1 I'm an helicopter pilot ( choppers are very sensitive in all axes) 2 Offset, I' ve about 2° right and 1° down engine
3 big prop dia. about 73" ( max rpm prop. of Rotax 912 is 2400 ) 4 C.G. at 22% Wing chord , in flight test, and max rear C.G. of 27% 5 12" longer fuselage , from the spinner to the tail I've the same lenght of a KR2S ....................................................... Thanks Franco. My particular interest is focussed on the flight characteristics of the KR2 /KR2S, with particular reference to the incidence set-up incl. the thrust line and CG. Larry Flesner has been reporting on his airplane and the results are very interesting (to me). Larry's lady has an 18" stretch and is almost stock in terms of rigging - 3.5 degrees positive at the root, 3 degrees washout and the stab at zero. He has not checked, but almost sure his thrustline is zero /zero. His airctaft requires modest up-trim in the cruise (approx. 140mph) with a near neutral CG and something under MAUW. His aircraft demonstrates the classic KR nose down sit in the cruise and returns an immediate (gentle) down pitch when the thrust component is removed. Next we will talk him into establishing the hands-off glide speed with the cruise trim setting. For this reason I was happy to see your email - when you get a chance, please give us some more info (modifications, decaulage /indidence, washout etc. Steve J
