KR> Landing speeds
Dear Colin, If the weather is good, I fly about 3 to 4 times a week. I fly with my "other"plane out of the 1200 foot strip. I have been testing different landing techniques in preparation for the completion of my KR2. I have found that the technique that you describe, "push the stick forward to pin the aircraft on the ground, ride the bumps, I can see clearly and you balance the aircraft on brakes and rudder and slowly have to push more forward as the speed bleeds off", is the technique that I believe to be the most viable option. One reason it appears viable is that I spend less time floating and more time slowing down. A given touchdown speed gives a fairly consistent landing distance taking wind and weight as variables. I can duplicate landings consistently and so far safely. I have found that, for me, I use 70 MPH instead of your 80 MPH, 70 MPH is still a controllable speed and I only have 1200 feet. Everything else seems about the same. Thank you for sharing. I greatly appreciate everyone's input and value their opinion. This is a fantastic group. thanks, Joe On Tue, Feb 17, 2015 at 6:11 PM, colin hales via KRnet wrote: > https://www.youtube.com/watch?v=9FJuTyf2sJc > Hi all, > I've been reading the messages about landing and approach speeds.

KR> Belly Board
RE: Multi-holes drilled air brake : any good ? I just spoke to my flying buddy, Carl "Flaps" Laffert, 84, who flew both the SBD Dauntless during WW II with the Marine Corps from Mindanao. He also flew the Curtiss SB2C Helldiver. He told me the perforations create more drag. They were first used in the US on the Northrop (a Douglas division at the time) A-17, built for the Army. It had 3-section flaps, one under each wing and one in the center. These were on the bottom only, not split as on the Dauntless. The Army didn't like dive bombers so Douglas built the Dauntless for the Navy with the split dive flaps/brakes. He said the first version on the Helldiver had "smooth" flaps (as he called them) and the dive speed was 315 knots. On a later version they perforated then like on the Dauntless and at the same dive angle, the dive speed was 285 kts. Story by Ed Moorman, Shalimar Fl, 553, Former R/C Report Fun Aerobatics Columnist. 76 and up to my old tricks! Also found this; Abstract Measurements are described of the drag coefficient of porous circular cylinders (60% open-area ratio) fixed between solid hemispherical end caps, for five values of aspect ratio between 7.92 and 2.67. The Reynolds number varies between 104 and 2.6 ? 105. It is found that the drag coefficient increases with aspect ratio much as a solid cylinder's but its drag coefficient is about 20% higher (varying between 0.88 to 0.96 as the aspect ratio is increased). Flow-visualization experiments have also been conducted, and show how fluid passes through the cylinders and how the vortex shedding is weaker than for solid cylinders. Although based on a cylinder and not flat plate. Joe On Dec 25, 2014 9:54 PM, "bjoenunley" wrote: > I'm going with a solid belly board.
