f2R,

Yes, that one. It comes w/ the three bladed pro on the trainer, but I don't know if it comes with a prop at the HS, or for that matter if it comes with the flywheel. From the looks of the case, it appears to be a B.B. engine, but you know what they say about looks.
As I said, I may take it off the Trainer, and trade it with the eng. on my Aresti- if I do I'll take it apart and let you know. Might be a better idea to get a hold of H9 and ask the hard questions to them, I have been known to procrastinate
I will say it has a fairly large intake, and until I heard it was a .46, I wasn't sure it wasn't a .51 or .53! I know it's a bit strange given the amount of time I've been in the hobby (15 yrs.) but I don't have a tach, that being said, I will say this thing turns an 11X6 with great gusto! :spinnyeye
