years, which should let me do a decent cut on
fan blade width and pitch, and then a rough
prediction of engine rpm and thrust at various
plane speeds. I will then do a similar estimate
for a typical piston engine prop combo that would
be suitable for an Ezee - These are all for naked

Does anybody have a power or torque curve for a normally
aspirated stock Mazda  180 HP rotary engine?

Is that the HP you have Perry?
