Objet : [FlyRotary] First engine run with
Monster Prop
Temperatures were normal. After extended
runup the oil temps approached 190F and coolant temp got up to 210F this is
what I would normally see. Considering that the static rpm was the same
as my old gearbox and prop, it likely I was producing the same HP and
therefore would not expect major difference. The larger prop did not
seem to interfere with the cooling airflow - at least on the
ground.
Considering the differences in diameter and pitch between
your old and new propellers, I believe you were producing more torque at
the propeller shaft since you were turniing the same engine rpm as of old.
Congratulations on those excellent results.
Yvon.
