I'm matching up a TT61Pro with a Great Planes Revolver. I need prop recommendations please.

thanks,,

Are you going to use the stock muffler? What fuel?

I would start with maybe a 10X8 or 10X9 for speed...or an 11X7 for general sport flying.

I'll be using a pitts muffler. Fuel will be 15/20 Powermaster.

That Pitts muffler should let it breathe better than the stock (restrictive ) muffler...and with that fuel it should want to run well [8D]

You're gonna want some speed out of 'er, aye!?

START with an APC 12 x 6 and fine tune it from there.

I maidened the plane this past weekend with a 12x6. It flew fine, but I want more speed!!!!!!!

Guess I was just spittin' into the wind then...

proptop,,,nah,,it's all good. I'll give the 10x9 a try.

I know with the 3.25" spinner there won't be much blade sticking out either side, but I have a 10X8 on my WM Dago Red and it has the same size spinner...and it hauls butt

The 11X7 or 11X7.5 would work well too...maybe a little better than a 10" dia. prop what with the fixed gear on the Revolver...but I guess testing will tell for sure, aye!?

The 11x7.5 will give the best all round speed. Many pitts mufflers actualy lose RPM and less muffler pressure. The jett muffler will give you the extra umf...............The Tower 75 will be a little more money than the Jett muffler and come with a semi tuned muffler . Which won't fit a TT61 ...........

Put an Ultra Thrust muffler on it and you will pick up a thousand or more R's with an 11x7 APC. I always ran mine with this muffler and I would find it difficult to go back to the stock muffler. Try it and I guarantee you'll like it.

Oh thats right those beloved APC don't make a 11x71/2. Hey but Zinger and MAS doooooooooo!

I'm headed to the hs so lets review. I should pick up:

APC 10x8
Zinger or MAS 11x7.5

Gung, how much did the ultra thrust muffler run you?

Cruz--I think the last one I bought was $65, but that has been about 4 yrs. ago. Talk to my buddy Dave Shadel at Performance Specialties and he'll fix you up. www.pspec.com---I own at least 3 different sizes of them for different size engines. The one that fits the OS 61FX also fits the TT61 Pro. Heck I bet you increase your R's by 1500. These things flat out work. I've used them for 10 years. Never heard anyone who tried them NOT love them.

Wait -Isn't there a baffle in the TT61 muffler and when taken out gives a little more RPM and noise.............

an other thought may be a multi-pitch prop since they unload in the air I have used a zinger 12x 6-10 on an irvine 53 converted to diesel.on the pro 61 maybe an 11x6-10 may be a thought . it did give a speed increase
the there are of course other sizes that may be worth a try martin

Speedster, I'm running it with a pitts muffler.
