OK, I think I have a solution. It *does* have to something to do with the
new gear features. Also, there was a problem in the aircraft specification
file for the TAIL landing gear:
<max_steer unit="DEG"> -10.00 </max_steer>
This should not be negative. I don't know if this had any effect, but I
changed it to:
<max_steer unit="DEG"> 10.00 </max_steer>
Also, for *each* landing gear BOGEY, I added this line near the bottom of
the spec for the left, right, and tail bogey's:
<relaxation_velocity>
<rolling unit="FT/SEC"> 0 </rolling>
<side unit="FT/SEC"> 0 </side>
</relaxation_velocity>
This turns off the fade-in/out for forces at near-zero or zero velocity.
Turning it off is probably too harsh, but it should result in getting the
aircraft flying again. I can tweak the relaxation velocity to reduce jitter
and to allow the aircraft to fly normally. I'll try that later. Feel free to
play with that.
Here's the engine definition I'm using:
<piston_engine name="ASH-62IR">
<minmp unit="INHG"> 6.0 </minmp>
<maxmp unit="INHG"> 41.4 </maxmp>
<displacement unit="IN3"> 1823.00 </displacement>
<maxhp> 1000.00 </maxhp>
<cycles> 2.0 </cycles>
<idlerpm> 400.0 </idlerpm>
<maxthrottle> 1.0 </maxthrottle>
<minthrottle> 0.2 </minthrottle>
</piston_engine>
Yes, I agree that our engine specification and some features are not
optimal. For right now, I hope this helps until we can look at that problem.
Let me know how you this works for you guys.
