Good point, David
No, until recently the engine did not produce enough power to stall the
prop. Tracy Crook and I both agree that after rebuild of a rotary engine,
they seem to continue to improve for a considerable amount of time - Tracy
estimates around 250 hours before they stop improving. In any case, it only
happens when cold dense air is present, so had not normally had to worry
about the stalled prop.
However, your suggested procedure certainly makes sense and would not be
a bad procedure to get into the habit of. I suspect that once the aircraft
is rolling around 20-40 mph that the prop could then take more power without
stalling.
But, the LAEV prop would really be great - then I could put the additional
power to good use with a flatter pitch for take off acceleration and climb.
Oh, well.
Ed
