Fw 190V-18/U-1 shakes at idle
Jorg Sparbrodt's FM update has the lower M.O.I. entries (which I use as the FM), but when I try to reduce the amounts on all four M.O.I. entries... The plane shakes on the ground.
What amounts should I use?
And on a side note... could someone make a better FM for the aforementioned plane?
Optional Replacement FM for Ito's FW-190V18
Optional Replacement Flight Model for Kazunori Ito's FW-190V18
NOTE: I also included a replacement panel.cfg for those of you who are using the original Ito panel. This simply adds a
view adjustment to see better over the 2D and VC panels.

Notes:
I completely redid the flight model as the original was not a good starting point. However, I only invested about 10-12
hours in this so it is not perfect and could use some tweaking in various areas.
1) I converted the tail wheel to castoring as the handling is much improved that way. If however you do not have pedals or
wheel brakes you can convert it back to fixed by changing the Contact Point.0 parameter 180 to 40.
2) Speeds at altitudes are acceptably in the ball park for me using GPS Groundspeeds or AFSD as a guide. She will climb out
at 2500 fpm to about 6-8000' and then reduce to 2000 fpm until speed decays to 140kias, then reduce by 500 fpm as necessary
in your climbout to FL350. (The real world climb was at 2987 fpm but I reduced that slightly.)
3) For takeoff, use a few degrees of up trim, no flaps required and pull her off around 95kias.
4) Landings can be bouncy if you land too fast. Slow your speed to 90 kias or less before your easy flare and allow the aircraft
to sink just above stall speed to a 3-point landing.
5) The FS Reference point for this model is about in the pilot's lap rather than at the CoG. I could not change that fact
as it's built in to the model. As a result, tight turns look a little strange with the pivot point being behind the main
gear rather than at the tires.
6) I am not pleased with the AoA at some speeds but improving on that would take more time than I have to give it. There are
other issues that could be improved upon like drag, pitch due to flaps and gear not spot on, some jitters when starting the
roll, etc. But what I have here is certainly flyable and enjoyable at least on my rig with my control sensitivities.
If anyone wants to improve on this base FM, please feel free to do so.
I hope this is an improvement over what you are using but be sure to keep a copy of your original.
