Well another minor annoyance. Yesterday ran the short course truck again to confirm all is well with the new electronic speed controller. So ill start by stating the obvious. To swap one out, its a couple mounting screws, a few wires to un plug (or plug out if you are irish, asked an irish bloke once why they say that, his answer was out is the opposite of in) reverse the process and jobs a gooden. Nothing remotely mechanical.
Second test run. Thing turned on fine, fans were on. It went 3 feet, motor revved to the max whilst the thing coasted to a stop. No drive. My instant thought was the grub screw on the pinion backed out, thats not uncommon. Before removing the gear cover i noticed the motor had not shifted, so not a gear mesh issue, had to be the pinion. Nah wasnt the pinion, the spur gear was completely stripped. So i never had that issue when i was running slipper clutches as i had a steel spur gear. Main issue with slipper clutches is they are fragile, or atleast i broke a couple. So i have a much stronger centre diff in place of the slipper clutch. Diffs fine, but im yet to find a steel spur to fit the diff. Theyre different to the ones for the poxy clutch setups.
Not the end of the world. Whilst i had a nylon 50t spur in it, the one it munched, and not a spare 50t. I did swap in the spare 52t i had. I did order a couple 50s for it. The way things work out for me is order 2 you'll only ever need 1. And theyre only $8 each.
