This is a four rotor so divide everything by two.
People have trouble converting Kilo Watts to HP so
I did it. One HP is 746 watts.   

A 3:1 gear box and 
a variable pitch prop with a two rotor engine tuned
like this would realy run all the aircraft engine
racers into the ground. It would also last much 
longer than a souped up Lycoming IO-360 like 
Dave Anders is using. 

BTW his engine does not idle smoothly either :-)
