450 main gear striped

[z257]

hi guys i was flying my erazor 450 today ,and it is flying great with the ga-250 assan gyro and align tail servo, but after about 5mins in on the second battery main gear was striped in a couple spots. i had a couple had landing but no crashes. do you guys no what could be the problem so i can replace it.
a guy at my field said that it might be the pinion gap between the main gear. and i have the pinion right up on the gear.
please lemmi know if you know what could be wrong.

as always thanks for the help,
zack

Sometimes it due to poor quality plastic. you can have everything setup perfect and still strip a gear.

check the pinion. The Razor is known to kill a pinion gear and causing horrible gaps and stripped gears.

alright ill replace them both. so is it normal to strip a gear every now and then?

 

[Tony]

Normal? NO! They use such soft metal that plastic is eating away at it. Just another reason to switch over to a "real" helicopter lol.

I had the "brass" pinion on my E500 wear down after upgrading parts, including main gears to xtreme. Would think that the plastic would wear before the metal. Chinese quality, again.
