Air File Assist Please

I adjusted the contact points to allow for prop strikes on the Beech. Now, how can I get the rear end to stop sinking so low after making a wheels up landing?

Also, how do I move the center of gravity forward in an aircraft CFG file (not for the Beech)?

Thanks

Now, how can I get the rear end to stop sinking so low after making a wheels up landing?

The Beech's contact points are as follows:-

[contact_points]
max_number_of_points = 10

//point.0 = 1, -19.904,  0.000, -0.637, 2200, 0, 0.33, 45, 0.51,  2.0, 0.50, 3, 5, 0, 139, 175.2
//Replace contact_point.0 below with the one above if you want a steerable tailwheel.  You may comment out the one below with //, and activate the one above by removing the //

point.0 = 1, -19.904,  0.000, -0.637, 2200, 0, 0.33, 180, 0.51,  2.0, 0.50, 3, 5, 0, 139, 175.2
point.1 = 1,   2.890, -6.417, -5.987, 2200, 1, 0.8,    0, 1.15,  1.1, 0.50, 5, 5, 2, 139, 175.2
point.2 = 1,   2.890,  6.417, -5.987, 2200, 2, 0.8,    0, 1.15,  1.1, 0.50, 5, 5, 3, 139, 175.2
point.3 = 2,  8,     0,     -3,     1000, 0, 0,      0, 0,       0,    0, 0, 0, 4
point.4 = 2,   -1,     0,     -1.4,   3000, 0, 0,      0, 0,       0,    0, 0, 0, 4
point.5 = 2,    0,-23.495,     0.42,  1200, 0, 0,      0, 0,       0,    0, 0, 0, 5
point.6 = 2,    0, 23.495,     0.42,  1200, 0, 0,      0, 0,       0,    0, 0, 0, 6
point.7 = 2, -21.904,  0,      3,     1200, 0, 0,      0, 0,       0,    0, 0, 0, 9
point.8 = 2, -16.6,    0,      6.4,   1200, 0, 0,      0, 0,       0,    0, 0, 0, 9
point.9 = 2,   8.2,    0,      1,     1200, 0, 0,      0, 0,       0,    0, 0, 0, 4

The rear scrape points (.7 and .8) are apparently for the fuselage end and the height of the fins, so I'd suggest adding another scrape point very close to the rear wheel (point.0).

Increase max_number_of_points to 11 and add the following line to the list:-

point.10 = 2, -19.904,  0.000, -0.2, 1200, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0

The height can be adjusted by editing the fourth number in that line (-0.2) if need be.

Also, how do I move the center of gravity forward in an aircraft CFG file (not for the Beech)?

The CoG is governed by several things and they're all in the [WEIGHTS AND BALANCE] section. If you want to alter the position with reference to the model, but not modify the flight behaviour, alter reference_datum_position: the first number will move it forward or back from the model centre. If you fancy messing with the actual flight behaviour, the three CG figures should drive you crazy in a matter of moments. As a matter of interest, many of the stock models have the model centre at the spinner tip, rather than the actual CoG. Weird!

[WEIGHT_AND_BALANCE]
max_gross_weight = 8750
empty_weight = 5527
reference_datum_position = 0, 0, 0
empty_weight_CG_position  = 0, 0, 0
CG_forward_limit = .21
CG_aft_limit = .33

Have fun! :mixedsmi:

That did the trick!

Everything is sorted out now!:mixedsmi:

Thank you so much Hairyspin!:salute:
