    Ok so I'm looking to upgrade my M4 and so far I have a 6.03 TBB and deans installed. And I'm wondering what else to upgrade. Also if I went to lipos would I have to get new gears or anything, because I remember someone saying that King Arms M4 Ultra Grades already have SHS gears in them?

    Lol. What in the world are you talking about >.<

    You can run a 7.4v LiPo battery. No problem.

    An 11.1v LiPo in a stock internal king arms will destroy itself in no time (some time lol).

    Nope. None that I can think of. Been running 7.4v's for years and no problems.

    I'm thinking speed, like maybe about 25 RPS.

    I would suggest correcting AOE to help reduce stress to the front of the gearbox and the piston.

    You can use stock gears if you want. Shim. You can use the stock motor with a 11.1v LiPo and hit 25 bps. (11.1v 20c 1500 mAh and under) 30 amp output and lower is a safe number.

    Grab a cheap #14 o-ring and replace the stock piston head o-ring

    For longevity, correct AOE and install a FET unit.

    If done correctly, your gun can last a long time without having to install aftermarket pistons, motors, and etc.

    If done incorrectly, your gears will strip or piston will strip.

    I have over 3 King Arms M4's out running on mostly stock parts. Mild upgrades. Tried to be the cheapest cheapest durable'ish builds lol
