Great mod, it's the best way to get around the map if you have a lot of land area to cover.
My only minor complaint is the heli will pick up damage from bug spit on the ground if you fly over it,
the same as if your avatar walks over it on the ground. I can understand if a worm has a lucky shot and hits
the heli in mid air but spit on the ground should not transfer to it in flight. That would be my wish list for a fix but
it's still one of my fav mods for the game.

thats because the helicopter looks like hes flying but its still a land bound vehicle, when in flight mode there is no collision detection. the old mod/dev has answered this question a few months even a year back. no offence.
