I just picked one up too!

I came off a nitro hyper 8.5..... (2yrs ago)

So far I have the roller, and do not know what motor to put in either.

I am not going to be a racer by any means, but did want to mess around at a local track and parks etc. Basically, almost the same as you

I was thinkng 4s, 2650kv, and mmm unless there are better suggestions for my application.

Hopefully, someone can help us out.
