View Full Version : Pitch stickiness

06-21-2001, 06:36 PM
I have written an airfile FS2000 Curtis Jenny, mostly from scratch and
consulting other airfiles. I intend to use it with Bill Lyons excellent visual
model from GW2000.

I remain with a problem of pitch "stickiness". While flying straight and
level, it seems to show the amount of pitch drift I would expect. However,
once it gets a few degrees off level (up or down) it will never return to level
without HUGE control imput.

For instance, if I am flying straight and level at 4000 with full throttle, and
I move the throttle to 50%. I would expect the plane to decelerate, nose over,
gain some airspeed then the nose would start coming back up. In this plane
however, it will nose over and stay that way until the wings come off.
Applying full throttle does not help, it still points at the same spot on the
ground. The only way to regain control is to haul the stick all the way back
and hope everything holds together.

I have already played with the main wing center of lift, balance, horizontal
stablizer, and the MOI for pitch. I am at a loss for how to solve this
problem. Any suggestions?
