Wow guys thanks for the info what I like to see

Actually I know who the support person is, his name is charlie which is the man dude there and been there for ages so im surprised and the kinda lacking support I got in his replies, no offer for a replacement pinion and obviously bad info. So Robinson gets my money then, I have a 17t coming and so far the 15t novak thats on the truck now is holding up better then the 16t lol, once I get more funds I will maybe pick up a 16t rrp, right now with a 47 spur it seems pretty undergeared its not getting hot at all, why I grabbed a 17t to see how that does.
I got my new true rc lipo yesterday also, nice pack (4s 5000mah). Hoping come tax time I can pick up the 8000mah next, I will get some pics once I get the braces put in, I was reading a older post and saw how the guy made a really nice stop but I forget who it was sorry I will look it up again to give credit :)
One other thing I went ahead picked up a new 2 speed tranny with the HD gear to give it a try I think with a 4s a shifting tranny can be done and the same thread I was reading about the brace he was using the 3spd with no issues and many runs, think you guys with the 6s are the main ones having issues haha for me im plenty happy with the 4s power.
