Well the first flight couldn't have been better. This is probably my best flying autogyro. I had a nice steady breeze and the gyro was off the ground within 20 feet. It only required a couple clicks of down elevator and a couple left clicks and it was flying straight as an arrow. I did have the Co-Pilot installed but this autogyro is so stable that it really doesn't need it. In fact, with the exception of coming out of a loop or roll I couldn't tell if it were on or off.
Here are the specs. for this gyro:
Weight = 5 1/2 lbs.
Length = 52"
Engine down thrust = 4 degrees
Engine side thrust = 2 degrees right (Approx.)
Blade Radius = 24 1/2" (3 blade SG6042 profile)
Rotor head incidence = 6 degrees
Distance from prop to rotor head = 24"
Distance from thrust line to rotor head = 20"
Disc loading = 6.72 oz/sq.ft
Rotor Blade Solidity Factor = 9.7%
Engine = Saito size 70 four stroke
