6mm mod 1 pinions?

[ta_man]

I know this is a really old thread but I just ended up with a 1717 with a 6MM shaft. I found this thread while searching for 6MM shaft MOD1 pinions.

I actually found some pinions the right size and am wondering if anyone has any experience with these in an RC car used with a metal spur gear. I want to use it in a Losi 8ight-T.

A-Main has the KDE Direct pinions. One example: http://www.amainhobbies.com/product_...inion-Gear-15T

Hobby King USA has some hardened 6MM shaft pinions too. One example from eBay: http://www.ebay.com/itm/RC-Hard-One-...item3a848f6001

Anyone have any experience with these?
