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.
