I have heard that the wasp and the outlaw .26 are identical operationally speaking. The p3 has more RPM from what I hear. I'm not certain on all of this, just what I read in posts. One thing I am CERTAIN about is that the picco outlaw has gobs and gobs of power. More than this truck needs. I continue to break stuff due to the power this motor puts out. Definatively have to have a good tough drivetrain and even look at hardened steel drive cups. It goes so dang fast that when I crash, plastic suspension parts go snap. Plenty of power, I think anyway you go, you will be replacing drive parts. Cheers, and put a good aftermarket head on that new mill.
