Helicopters . An unbiased view about the evil things,
Getting a steady hover, week 3
The difference in stability between a helicopter and a fixed-wing aircraft is often compared to a child's swing which is hung by steel rods. If it is pushed from its normal motionless position and then left alone, the swing will sooner or later of its own accord stop exactly where it was originally. The stability of a fixed wing is similar. A helicopter, however, is like the same swing, only this time balanced upside down. If disturbed it will fall away from where it was with ever increasing speed and will never attempt to return to its original position.
To me it seems worse than that, add in what one flight simulator calls cyclic instability, the heli does not want to keep still.
Due to poor weather and the wind I had not flown my little Shogun until Saturday's evening session, this started badly with some very wobbly hovering and lots of advice not to move the sticks so much. I made some improvement, enough for the heli crowd to recommend removing the training undercarriage, this will stay for a while. I can now hover but only tail in and needing 100% concentration.
