Hey linc,
Seems like whenever I screw up you are there to the rescue. I will get some pics of the final set-up tomorrow for you to see and show what broke. Sent an email to Medusa to see if they are going to cover the damage. Really want to make this work now that I had it running. One thing I can't believe is the steel spur had 3 teeth snapped right off of it.

Sounds like the mesh was too tight, or something got lodged in the 2 gears and stopped them from turning very quickly... Assuming you had the mesh set right and checked it by rotating the spur and pinion manually thru a few rotations... Unless you have some severe drivetrain binding, or a diff locked up between the ring and pinion...

I do what I can to help. I honestly have very few gear related issues. I guess I am lucky, or have some idea what I am doing (mainly the 1st part!).

I heard a rumor that medusa delayed sales of the 80mm about the time of release due to some rotors coming apart.

Of course, my sources are highly trustworthy.

Don't think it was a binding problem. Just replaced both diffs as it blew one on first try. Took them apart again last night after the shaft broke and all is good. Can't say for sure if something got caught in the gears. Was only running around in the yard on grass. I set the mesh the same as I do for my nitro's. Has a little bit of play between the gears but maybe was a little tight?
What's better to use as a spur? Steel or plastic. I chewed a stock spur within seconds, that's why I went to the steel one. Just got a response from Medusa. They said they will replace the motor free of charge.
