What pinion?
 

I'm getting the 8xl for a hyper 7 conversion, but I don't know what pinion to get. Any help would be apreciated.

Whats the tooth count on the spur and whats the gear ratio on the diffs? Also, how many cells?

I don't know, probably stock. It's the pro kit also. I think the rear diffs are stripped, do you know where to get replacements?

Either mike or Towerhobbies will have it probably. I can find out what it came with but how many cells? And what spur? Is the spur steel or plastic?

It'll be 12 cells with a steel spur. 42 tooth I believe.

Then a hardened pinion is required. I would say a 13 would be about right.

what pitch?

Mod1.

Thanks for all your help!

Btw can you get them anywhere for cheaper than $25? That seems waaay too high for a little hunk of steel... I was right at my budget without it and I don't get money very fast these days...

Nope. Mike is pretty much the only person that has them.

That sux.. Wont be able to get this thing running for another 2 months!

2 MONTHS!! I'm sure you can sell something or something along those lines...

Yeah, I can sell something, but I'd rather not. I get monthly paychecks, and I'll have $300 at the end of this month. That's enough for the brushless setup, battery straps, motor mount, and connector plugs. Then I'll have to wait another month to get my next paycheck to pay for the pinion as well.. ugh...

Would this work?

Its not hardened. You have to have hardened pinions. I believe those are actually the same ones Mike has but I'm not sure. If you resort to a standard pinion you need a plastic spur for your center diff.

the guy here used that pinion with a steel spur and didn't mention anything wrong. We'll see though, I've got 2 months to make a descision. :027:

that's because it was hardened...
