Power to Weight Ratio XEL
#1
Figuring power to weight ratio's for the R22 + solo pilot @160 lbs I get .129 HP/ Pound
The XEL's power to weigh ratio with a solo pilot @160 lbs I get .136HP/ Pound
Slightly helthier than the R22,it should be very responsive. .007 Greater
Power / Pound

The R22's engine is over rated and leaves plenty of reserve power so the Mosquito is better than equal, for a 160 lb pilot load.

The XEL's ratio goes down with pilot weight
I am under 160 lbs, but not sure how much.

Great Job John!

Wayne, souldn’t disc loading also be considered in the efficiencies calculations

Here is a little fun i had with beer math a long time ago. It shows just how efficient this little thing is.
