It doesn't solve it.
Even at very slow speeds, the server would crash most of the time.
I have seen/experienced it.
Stratofortress's vehicles never crash my server. even when starfishs ram them. they explode instantly on impact. my server has been up for like 20 hours straight without a crash.
and on his server even his helicopter didn't crash anyone or the server on someone ramming it. and it uses pretty much the same functionality as gravity's helicopters, with the added twist of the rotors starting up when the player enters.
It's worth a try at least.
