    I think they were 10k, but it doesn't matter hugely as long as they're decently high. It's just a doubled-up version of the board in this: https://www.arduino.cc/en/Tutorial/Button

    Sure, sorry it's a bit cryptic but it's really nothing too complicated. All that little home-made board is for, is to attach two push-to-break switches to the arduino (blue board). The resistors just...

    Advantage of TX mixing: No need to buy a mixer. Just get a good TX and it will pretty much last you forever, on all your robots.

    Also consider these. They're longer so you'll have more support for your wheel on radial loads. Also if you're melting them into a hub, I like to take a grinder with a slitting disk and just cut some...

    Personally I'd go with the first one, because a) it's harder to get high reduction out of pulleys (the gearbox will likely be much higher and won't slip) and b) I like Sewer Snake, and that's how...

    All looks great to me. If it were my bot, the only thing I'd be worried about would be horizontals riding up those side skirts and clipping the wheels, but there aren't a whole lot about in FW at the...

    Looks good to me. KV is about 300 higher than Aegis' motor, and power is more than double, so maybe half-expect to strip a gear or something? Just be very careful if you test it before you've added...
