    Crappy batteries do exist even from new, but old used batteries seems the likely cause.

    Help with DIY Polarstar FCU Harness

    Perhaps the connector types are incompatible. I had a quick look and there's no wires crossed over so gotta be the connectors looking similar but actually not Perhaps you can check the continuity

    What brand gives you bigger bbs..5.98

    I'll ask my place to weigh some bbs too. Never thought of doing it before

    The problem with cheap scales is the sensitivity, lab scales should do the job tho

    How do they do that?

    Yeah a thin rigid plastic or metal body will transmit that sound quite well and with your ear next to it will seem loud. Butyl will reduce this alot, esp to anyone distant. The barrel report which is directional potentially can be heard at greater distances if it is loud, but as we know some...

    What does the original look like  Did you make the cable yourself?

    How do they do that?

    Whilst I've not gone into this too much, there's air pressure making a soundwave and the sound from the slap of the piston travelling out the barrel that can be dealt with by a silencer. Baffles help with noise and foam will absorb some of that sound. Baffles bend the sound away from the BB...

    How do they do that?

    Ppl will get the gearbox as quiet as they can. Gears whirr and don't always mesh properly regardless of shimming  but it's a worthy task. Reduce the piston noise with pads or even an airbrake, match the spring and volume to reduce the slap and the muzzle report. Pad the reciever with butyl...

    Are you increasing the lipo voltage and if you are adding a MOSFET will you use precocking?

    Vorsk EU18 Issues with hammer disconnector, slide not reutnring to normal position after firing/being pulled back

    Your first pic shows the metal sticky up bit (msub) alongside the slide when it should be under it. Either the metal parts holding the msub have moved, the slide is not on right, or really loose. I cant see the msub bending unless the metal parts at the rear have moved, it looks good from here...

    Vorsk EU18 Issues with hammer disconnector, slide not reutnring to normal position after firing/being pulled back

    It doesn't sound like you've done more than field strip it for cleaning. I'd go with some error when assembling it again.

    What brand gives you bigger bbs..5.98

    yeah, micrometer for the win. calipers can be influenced. Ive accumulated 3 or 4 sets of calipers, from an old vernier one, to a plastic £5 set, which works well enough but cant be trusted.

    Brushless upgrades

    As Leo says a brushless motor is like any other, but it will run cooler, spin up faster, can have more torque and because it has 4 magnets and 3 poles(6 effectively because they operate in pairs) runs smoother. You don't need one but it's just a better way of getting the amps to spin a motor.

    battery science

    Nimh get warm when they are full and are kept charging. They rely on the detection of a small drop in voltage at full charge to stop charging and if that is not detected correctly the temp will rise, basically because no more charging can be done and the continued current heats the cells. If no...

    AK2M4 / XT Brushless Motors

    The current that flows is regulated by the resistance of the circuit so any reduction in resistance increases the current flowing. It's motor load that raises the current predominantly because as you can see from motor stats, with no load you're seeing around 2A. Increase load and you raise the...

    The most economical source of gas

    Refilling from a larger propane tank is the most economical, but you do need a little kit to do it. Getting Airsoft gas in bulk will save money ofcourse and allow you to use a higher pressure gas if you desire. Most bottles are 300g, ASG are 270g net, Nuprol 300g for example.
