? ? >>What about changing the location of the cg range, or should I stay with RR >>location?
>If I remember correctly, the Diehl skin instructions don't call out a change in CG location over the KR2 plans, even though the wing planform changes a bit (just taper and length, I think). Same with the KR2S...still 8"-16" aft of the stub wing leading edge. >I didn't answer your question the first time because I couldn't figure out what you meant by "With those, the leading edge of the wing is 11.5" fwd of the front spar face, and 1.5" fwd of RR plans". The plans simply say "CG range is 15%-35% of wing chord, 8"-16" aft of the inboard leading edge." Yes...I know that math doesn't quite work out. But I would just stick with that, given no other information to the contrary, with the exception that I'd call it 8"-14" for reasons we all know...the aft 2" is not a pleasant place, if not just plane unstable. >Mark Langford, Harvest, AL >ML "at" N56ML.com >www.N56ML.com[http://www.N56ML.com] I was also a bit confused by the comment about moving the leading edge. To the best of my memory, it didn't change from the plans built to the Diehl wings. I have the Diehl skins on my plane and used the shortened version of the RR CG of 8 - 14" for CG. My KR is balanced such that with the worst case fwd loading it takes a minimum of a 110# pilot to get the plane in the FWD end of the CG envelope. With the worst case aft loading of fuel, passenger and baggage loading, short of hauling lead ingots in the baggage area, the plane will go well over gross before I can get it out of the aft CG. -Jeff Scott Los Alamos, NM
