RE: PAW .06 props?
7x3 is a good size. I've been flying my PAW .061 a bunch lately. I use my "Baker Black Brew" mix: see the tested fules thread...
Actually I've been sanding my prop down a little and if they made a 6.5 x 3 I would give it a try but they don't make one. 6x3 would be too small I think.
