Default thrust question

Huh?

To have a 2:1 thrust to weight ratio your engine has to have twice as much thrust as the weight of the airplane.

With just about ANY prop, that Webra is going to be more than enough to pull you out...Just get a couple 11 and 12 inch props and see what you like the most.

Chuck, I remember my Pro .46 had over 9 lbs of static thrust with the 12.25x3.75 and Tower muffler. I never did understand that. Never seemed like it when hovering the 4 lb POS...
