 How much does it weigh ?
 
 How was the 1000 Hp determined…  ???
 
 What was the max peak torsional reversal  levels  above and below the mean
torque  during the test ? ? ?
 
 What was the frequency of the max peak torsional reversal levels during the
test???
 
 What loading condition produced the most adverse peak torsional levels with
each prop for which it is  designed to be used  and was the gear box operated
at that most adverse  condition long enough to accomplish a minimum of  10^7
peak torsional reversals fore each  engine/prop combination for which it is to
be used ???
 
 Just some of the appropriate questions that would need to be documented…
 
 Regards,  George

The guys that are developing V-8's have a problem. They either need to cam
for low RPM direct drive or use a PSRU. The Eagle 540 has a gorgeous PSRU that
will handle 1,000 HP that potentially could be a bolt-on for other V-8's. It's
compact and light. It has helical-cut gears with 3.4 tooth engagement, a huge
benefit over spur gears. Those gears have a special hollow body for lightness.
All bearings were designed by the Timken helicopter guys. It also is set up
for a prop governor and has a standard prop flange. It uses its own oil (Shell
Donax TC-50) and has its own filter and pump.
