(SIDESLIP) ________________________________ Message 1 _____________________________________ Time: 05:10:12 PM PST US Subject: Zenith601-List: Re: Performance take off and landings. From: "SIDESLIP" ****** UPDATE!!!!!!! Here is the flight test today. I tried EVERY combination, from full flaps to half flaps to 10 degrees of flaps. Tried holding in some elevator, and in ALL these cases, it ADDED 15-20% longer run before airborne then no flaps at all! I landed at the fore mentioned field today, with 24 degrees C, 1100' density altitude. Weighing 1100lbs. Rotax 912S with the air box. All attempts were full throttle, brakes on, then release. Best I could muster by a long shot was without flaps. It accelerates like a monster, and I was off under 1000' just. If I used the flaps, I might have had trouble. Now, the prop is a warp drive pitched for cruise. It doesn't bite in well until I'm doing 20 knots or greater, then it takes off (again, without flaps). 1100lbs, 1100' density altitude. Configuration Landing: full flaps, 60kt approach. A low 60kts. A little power on final to pull it in flat and control the airspeed and decent. Landed 500-600' to fully stopped maximum braking. Configuration Take off: no flaps at all. Hold brakes, FULL POWER, and wait for max RPM. RELEASE BRAKE, holding just enough elevator to keep the nose wheel from digging in, keeps the plane clean for fast acceleration. Rotate as soon as the airplane is ready (58kts) then rotate into ground effect for maybe 2-3 seconds. CLIMB like a homesick angel. Saw 1100'/min. It cruises with this prop at between 100-110kts comfortably. Anyways, I'm finding my take-offs around the 1000-1400' range depending on loading. My gross is 1300lbs. I was 200lbs light. Not sure what'll happen with another 180-195lbs but guessing ill still have enough space. Might find out tomorrow. Cheers for now and thanks again, Any thoughts would be greatly appreciated! I know my flight instructor said anything over 10 degrees flap on a lightly loaded Cessna 172M and it struggles like crazy to get off the ground. Odd......
