I just arrived home after flying with Mark L. and spending a couple days with his family due to bad weather. I left Huntsville with 15 gallons of fuel (90 lbs) and baggage (75 lbs) and my daughter (60 lbs) and we climbed out at 1500 '/min at 110mph. Once we got into a broken cloud area we climbed to 13,000 and flew above weather until south of Columbus where there was a line of storms we could not get over ( no oxygen on board) so we went under and around them and finally passed them and made it home. No problems climbing or taking off and I do it a lot with full fuel on long trips - thats 33 gallons (198 lbs) and my daughter and fuel - that puts me at 1250 lbs. When it is just me and less fuel this thing climbs like a homesick angel. I do prefer my Corvair 2700 over the 2180 turbo I had in my other KR. This climbs better at gross than the other did empty. You do need to remember that with the higher gross that the G rating would be less than published but I try to keep mine under 3 Gs max - for comfort. Build the gear to handle the higher loads - dont forget the tailwheel either because I have bent mine a couple times. For the money I would take the Corvair over the O200 anyday. I can build up a couple spares for the money. Just study the manual from WW and listen to those who are currently flying for info. There will soon be enough stuff out for a basic firewall forward kit for the KR2S very soon. Keep you posted. Bill N41768.
