I'm just happy with my choice. After talking with Russ a lot on the Ofna forums, i took the plunge and bought one of his Go's. I was on of the 1st 5 engines he sold and i couldn't be happier with the decision since the Go was the very 1st engine that I have ever bought (every nitro that I have ever owned before was a RTR).
I can't wait till this spring, I'm going to try real hard to get in more than just 4 races this season. Even with all my effort working on my buggy last year I only managed 4 races. I would like to try for once a month at least.
