it's said to be rather poor.

Limited range (max eff 200m) cumbersome reload, and for 1945 standards poor calibre did not make this a very useful weapon. Even if it would hit an aircraft (and this thing would have been difficult to aim), the damage of a 20/30mm would be probably insufficient. 
Why fire a fliegerfaust on a tank when you can use panzerfaust ? And after the war, no real attempts where made to copy this weapon, which also says something about about the impression it made

yes. it's quite nice. it has better armour then the tiger, lol.

Just finished my hummer



i got a new airbrush for Christmas so I used it as an "experiment"

Next project

It's an IR light

thx, i love free games

to be fare, tiger I is utter crap in this game. I hit a T34/57 in the side in RB at 10m range, nothing. He turns around, puts a 57mm round in my front armour, boom bye tiger. The german KV is just 10x a better heavy then the tiger. And why would you pick a tiger anyway if you can get a panther which has just a little higher BR.

Ostwind is great. I've killed more tanks with my ostwind then with my panther, true story.

wirbelwind is meh. Kugelblitz is an absolute rapefest. insane ROF, never has to be reloaded, it simply chews up aircraft, and it had a closed fighting compartment, meaning that aircraft are as good as defenceless.
