AIRSPEEDS:

NORMAL TAKE-OFF: Don't know , never looked - I was flying. Probably going to be about 25 - 35 IAS.

NORMAL CLIMB: 45 MPH

BEST RATE OF CLIMB: 45 MPH

BEST ANGLE OF CLIMB: 45 mph

CRUISE: 45 - 60 mph

MAX MANEUVERING: 45 mph

BEST GLIDE: 45 mph

NEVER EXCEED: 65 mph, lol

NORMAL APPROACH: 45 mph

Dr. Bensen suggests at 45 mph, the Bensen blades performed at their best.

PERFORMANCE

TAKE-OFF DISTANCE TO CLEAR 50 FOOT: Too many factors to determine. Pre-rotation RPM, winds speed on your 12, thrust of engine, density altitude, etc..

On my Bensen, with a pre-rotate to 100 RRPM, and a 5 mph wind in my 12, 2 - 3 hundred feet to get airborne, get to 45 mph and start climb. robally, 800 - 1000' to clear the obstacle

FUEL AND OIL

FUEL GRADE: 100LL "only", never use auto fuel

MIXTURE FUEL/OIL: 16 oz. petro based 2 cycke oil, 14 oz of Blue Marbles to 5 Gallons 100LL

my CHT was 50 degrees cooler on synthetic and a smoother idle

USABLE GALLONS OF FUEL: "ALL OF IT!!!"

Part 103 - Ultralight = no more than 5 gallons on-board; N numbered "Registered" what ever you can feasibly build into the system

CONSUMPTION PER HOUR : On my ole 72, I could stretch about 65 minutes out of her. On my 90 - "Quiet" in 53 minutes. 5 gallon tank. Depends on power demands.
