A few isolated instances of jumping have been reported, and this appears to be related to the damping ratios in the aircraft.cfg's [contact_points] being too 'real' (i.e. within too fine a tolerance) for some systems.
For those with the problem, please change the highlighted numbers to those as follows:
[contact_points]
point.0=1, -15.71, 0.0, -1.24, 1800, 0, 0.256, 60.0, 0.300, 2.5,
0.75, 0.0, 0.0, 0.0, 0.0, 0.0
point.1=1, 0.96, -2.95, -4.51, 1600, 1, 0.70, 0.0, 0.111, 3.27,
0.21, 0.0, 0.0, 2.0, 0.0, 0.0
point.2=1, 0.96, 2.95, -4.51, 1600, 2, 0.70, 0.0, 0.111, 3.27,
0.21, 0.0, 0.0, 3.0, 0.0, 0.0
point.3=2, -0.86, -17.7, 1.80, 800, 0, 0.000, 0.0, 0.000, 0.0, 0.000, 0.0, 0.0, 5.0, 0.0, 0.0
point.4=2, -0.86, 17.7, 1.80, 800, 0, 0.000, 0.0, 0.000, 0.0, 0.000, 0.0, 0.0, 6.0, 0.0, 0.0
point.5=2, -17.00, 0.0, 4.50, 800, 0, 0.000, 0.0, 0.000, 0.0, 0.000, 0.0, 0.0, 9.0, 0.0, 0.0
point.6=2, 5.40, 0.0, -2.20, 800, 0, 0.000, 0.0, 0.000, 0.0, 0.000, 0.0, 0.0, 4.0, 0.0, 0.0
For those who do
not have a problem with jumping, there is no need to change your aircraft.cfg.
New installers will be uploaded in the next few days, once we are sure this fix works for all instances of jumping.
Aside from this, thanks for all the nice comments!
