Is this ROF acceptable for an 11.1v lipo?

[lurkingknight]

that sounds normal.. it's a slow motor with a low output amperage lipo. That's just 30amps discharge total on the pack... 1.2A x 25C = 30amps. A reasonably set up gun will draw 15-18amps continuous. That's with ideal wiring, shimming and healthy motor and no mechanical binding.

the vfc scars will shoot slower than any other v2 by vfc even if they have exactly the same mechanical components. The way they are designed with the quick teardown like realsteel introduces a lot of resistance into the system. Nothing you can do about it unless you are willing to drill holes in the body to run continuous wire.

My friend's SSR has a slow rate of fire as well, but that's because it has a VFC black high speed motor and a M130 spring, which is what it came with stock. It's quite possible that there is nothing wrong with your gun.

Doing a quick search on other VFC scars using an 11.1v, they get a MUCH MUCH greater ROF

That's not THAT much faster. Figure out what kind of spring you are pulling first.

^^^^ this this this

Now on my Scar-L the stock motor (all black) is a high torque one which has an average ROF/Trigger response similar to the one in the OP's video. Now I don't know if it is true but I thought VFC changed which motors came in their guns since they first started producing them (I know that there are a Gen 1, 2, and 3 of the Scar-Ls and Hs).

Also could it just be the coldness outside? I mean even my Scar was struggling last time I shot it outside, but once I brought it inside it was fine.

Regardless avoid drilling holes in it if you can! It is not as easy as it sounds, I got someone to do it for me and after had I known how hard it would be to do, I probably wouldn't have gotten him to do it. It was borderline black magic, the kind even Voldemort says fuck no to.

LiPo's aren't affected by cold
And it could just be that you have a really shitty motor, or very high resistance in the electrical system.

The motor in my VFC Scar is silver, not black

I think I will get a gun doc to look over the whole gun. Its not a bad idea considering it is used and the previous owner upgraded it themselves

[bug519]

If you're going to get it looked at, might as well replace the trigger contacts..

I replaced mine with the shs, until I got the BTC spectre MOSFET which you should try to get when it's back in stock.


You may also want to look into replacing that motor, I know the red vfc motor is great, don't know much about the silver one.

It could also be bad shimming, or the wires in your pistol grip are where they shouldn't causing the motor to be misaligned .

[lurkingknight]

lipos are affected by cold... just not as drastically as nimhs.

vfcs have those ridiculous self shimming gears which are between too loose, too tight and just right depending on how you hold the gun. The only gear that's shimmed on both sides is the bevel gear.

Keep in mind this is airsoft... which means consistency even from the greatest manufacturers can be suspect. The motors they put in can be anything... whether it be different models, different production runs of the same model, different factories, different guy who wound the armature in the motor to how the magnets are aligned and balanced in the motor... the determining factor of what you get is more than likely based solely on price that the manufacturer bought that shipment of motors.

If you want to see how much resistance the vfc's scar wiring posts are adding, rig up a test rig and battery to the wire stubbs when you take the rear of the gun off to expose the shortened wiring harness at the rear of the gearbox and fire the gun. I guarantee you that you'll probably see at least 3-4 rps gain right away.
