SO does the stock engine that comes in a Nitro hammer a long threaded shaft? Im interested in buying one, and i have a 2.5 and a 2.5r laying around

And i know they have alot of power for a little .15. When my Revo was on the stock 2.5R it would wheelie like crazy! And it was very easy to tune and held tune really well. And Tower is selling the water cooling heads for the 2.5s
