playerdata can flight ?

Hello,


I try to make a RTS game (as in the tutorial)but with airplane.
the problem is there are no movetodestination,movetonode,nextnode,... with flyingvehicledata.
and if I use playerdata he is on the ground
are there some parameter to make a playerdata flight in the air ?
or another object to make this with a set movetodestination

thanks
Dany
