Guys, this is FS limitation. CS cannot do anything about this one.

It can be done two ways :

1. The way CS have done it. Rear wheels sink into ground slightly

2. Have the rear wheels NOT sink into the ground on takeoff. This will however create the effect of the aricraft being slightly off the ground when it is stationary or taxiing.

Different developers do it differently. You can play with it yourself by trying different settings in the "Contact Points" section of the aircraft.cfg. Look for point.1 and point.2 - (look for -11.70). Try increments and decrements of 0.5 and see which one you like.

But do not ask for support and make sure you keep a backup of the file before you start tinkering with it. ;)
