This rotary breaks all the rules but has managed to acquire 
450 flight hours. The six blade warp drive prop
probably provides very good static thrust with 
the 2.85:1 Ross PSRU. Not too good however at 
higher speeds.

The intake system and exhaust system is un-sofisticated and 
untuned so the power is modest. Nitrous oxide is used to
get the heavy 2600 pound airplane unstuck from the water.
When more cooling is needed another radiator is merely tacked
on where ever and sans ducting.

With a few engineered improvements like induction tuning
and ducted radiators  I am quite sure the performance would 
be greatly improved.
