Re: KR> Mods for preventing flat spins in the kr

A "steep vertical descent" doesn't sound like controlled flight into terrain (rising or otherwise) to me. On 17 October 2017 at 12:50, Kayak via KRnet wrote: > https://www.wired.com/2017/05/icon-a5-crash-kills-2- > including-unique-planes-lead-engineer/ > > > On Sun, Oct 15, 2017 at 11:50 PM, la

Re: KR> Mods for preventing flat spins in the kr

Fair enough. The similarity between the model and the kr is too much to ignore though. What works for the model will most probably work for the kr. Tail design no 2 from the paper seems most promising. The rudder is cut off below the elevator and that increases the yaw damping moment. A bigger

Re: KR> Mods for preventing flat spins in the kr

Of course. Aft cg is dangerous. The paper shows that some designs are just prone to flat spins even with forward cg. The KR is safe if you handle it correctly. Push it and it will bite. Hey it makes all you KR cowboys look macho! You been flying the KR safely for a long time and that is an asto

Re: KR> Mods for preventing flat spins in the kr

I am glad I did not have the Internet with all this information when I got my KR flying in 92. I’m not sure if I would have ever flown it. Instead I put 800 hours on it before I sold it and had a blast. Loaded aft CG with my wife 5 gallons of fuel and an overnight bag all behind the seat, stick

Re: KR> Mods for preventing flat spins in the kr

RogeIio...I recall the Tiger Moth had spin problems -years ago- and they fixed it by fitting a short flat platform on the fuselage top directly in front of the tail . Sounds familiar ! V

Re: KR> Mods for preventing flat spins in the kr

Flat spins often have much to do with cg. Sometimes cg issues will not allow recovery from a flat spin no matter what the vertical tail is shaped like. On Oct 14, 2017, at 9:00 AM, krnet-requ...@list.krnet.org wrote: Message: 2 Date: Sat, 14 Oct 2017 10:34:14 +0100 From: Rogelio Serrano mailto:

KR> Mods for preventing flat spins in the kr

According to nasa technical paper 1009. The kr tail is the worst design for spin recovery. The combination A flat bottom and rounded top tail and the position of the horizontal stab relative to the vertical stab is just the right combination to go into a flat spin. Apparently just rounding the
