RE: Thrust Figures For Norvel .049 and .061
Nick,
I'd have to say it depends... I'm running a cox 5x3 "rubber ducky" on my .061 and getting about 17oz. I'm using 35% Norvel fuel with the oil brought up to about 22% The rpms get up to 22k static. Probably close to 25k dynamic. Needless to say, my delta screams!
With the same combo the .049 would get about 13-14oz thrust.
