I measured about 12.25 inches but I think trev recommends 12.5"
this 176 definitely ripped a lot harder than dales 180 on the same prop today but I think the difference is only the pipes

Those pipes Dale have are more like a canister. And a heavy ones!!!

Would like to have been there today while you flying it. Love the way they fly.

Re: The never ending engine thread, East-West

Great numbers Lorne!!

Brad really enjoyed the 32x11W on his GP on that 50lbs Ultimate but the rippage was insane like you said! The 30x13W isn't any better for rippage, LOL. The only way to prevent rip on these big motors is 3-blades or load them up, but then they suck for 3D

Re: The never ending engine thread, East-West

Also Lorne... With the 3-stage reflector cone in those Smoothpipes, the shorter you go, the stronger the top end, unlike all other pipes where there's a peak and then they fall off as you go shorter. As proof, Dave Sullivan made Kole a set of "Thunderpipes" which gives a multi-thousand RPM boost on his GP61.

The downside is midrange throttle feel goes down the tubes. I got similar numbers as you at 12", and gave some rpm up at 12.5" as recommended by Dave for the benefit of a linear midrange. Mine is like an electric in the hover range which I love. No need to do any of that nasty throttle pumping. Just set and it locks in.

Re: The never ending engine thread, East-West

I'm excited to get your impressions at 12.25". If it's really smooth I may shorten mine by 1/4" and try it

Re: The never ending engine thread, East-West

Ya, hovering throttle was fine. Pull out from a hover was strong. I just like to keep the plane a little quieter on the prop rip.
Have you tried a quiet prop such as the pt model props trevor?

Re: The never ending engine thread, East-West

I think it is fine but not quite as smooth as the planebender cans but at 500 or 600 rpm more I can deal with a tiny bit of throttle response loss. I think If I adjust the curve in the transmitter it might get close to electric response.

Jack, the slick is a kitty cat in the air. beautiful flat spin and very smooth maneuvers such as point rolls and knife edge.
