With regards to the spectator aircraft, the paper plane, I've made a change to the aircraft.cfg so that the contacts point line up, and the aircraft sits straight and level, instead of leaning to one side. This'll be better for watching the display from the virtual cockpit.

Simply replace the [contact_points] section with:

[contact_points]
point.0 = 1,  0.90,  0.00, -4.09, 1500, 0, 0.5, 22.0, 0.25,2.5, 0.7, 0.0, 0.0, 0
point.1 = 1, -4.70, -4.50, -4.01, 3500, 1, 0.5,  0.0, 0.3, 2.5, 0.7, 0.0, 0.0, 2
point.2 = 1, -4.70,  4.50, -4.01, 3500, 2, 0.5,  0.0, 0.3, 2.5, 0.7, 0.0, 0.0, 3
point.3 = 2, -3.90, -18.0,  3.00, 1800, 0, 0.0,  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 5
point.4 = 2, -3.90   18.0,  3.00, 1800, 0, 0.0,  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 6
point.5=  2,-20.23,   0.0,  0.30, 1800, 0, 0.0,  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 9
point.6=  2,  1.48,   0.0, -2.17, 1800, 0, 0.0,  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 4
point.7=  2,-22.80,   0.0,  5.83, 1800, 0, 0.0,  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 7
point.8=  2, -4.90,   0.0, -2.00, 1800, 0, 0.0,  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 8

max_number_of_points = 21

static_pitch=3.02
static_cg_height=3.765

Hope this helps!
