Amphibians Jumping into air when taxiing from water to land

Hi all,

Just wanted to know if anybody knows which line of aircraft.cfg must be tweaked to avoid that annoying effect of airplane being shot into the air when passing from water to land.

I am quite sure must be some configuration to be changed, because i.e. I am Flying the Redux Goose and was working perfectly, then I applied the Real Dynamic and started to jump and sometimes even flipping nose down till CRASH. But if I keep using the HP version of the plane where no Dynamic changes were applied, it's still working fine.

Other example is Aerosoft Twin Otter Extended, as soon as touches land, no matter the inclination, it bursts in air in a 180° flip ending in a crash.

Any suggestion would be more than welcome!

thanks
