In the hanger when you choose your gun package, stop picking the RB one, RB- dont stand for real bullets, it means rubber bullets. gezzzz mon! In ww2 they made some planes outa rubber, so if you try to kill a RP-rubber plane, with RB-rubber bullets the result is obivious, bouncey -bounce. hehe!
Ive shot down some of these RP's and seen them bounce on the ground only to have them go to tower and I get No kill and they get a ditch! oh and there Is rubber trees too! bounced tanks off of them SOB's
