HI Bruce

The 11 1\4 x 4  Bolly cf  or  the  12 x 4.5 wide  cut to  11.5 will work very well
In a 3 blade  the Bolly  11 x 4n  pitched to 4.25 will work very well
all of these  are  on  many planes  with AT 36s  in them

I have an Aero Tiger 36 I will pairing with an ARF Vector.  What is the best choice for prop.  I have some of Randy's Bolly Clubman 10.5x5, which seem to work well.  Any other thoughts and if I go CF, what size?  Thanks to all.

    With a 10.5-5, I would guess you are running *way* down in the 4-stroke to get a decent speed. Less pitch would be what I would look for, get that baby revved up.

  You will get better performance, and better control over the performance,  with a graphite/fiberglass prop. But, if you really don't want one, I would recommend trying the APC 11.5-4. It's an excellent stunt prop (hey, I tied for 15th at the 94 NATs using one...) and I know from observation it works pretty well with the AT36.

    Of course, this kind of power in that little Vector is hyper-overkill. I've seen these airplanes fly well with as little as a Fox 35 or Fox 40 (large-case) (which, by the way, is anything, is wimpier than the 35 - certainly wimpier than a tricked-out 35)). I could fly my big airplanes, with authority,  with the 36 on a pipe. But if you get the right prop, you will not have any problems controlling it.
