    It's the BEC (generic 7805 LDO regulator) that gets silly hot on the 10A's when running higher then 3S, if you unsolder it and use an external BEC/RX pack they can go closer to 18v (Naked Turtle ran...

    Don't use a servo to trigger the microswitch, if the servo fails or jams, you cannot turn your weapon off (VERY DANGEROUS).

    What's the size restriction for motors to fit into the robot and what RPM range do they need to be in?

    I don't turn the wheels down, but I do drive the robots on rough concrete to wear that initial few layers off, which also allows the wheels to wear to suit the robots particular stance. The...

    I love the wheels, but I just do not have the weight to utilise the available potential. Annoying Box Rush's fight against Plastic Fantastic showed it evidently as PF's drill motors with two 100x20mm...

    The F20A was the 25A ESC that BotBitz use to sell before it was replaced by the 30A ESC's.

    Since Max/Maxine need to be asleep/unconscious for the transformation to happen, I'd expect them to be a bit off game when they come to, so that's a fair handicap :)

    I found wide wheels to be an issue with my Dewalts. Running 4"x2" colsons have too much surface area for the weight of robot and just allowed excessive wheel spin. I'm currently looking at stepping...
