How good are these new fangled 'three axis gyros' fitted to the new generation helicopters?
3d flyers seem to really like them - but then 3d flyers are the Gods of the helicopter world; with 20:20 vision, the reflexes of a panther. and an innate ability to 'read' what the helicopter is about to do!
3d flyers talk about the 'locked in' feel these gyros give the helicopter. But actually 'locked in' means 'adheres to the pilot selected flight path'. What I am missing when I am twiddling a 3 axis gyro driven helicopter, is the ability of a more basic machine to 'sort itself out'. (In other words - for the helicopter ignore the idiot with the transmitter)!
Is there a half way house that can smooth the transition from fixed pitch, into collective pitch (3 axis hot-rod)?
OK, I know we can add a bit of exponential, and a bit of dual rate, to calm things down a bit. But I am wondering about adding a bit of airframe stability.
Idea one; experimentation with non 3d, flexible, or flat bottomed blades. The expectation being that a flexible blade will take on a more pronounced coning angle whilst flying; so that the helicopter will tend to want to 'sit in the bowl'. The bent up blade tips, a la Walkera CB100 giving the helicopter an extra touch of self centering stability.
Idea two; how about a 10 or 15 % increase in mast height? The idea here being to increase pendulum stability. Not what a 3d-er wants, but for mere mortals, it could be quite pleasant. I am not talking about the exaggerated mast heights that we were used to when flying CX2's etc, but an extra 20mm on a MCPx say.
Any thoughts guys? Before I start wasting too much of my time and money.
p.s.
What do you mean Mike? Female is a mistake!
