Hi Andy,

Since the helicopter mechanism doesn't use the solver, you'll need to
fudge a factor that makes sense. The actual number is going to depend
in sensitive ways on the size and shape of the aircraft and will
probably be impossible to guess in practice (this, after all,

I am using this code instead the solver:
applyDragFactor(Math::pow(15.7/1000, 1/SOLVE_TWEAK));
applyLiftRatio(Math::pow(104, 1/SOLVE_TWEAK));
I took the values from the c172.
Don't include the SOLVE_TWEAK bit. That exists to slow down the
convergence of the
Hi Jim
first: thanks to everyone who helped to put this code into the
flightgear codebase.

What I have noticed is that overspeed effects don't seem to show up (negative
speed on the blades coming back should cause a stall) and if you get it up to

Very different here. The indicators on the HUD were moving and the heli
flies very calm. Did you recompile the stuff from scratch ?
That's worth a shot -- I'll try a make clean; make in SimGear and
FlightGear. I'll just confirm that it is the bo105 that everyone else
is

FWIW, I got sudden yaw oscilations as you describe for no apparent

I've no idea how to fly a heli though!!!
Nor do I, but I'd expect any strange oscillations to happen at very
low or very high airspeed, not at a medium cruise speed. I just
rebuilt
Hello David,
I will try to get the oscillations. Maybe I am able to change the
bo105.xml to avoid them.

The helicopter simulation is not finished yet. I will describe later,
which functions/ effects are totally missing or simplified.
Here it is:
Missing:

Amusingly, I'm also employed again. I wonder if there's a connection?]

I am not sure if the stabs are working correct without the solver. I
tried to use fixed values if you specify no wing and hstab, but
I've been been playing with Maik's most excellent helicopter model,
now in CVS:

I can (just barely) fly it -- I'll try hooking up my rudder pedals to
see if that makes it easier. One thing I don't understand is that I
get a lot of small, rapid fishtail oscillations, even

Indeed ! I'd say: When dreams come true ,

Very different here. The indicators on the HUD were
