Paul,
Alex and Neil Varcoe, his engineer, have published the following:
PERFORMANCE DATA - Europa XS Mono w/ CAM 125 & AP3222
(Note: w/ 1 pilot and 3/4 fuel; OAT/AP unknown, however, I believe data was
taken during summer months in Pacific NW, perhaps 70-75 deg. F)
Climb @ sea level: 2000 ft/min @ 100 mph w/ fulll throttle
Climb @ 2000 ft. altitude: 1650 ft/min @ 100 mph - MAP 28", 5600 rpm
Cruise @ 3000 ft. altitude:
RPM MAP IAS (mph) Fuel Flow (US gal/hr)
4.600 16" 125 3.0
4,600 18" 132 3.6
4,600 20" 145 4.3
4,600 22" 160 5.1
4,600 24" 174 5.8
4,600 26" 185 6.6
My personal thoughts on the above data:
First, bear in mind that the source of this data is not from a couple of
hotshots eager to hype a product and set the world on fire...a common
occurance in the home-built universe.
Second, after face to face conversations, telephone calls, and numerous
email communications w/ Alex and Neil, I've come to believe that their
mating of the CAM 125 to the Europa XS has been a thoughtful and rigorous
process pursued with integrity.
Third, I take note of Alex's previous career as a test pilot for the RCAF
and hence, believe the data represents best efforts at an accurate, though
perhaps limited, representation of performance of this configuration; more
flight test data will be forthcoming.
