Thunder Tiger 61 pro prop ?
OK...just got a new TT-61 pro for an old bipe a guy gave me. I got the 11X7 that was recommended for break-in. I have a three flights on it now. I think this might not be enough prop. What are you guys using, and what do you recommend?
as for the plane, it is an old aeromaster bipe (I think that is the name). It seems like a brick in the air! I am looking for reliable flight and decent pull around the sky. There is NO WAY this thing would think of doing precision aerobatics with the bell crank system for the ailerons. Also, as I am concerned about flutter with the inherent play in the ailerons, I am not looking for top speed. (not that one would think a bipe a speedster).

If you're willing to pay the $8 to experiment, get an APC 13x4W. They label it as a "3D Fun Fly" and charge much more than a "Sport" prop, but I really like mine.
I have the 61 Pro on a Global Right Flyer 60 and the 13x4W works great. My engine has a good low idle, but would float forever with the 11x7. The flatter prop lets it slow down for landings; I just have to learn to do them.

RE: Thunder Tiger 61 pro prop ?
I ran in my new TT 61 PRO yesterday.
The Engine appears to have the same quality as O.S. Max.
I used an OS helicopter carburetor (60K) and two different mufflers. The OS standard muffler and the Jett-Stream muffler.
Prop: 11x8 Graupner grey
Fuel: 20% Castor 80% methanol FAI mix
Plug: Enya 3
Temp: 68°F
Height: 300ft
After about 10 oz of fuel I got the following readings:
OS stock muffler: 11200 rpm
Jett-Stream muffler: 12900 rpm

In 1979, not only was I doing precision aerobatics with an Aeromaster, it was powered by a ST G60 blue head and a 12x6 prop
Rigged properly, the bellcranks works very well. Considering, in 1979, that servos cost around $35-40 each (then prices) the bellcranks were worthwhile. Yes, a far cry from what we demend of things today, but just a bit of a history lesson from the days when airplanes flew, rather than hovered [sm=sunsmiley.gif]
