Mesh too tight/too lose? A spur shouldn't break while breaking in :/ My spurs last a whole season and it gets a lot more abuse during racing than during the break in process.

http://www.losi.com/Products/Feature...rodId=LOSB3570 is the replacement spur gear for the 810 and Ten T. Keep 3 or 4 in your toolbox, I am dead serious. They are only plastic, and pretty soft plastic too IMO. The gear stripped because your gear mesh was set incorrectly. It was either too loose or too tight. Both will cause a stripped spur gear. For me, I have found mine strip because of a loosened mesh that occurs during use of the vehicle. The mesh seems to back off over time from engine vibration and impact of landings on the track. I reset my mesh every time before I use my car for the day, and I still occasionally get a stripped spur gear from a gradual loosening of the mesh. You'll know right away when it happens too. Your car will barely move with throttle and you can hear a sort of high-pitched whining sound. Sometimes if you are lucky, you'll hear the whining sound before the mesh totally goes off and your spur gear is destroyed.

So to sum it all up: check your mesh EVERY TIME before you use the car, and keep a bare minimum of 3 spur gears in your toolkit. They're dirt cheap, and it ruins your day at the track if you have none left.

@ Morgoth: Are your spur gears metal? There's a huge difference between the cheap plastic spur gear that comes on the Ten T or 810 buggy, and the metal spur gear that came with my D8T kit.

Replace it with a metal gear and set the mesh correctly so theres a little more than you want with an electric 1/10.

Yea, mine is steel. I wouldn't use a plastic spur in a 1/8 buggy. There's too much flex around the spur gear and when the clutch gets hot, the plastic start to soften up.

And also Frank L's instructions, they are spot on ;-)
