im guessing your not letting off the throttle when landing ?
or your gear mesh is to tight .

i run a associated rc8te and only went though one plastic spur from wear it did not strip though.

Had the same issue with my 2200kv. Never did find out what exactly was the issue though. After two I went to the forums, YouTube and google for help.

1) check YouTube on how to mesh gears on rc. Most use a dollar or paper in-between the gears and then tighten it. Not saying u don't know that bit of info but if not try it.
2)nxt I went to the castle link program and lowered and tested most of the features like the motor timing, start power, throttle control and torq amount. It took a while but I started with all of them on low and torq control on level 5 for power(not sure what the setting name is on the torque control, link isn't open in front of me). I used my laptop and not field link. After a few timed runs I bump up most of the settings till it was just right.

I'm not sure if the stock settings are too much torq or what but after all that I stopped going through them. Hope that helps.

There's a really simple fix for this, it's called a metal spur gear I got one from Losi Parts house and it worked wonders. Been running it over a years now. Sure I eat through a pinion every few months, but no biggy, it's a heck of a lot easier to change a pinion gear than it is to change a spur. Make sure you keep the mesh loose. Mod 1 likes a loose mesh. Not so loose that they barely touch, but much looser than you'd run in a vehicle that uses 32 pitch or 48 pitch that's for sure.

I disagree.

Run the mesh as tight as you can, and it still has a little backlash. To loose mesh will get you a stripped spur. The Losi motor mount can handle a tight mesh, since motor and center diff flex together.

I've blown a few spur gear, two from not using locktite and the motor moved, and one from casing a jump with full power.

If the motor can't move and you watch your throttle when landing, a plastic spur cab last a long time.

Then I guess we'll agree to disagree I blew many spurs, to the point where it was really hindering my driving because I had to be so careful about waiting to get back on throttle after landing a jump that it was slowing me down. Losing 1/10's a jump adds up quickly and can end up costing you a second a lap. Depending on track size, that could cost you a full lap by the end of the race. I tried everything, tighter mesh, loose mesh, "just right" mesh, I still was stripping them even with brand new pinions. I put in a metal spur gear and have simply made chewed up spurs a thing of the past. Metal spurs on this car when meshed right aren't even loud the way some other cars are. People rarely even know I'm running a metal spur. I have the plastic spur in my SCTE which also uses mod 1 gears. the 1/8th scale cars just have too much power for the plastic to be reliable in my opinion. The SCTE has a lot less power so it's easier on gears and the plastic spur is fine for it. That's my $.02
