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
Just wait until you have your first 90 degree day and you'll find out exactly what the meaning is of "Density Altitude" and why these small engines, and all others, have issues. They have the same power loss issues as any normally aspirated IC engine. 'Bout 25% at your altitude and no where near 90 degrees. It goes above that 25% very rapidly when the temps start climbing above 59 Degrees F which is a standard day temperature for aircraft/engine performance figures......
