World Best Soldiers

I think you have got a mod mixed up with a hack. On the  our server most planes have auto-take off, meaning when you get in position 1 of the plane you get a boost.

For two piloted planes like the stuka if you switch from position 1 to position 2 then back to position 1 you get a boost.

For single piloted planes like the zero if you fly straight then get out of the plane and get back in quickly you get a boost.
