RE: How many RPM,S for a Brison 3.2?
What is a NX prop, I believe you about the power band between 6200 and 7000. I relate it to a glow 90 super tiger when I read in an article its best power was 8 or 9 grand and it flew very well with a 15-8 prop. My ultimate has a wing loading of about 24 oz. a sq. foot
