KR> engine question -density Alt/crash
DENSITY Altitude: 2 years ago a guy at my airport put an aerovee 50-65hp on his sonex and cartwheeled it on a 3000' grass rwy after he got past V1, established ground effect, and decided to pull the plane off the ground to fly and the runway end neared. 4000hrs total time in jets primarily doesn't really fulfill the need to calculate density altitude on a historical basis. It was a humid summer 80-90F and we're only at 1000'msl elev. He had recently completed the 40hr flyoff in the 'same' weather and airport. I saw his first several flights. Even on a 3000' pavement runway, his plane did not demand air superiority on takeoff if you get my drift. It is just safer to have something stronger, and besides, running a larger engine at 70% power is better than running a small engine at 100% all the time. Krs need that weight of an engine up front anyway for CG, so do it for that. Andy
KR> Engine question
Yes, I have. Perhaps I'm oversimplifying it a bit because I have considerable experience in engine building. Still, with some experienced guidance, it's well within the capabilities of anyone who can build an airplane.

Because you climb out quicker, clear obstacles sooner, and have more altitude margin for problems that crop up...such as a dropped cylinder, detonation, flaps left down, carb heat left on (see previous "detonation"), accidental downwind takeoff, birdstrike on the prop, seized crank (my personal favorite), and a long list of other crimes that you'll probably eventually commit during your flying career. A 2180cc VW is a no-brainer, and Great Plains is the place to go for that. See http://www.greatplainsas.com/ for details... Mark Langford ML at N56ML.com website at http://www.N56ML.com

KR> Engine question
Thanks. I have never rebuilt an engine. I'm sure I will have plenty of questions. So the engines I have can be upgraded to bigger 2180? Will that be just a rebuild kit for the 2180 or will it have to be completely different?

No. My first KR2 had an 1835, and it flew well with it. However, if you could build it at 450 pounds or less, then you might get away with the 1600.

I have two vw engines that are 1500cc. I read that it can be changed to a 1600cc. Is that going to be good enough for my kr2? thank you Russell's Photography Mexico, MO 573.253-4501 http://www.russellsphotos.zenfolio.com
