    Here's a question I haven't heard since I first started playing airsoft a couple of years ago:

    Which is better?
    a. Gun on semi-auto
    b. Gun on full-auto mode but doing single bursts to fire 1 bb at a time

    I know semi puts more stress on the motor, but which one of these scenarios is better for gun longevity and battery life during a game?

    Neither. Either way for each shot you are starting the motor from a stalled state,which is when it draws the highest current. At least with firing in semi auto the piston will come to rest in about the same place every time.

    Unless you have a mosfet that always completes the cycle you'll use slightly less power per shot in full auto. This is because the motor won't have to do a full cycle every time and less inertia from the previous cycle is wasted.

    If you're going to fire a few shots in full auto then you will use less energy per shot as you're not having to accelerate the rotating mass from a standstill each time.

    Kinda odd silly question.....

    if you was really being picky then technically AUTO & single shot
    ONLY coz you won't be using/wearing cut off lever/trolley as it doesn't pop off the trigger sear

    I'll use SEMI for ergh SEMI & AUTO/short semi burst for ergh AUTO/larger bursts/spray n pray
    (coz I can't hit a barn door or that cheating mofo ain't calling his hits)

    Semi is worse than full auto because you're repeatedly starting and stopping the flow of current. Firing single shots in full auto does the exact same thing.

    You guys seem to forget that in a regular AEG the piston will stop in random positions with a random degree of pre-cocking, but more pre-cocking than with semi-auto. This will make the average single cycle in full auto slightly shorter than in semi auto, thus it'll consume slightly less power for each cycle on average.

    Shooting single shots in full auto setting is a trick we used in "the old days", when we used low capacity ni-cd batteries. We did this to get more shots out of a full charge than shooting single shots in in semi-auto.

    shooting single shots on auto is easier the slower your gun cycles

    slower guns on semi suffer the trigger "dead zone" where the player released trigger too soon on semi and the COL is still raised slightly. New players force the trigger and learn the hard way that wasn't the wisest thing to do.

    If your gun shoots about 10 to 15rps then the dead zone could be a common issue
    If your gun shoots about 20 to 25rps then you should have no problem bar a small overspin
    If your gun shoots about 30+rps then you might get double firing
    (depends on spring and your homework you did upgrading bits etc....)

    BUT on AUTO and staying on auto you won't get the trigger dead zone or wear your COL
    Still think it is a daft question tbh so I'm not bothering to vote
    I'll use semi for semi etc.... like I said earlier

    You'll of course shoot single shots more reliably in semi auto, but the question was what uses less energy per shot. Semi-auto cut-off jams are caused by a poorly shaped trigger trolley and/or cut-off lever. If both are shaped correctly the cut-off lever will simply be moved out of the way by the trigger trolley.
