  1. How the link didn't work? Did you get the login window where you should type the words which are told in the window?


    Kanzen 8mm ceramic ones were too high. Gears didn't fit and they were also too high on the other side and touching the selector plate.


    Can you tell what kind of stories you have heard? I must admit that I have managed to break one set of gears. But I think it was due poor lubing....


    Oh wow, somehow I didn't get notified when you posted your reply. Sorry about that!


    I just had another go at logging into the registry and it worked fine. I must have had caps lock on or something last time. :rolleyes:


    Thanks for letting me know about the Kanzens. They were going to be the next bearings I tried. I can't remember anything specific about those Modify gears, but I know they're prone to failure. When it comes to gears, SHS are just as reliable as other gearsets bar Siegetek. So either buy SHS or Siegetek, because anything in between is uneconomical.

  2. I didn't manage to get that link working :/


    Which specific Kanzen bearings didn't fit? Any were they too large for the bushing hole, or were they too thick for the gears?


    I haven't had a chance to try out those Modify gears, but I've heard some bad stories about them. I always use Siegetek gears since they're known to be extremely reliable.


    Please let me know what happens with your stock bushings. I might actually install mine, since I'm not happy with the noise coming from my gearbox!


    Those DC3 connectors look very similar to the XT60. I might actually be the exact same bullet connector in a different casing.

  3. Nice write-up.

    Do you have a full parts list of what you swapped out?




    Thanks Eric!


    I've replaced almost all the internal parts.


    • Extreme-Fire SW-AB-Long MOSFET custom made without AB (yeah, weird I know :P). I've replaced the fuse with one I made, and I've added a tracer unit control circuit of my own design, which enables any battery to be used with the internal tracer unit.
    • New wiring, using this 16 AWG stuff. It's nice and thin, but the insulation is tough and heat resistant.
    • XT-60 connectors - Loving them at the moment.
    • SHS High Speed motor - Excellent performance.
    • Modify 8mm ceramic bearings
    • Siegetek GS-R Revolution high speed gears. Siegetek gears are the best you can buy, and in my experience the only ones which can be considered reliable.
    • Guarder anti-reversal latch, but I'm currently trying to get the orginal one working properly.
    • SHS full metal tooth piston, lightened.
    • Trigger replaced with this micro switch, and installed this micro switch to activate the tracer. This took about two days of tuning to get right, but at some point I'd like to improve it with a more robust design.
    • Guarder SP120 spring - I haven't chrono'd it yet and I'll update when I do.
    • Air seal nozzle from AirsoftPro.cz
    • Sorbothane and urathane fitted to the stock cylinder head.
    • I'm going to experiment with a shorter inner barrel made by Madbull and appropriate cylinder that I have lying around, just to see how it affects the accuracy.
    • Guarder clear bucking, cut down to fit.
    • I have a few FlightTech LiPos that fit into the handguard, the largest is a FlightTech XS 2150 7.4V 50C (107.5A) measuring roughly 10.5cm x 1.7cm x 3.4cm
    • I always use a Wolfdragon PCB to protect my LiPos. I like the V4.x with trigger mod, which stops you firing the gun when the battery voltage drops below a safe level.

    Think that's it, let me know if there's anything I missed!

    I tried Kanzen bearings and they were too high. I wasn't able to shim at all and Siegeteks were too tight.to fit

    With original bushings/bearings I used only a few shims (some of my shims are 0.08 mm). That way I was able to fit those Siegeteks.


    Ah, that's very interesting! What's your setup? I'd be interested to know how well the original bushings survive in an upgraded gun, especially with Siegetek gears. I assume you're using the MAG stainless steel shims? They're my favourite ones, I'm waiting for a large quantity to arrive at the moment.:D
