Eduardo, Most of the time I fly from an elevation of 444 feet but I will throw out some numbers and others can dispute or refine them. For a KR in the 650 to 700 pound range you will want an engine producing at least 75 to 80 h.p. for good take off performance. You could use a turbo to normalize a smaller displacement engine or start with a larger engine that will still produce that h.p. at the 21 or 22 inches of M.P. you will have at 8000 or 9000 feet. I'm assuming that is you field elevation from an earlier post by another builder. Perhaps a Lycombing 0-235 or 0-290 or the Continental i0-240 but these are all rather expensive. The Rotax 914 ( I think it's turboed) or the Jabaru 6 cylinder of 120 h.p. may be good options also. There are engines out there. It depends more on you financial resources then engine availability. Perhaps Jeff Scott could offer some advise as he flies from high altitude. Good Luck. Larry Flesner
