RE: prop size
There was also a guy (P-Diddy) that was running a 17X4 on his in a showtime. Might want to look him up and see what he has to say. I broke mine in on a 16X4W APC and then used the 18x6 Xoar.

RE: prop size
Those little leaf blowers etc-- will likely never see a pipe -most likely a piece of tubing blowing straight out and mounted in a nice little sport flyer .
not like the MVVS piped , running at 9000
whatever prop is used -they work best if allowed to run 8000rpm -or more
be sure to use well selected props a lot of the crap on the market has flexible blade (s) and these can/will fly apart from even slight damage.

RE: prop size
My Brillelli 26 is running an APC 18x6W (only thing available within an hr drive) at 8720 with 12oz through it... no pipe, just a side dump muffler Will probably get treated to a pipe over the winter and a real prop just for fun.

RE: prop size
Hey, I saw my name in the previous post! I'm famous! =)
I liked using the APC 16X4W on my H9 Showtime with the BCMA SPE 26cc. The RPM's were just under 9000 once the engine was broken-in. That is about the max you would want to turn one of these. It performed very well with that set-up and those higher RPM's are good for the break-in.
You can also go with a Xoar 16X8 or 18X6 once it gets broken-in. I had a lot of extra power with those props. I don't think I ever used a 17X4, but I've never been accused of having a great memory...
