I did notice a problem with the distributor on the trailing ignition
activator... the unit began to act erratically, replaced the box in the
distributor and bingo, back up to 7465 again!   (2.85 Ross on a 4 blade Warp
Drive, 745 lbs static thrust)

I called her the steroid Hummingbird!!

Gary, is that static thrust calculated or measured?  If measured, how
did you do so?

Thanks,

You can use a large calibrated garage door spring as a big fish scale.
I wrote an article in Kitplanes about it a few years ago.
Gary flies a gyro plane and static trust is the name of the game 
so to speak as they generally fly very slowly.

Focusing on static thrust is the wrong thing to do for an airplane.
It is easy to get high static thrust with low pitch and high PSRU
reduction ratios and then have the thrust dangerously drop of at 
takeoff and climb speeds as the engine revs up beyond the HP peak. We 
lost Steve Parkman in Arizona a few months ago when his airplane
(not powered by a rotary)  failed to climb out of ground effect.
