I was wondering what others experience are as far as operating and flying smaller turbines at higher elevations? By smaller, I guess I am referring to the Xicoy X-45 or Kingtech K30/ K45. I fly in The Denver Colorado area which is roughly 5300 ASL. I bought a Xicoy X-45 several months ago and so far have just run it 4-5 times on the bench. So far, no issues. It starts up quickly and accelerates and de accelerates great without any problems. I have heard of others that have the Xicoy or KT that are having issues keeping these smaller turbines running at higher elevations. Just wondering what experiences others are having with these smaller turbines who fly at higher elevations. Thanks in advance for any responses. Jon
