Alright, got the engine fully broken-in and it is an impressive mill! My favorite featuree of the motor is that all three needles, high low and idle are positioned on the left hand side of the motor. No more fighting to get through your linkage and adjust the low speed needle on the right hand slide barrel. The motor tunes extreamily well and is fast at the 1/2 gallon mark and pretty disgusting at the 1 gallon mark.
At the Midwest pro Series race this past weekend, I ran the Jammin JP-3 pipe, and the OPS adjustible pipe. For the money both are good pipes and run well on the engine, the OPS can be tuned in for small tracks and large tracks, where the JP3 is a compromise, but I didn't feel it hurt me on any of the high speed sections.
The best part about this motor is that it runs like a mod motor because of the work done to the sleeve and crank, yet doesn't cost like a mod. If you have seen the sister engines, OPS and Radical run, they are very impressive, and the FANTOM version comes with a standard head button to accept standard plugs. Turbo plugs seem to be slightly more finicky and for the average racer looking for a "race" engine, the standard plugs tune much easier (broader). PLUS this version of the RC Power engine is slightly cheaper than the Radical and OPS. Look for a hobby store cost of around $289.
Put it this way, I made the Expert A main in buggy with an engine that was still very tight, and it had everything I needed. I will have to be careful when it fully seats, as it can get out of control (as i saw other RC Power 'ed engine drivers run) You gotta respect the power! But its nice to have that on tap when you need it.
On the question of longevity, my engine came as tight as any other Nova mill I have ever ran. I could not turn it over by hand while holding it, with a flywheel on the crank. (I am not Heman, but you get the idea)
If you see any RC Power engines at the track, OPS, Radical, and now Fantom check them out. If anyone ahs any more questions regaring this engine, feel free to ask and i will try to answer them.
