Thanks Steve. I'm not so sure now. I think I was giving correct stick,
sort of, some of the time, but instead of just doing funnels, I was
doing large funnel-like circuits, if that makes any sense. So I was
doing big circular circuits, anti-clockwise, but with the heli almost
standing on its tail. I think I was anyway.. it doesn't help that I can
never remember what I was actually doing!
I increased the 'tail power' slider from 100 up to 150 (max) under the
model properties, and this helped. I also decreased the tail-fin size,
and this helped too.
But then I decided that actually, it was just me doing the wrong thing
with the sticks. I reverted the model back to normal just now, and I can
do funnels perfectly fine, but a big wide sideways circuit thing like
before results in a tail blow-out some way around. I guess this is just
normal and perhaps all I was ever doing wrong was that I was pu****ng the
heli too hard, and mistakingly thinking I *had* to push it hard just to
get a funnel going at all.
I'll play with different headspeeds too. Thanks!
