That is great since Mike has 5mm bore 32p pinions in stock. Now I just need to choose a motor. I think that a 1509 1y would be good choice or maybe the next step up in KV. That would also save me from having to go to fine design!!
I also picked up a Quark 125b on Ebay pretty cheap.

I can use it in the rustler, I am a little hesitent to use it in the 8ight-t I am building after reading all of the heat issues everyone is having. I guess I can do the heat mod though.
