My KR-2 is plans built. However, it has Diehl wing skins that does extend the total span by 30 inches. The wing taper is greater than stock plans. I am sure that the Horner tips and winglets also effect the MAC. The Diehl tail group probably has some extra weight beyond the stock plans. Bot

Good points. My only point is that the reference to the leading edge in the plans is for the plans built kr2...and not the kr2s. The cg in terms of % MAC is pretty consistent because it is based on the airfoil shape alone. https://sites.google.com/site/mykr2stretch/ https://sites.google.com/site

The only thing I would think you would even consider changing is to make the c.g. range in percentage of MAC only and not referenced to the leading edge, since any changes to the basic KR2 wing planform will affect the MAC...including, but not limited to...a per plans KR2S wing, extensions, winglet

(hit "send" too soon) If they got a good lawyer, he'd kept telling the jury "twenty-seven YEARS they knew about this deadly design, and they HID it from the public!" The fact that Rand died in the prototype would also look good in the tabloids, even though that had nothing to do with spins. ("T

I agree with DJ, and I think other kitplane makers do too. Recently the designer of the CX4 (an aluminum single-seat design about 10 years old), discovered the cable attachment method on the rudder was causing fatigue cracks in the rudder cables of his prototype. So he redesigned the part and ema

Making revisions to aircraft designs that have already been sold will invite law suites from predatory types. The principle that will be invoked is: You new something was wrong with your design because you made a change. Therefore, you are now admitting to some liability and must pay for your

Hi Jeff I for one am thankful for your wisdom. I am one of the great unwashed who has never completed a fully developed spin (it not being required as part of the standard PPL syllabus) so I am grateful that those who have the knowledge are happy to share with the rest of us. Many thanks Gavin M

I didn't mean writing to me or to the KR group about it. I meant someone should write to Flying Magazine about it. You sound like that person if you spin your plane and have advice on how to do it safety. This also brings up something else I've wondered about. Why have so many gross errors in the

As far as the cg range is concerned, 15% to 35% Mac is probably accurate. The problem comes with understanding what the Mac is...and from what I've seen there aren't very many krs with the same Mac. I won't calculate mine till I'm done but i guarantee it will be smaller than the plans. https://si

These aren't necessarily errors...any airplane is a flying set of compromises...you trade stability for speed...durability for lightweight. No plane is perfect. It's up to the pilot to understand these compromises. https://sites.google.com/site/mykr2stretch/ https://sites.google.com/site/mykr2str

Flying Magazine's column "Aftermath" is a detailed monthly analysis of an accident in the NTSB database. October's column is about a KR-2 that went into an unrecoverable spin in August, 2013. A great deal of info is available, because he was running a video camera that recorded the whole thing (and
