question on a pinion problem
 

i ran my new e raze today with my mamba monster 2200kv setup and after runinng one pack i saw that the pinion was groved out where the spur was , is this normal i will try to take pics and post them

Looks like the pinion is not hardened. What brand is it? Get a RCM pinion, they are hardened.

i was not shure what it was a buddy gave it to me :)

thx
