ok good point about the sidewind, maybe i can loose some material on the sides, doesnt need to be full i think.
i put it a bit lower so i can access the deck once the rudder is removed. dont have to unscrew the whole thing.
probably ill be using 6inch propeller but 5 might do too.
the rudder is the biggest probelm, theoretically it should work like on an real airboat, but if it dosnt work out i can still
use a "normal" rudder ;)
