I've been doing a bit of fiddling .....
In the aircraft cfg to reduce the super sensitive pitch I altered the elevator effectiveness to 0.6000 ......
[flight_tuning]
elevator_effectiveness =0.6000 //1.00000
Added this to the [brakes] .....
differential_braking_scale=1.0
To make it easier to turn on the ground I altered the first line ....
[contact_points]
point.0= 1, -16.250, 0.000, -1.500, 1600, 0, 0.200, 45.000, 0.500, 3.360, 0.850, 0.000, 0.000, 0, 152.1, 179.9
In the panel cfg the Attitude Indicator was missing out of the 2D panel ....
gauge24=extra-300.attitude, 450,639,135,135
//gauge24=Pond_Racer_extra-300.attitude, 450,639,135,135
And the Throttle Quadrant didn't show with the icon so I changed the ident ....
[Window02]
Background_color=0,0,0
size_mm=512,384
window_size_ratio=1.000
position=0
visible=0
ident=THROTTLE_PANEL
//ident=30
window_size= 0.360, 0.730
window_pos= 0.010, 0.400
gauge00=Beech_Baron!Engine Controls Unit, 1,46,215,337
Hope this helps.
I love flying this racer

Pete.
