RE: Prop size for Avistar with TT Pro .46?
I used a 10 x 6 to break in my OS .46 ax on a Kadet LT-40...now I use an 11 x 6
start with any of those...once flying start switching around to see what works...
several people at my field fly with 12.25 x 3.75 and love it, but I haven't tried that one yet
