Yeah, that's what I was waiting for, when they didn't shoot the thing right away. I was sure that with the first shot, the copter would just disappear -- as in, exit, stage right, at great velocity. Or something.
It also doesn't sound right -- sounds like caps. It might be shooting something, but that ain't no .45.
Also -- accident waiting to happen. Would you be standing anywhere in the vicinity of a remote-controlled trigger without bulletproof glass? Can you imagine if the first shot ended up aiming the gun at you, and then the trigger somehow accidentally got pulled a second time?
