 2nd week in April.
So while waiting for the ESC tray to print, I thought I would do a quick go-through of the trans. As I got into the diff, literally had to pry the gears out of the solid mass that used to be grease.

So yea, it is getting new parts.
I build RCs like people would have done back in the '90s ..................................... if they had 3D printers.
