Jaximus Decimus Posted May 18, 2013 Posted May 18, 2013 I haven't got out my stopwatch and checked or anything, but the spool-up time on the M134's seems way too long. In my experience it only takes a couple tenths of a second to get wound up and start firing, but in the Huey it feels like it's at least half a second or more. I can look out the window and watch the barrels just spinning. I don't know if this was a characteristic of the older M134's, but current models definitely don't behave that way. At first I just thought there was a delay before my fire command would go into effect, like I had to hold it so long before the guns would get the command to fire, like a safety. But I can look out the window and clearly see the guns spool-up the moment I press the switch. That half second feels like an eternity when you've got your pipper locked on a moving vehicle and you need to get rounds out.
HuggyBear Posted May 18, 2013 Posted May 18, 2013 Yep, this has been submitted as a bug, no word yet as to if/when it will be fixed. There shouldn't be any noticeable delay between button and firing.

Jaximus Decimus Posted May 18, 2013 Author Posted May 18, 2013 Ok, I'm not the only one. Thanks, Bear.
Sundowner.pl Posted May 18, 2013 Posted May 18, 2013 (edited) There should be a bit of delay before the gun starts spinning, but barely noticeable (0.3 sec.) + first half of turn should be "dry", because the feeder/delinker is feeding rounds when a barrel and its chamber is in lower position (6-o'clock), while the firing position is up (12-o'clock) since the gun is spooling up to 2000rpm at this time, the delay here is around 0.05 sec. So from pressing the fire button, to first shoot should take roughly 0.35 sec. The guns should stop firing after 3 seconds because of automatic system disabling the feeder/delinker, and gun is spun without any ammo for 0.3 second (10 full revolutions) before stopping. Note that in Vietnam the miniguns were fired for minimum 2 seconds, because of jams resulting by continuous "bullwhipping" the ammo belts if shot in very short bursts.

Jaximus Decimus Posted May 18, 2013 Author Posted May 18, 2013 Nice find, Sundowner. Where's that info from?

Flagrum Posted September 4, 2013 Posted September 4, 2013 The spool up time is now with 1.2.6 again very long - way over 0.5 seconds. :(
Flagrum Posted January 21, 2014 Posted January 21, 2014 The spool up time is now with 1.2.6 again very long - way over 0.5 seconds. :( 1.2.7u2 change log: UH-1H. Spinup time decreased. This seems to apply to this bug. Re-tested: yes, it's fixed!! Yay! Thanks! :thumbup:
