So now I'm thinking...
How do I measure the Horsepower of my Sonerai's 1835cc VW motor?
Or do I just make a couple of assumptions?
Prop 52" dia. 42" pitch motor can turn it 3000rpm static at WOT and a ground
elevation of 5000 feet and temperature of 31 degrees Celsius or 87.8 degrees
F.
Assuming that the prop is more or less efficient (guess 80%???) where does
that leave me?
