New Catto 86" prop

I have only flown it a bit as I am doing a lot of mods this winter and my plane is in pieces.
I lost 6mph but it pulls hard, I could never slide tires on dry grass before but I can do it now at 75% throttle. :):)
Climb is about 300fpm better and the throttle response is super quick.
I should have chose an 86-37 instead of 38 I'm about 70 revs short of my 2450 static target.

Over all it is a big improvement over the 84-42 pawnee, my favorite change is the C.G. after feeling the change I am modifying the engine mount to get my empty C.G. back to 16"

I have 31s and a Riblett wing which is 1.5" thicker my plane is always a bit slower than most.
