Saito 91 on showtime 50 at about 6.5lbs.

Wondering if static thrust is equal...or just about.... is there a benefit to the higher rpm range?

So far ive run:

an apc 14x7 at 9000 rpm(calculated 9.77 lbs of thrust) ,,,

and 15x6 xoar at 8400 rpm(calculated 11.22 lbs of thrust)


also wondering if i should be looking for higher peak rpm - am i putting too much load on engine with 15x6?
