StanFoster Posted January 4, 2014 Report Share Posted January 4, 2014 I have enjoyed flying my Helicycle for almost 3.5 years now, and fly year round here in Illinois. My weather extremes have been from 4 degrees F to 104 degrees F. I have a laser mounted on my collective that shows exactly how many degrees of collective pitch my rotor blades are at. Typically it takes 10 degrees of collective to HIGE and 11 degrees to HOGE. The 104 degree day, I loaded my butt and full fuel just to see how it would perform. It took 11 degrees of pitch to HIGE and around 12 degrees to HOGE. It still had plenty of power and I was no wears near max TOT even flying at 110 mph in it. Well yesterday the temps were negative 15 F......and I wanted to see how it performed. I entered the following in a density altitude calculator....-15 F 30.44 barometric pressure -25 dewpoint 750 ASL......and came up with a density altitude of a negative 5000 feet! Super charged air for sure and I could sure feel it pulling my Helicycle outside. I lit the turbine and after warm up....lifted to a hover and saw my rotor blades only need 9 degrees of pitch HIGE and 10 degrees HOGE. I flew for a while and it was a very beautiful flight flying over the recent 5 inch snow we had. If you go to YouTube and look up HelicyclePilot....you will see the latest videos I have just uploaded. 2 Quote Link to comment Share on other sites More sharing options...
