    Electric actuators use switches and diodes to limit travel, but that will...

    I can't find much information on these. I might be possible to change these ones, but not easy. Sorry for not being much help.

    You are using a brushed motor for the axe, so you can either use an ESC for a brushed motor or use an ESC for a brushless motor and change the firmware so you can use it in a brushed mode.

    That is one lovely looking bot :)
    I was wondering, you are driving two different diameter wheels. Is there a technical reason for this? (I am just curious)

    One thing I notice with your wiring (shown in link above) is that you have the black and red wire cut off one of your connectors. I worry about this shorting out and causing problems. It is quite...

    Yes, you can use the potentiometer if you have to. The potentiometer can be imagined as two resistors, which change value depending on how much you turn it.
    I think if you glue the potentiometer it...

    In reply to your post. That is what I meant.

    My thought with this, is that the servo is centered around a voltage that is not exactly half way between the rails. This test will check that you are...

    I am not sure how to use the transmitter. But you could change one of the resistor values slightly to get it a bit nearer center.

    Is the kill switch getting hot when you try to move it on the ground, or are you meaning it got hot when you soldered to it?
    Do you have a multimeter?

    I think if you connect on each switch:
    pin 1 (COM) to the motor
    pin 3 (NO) to batt+
    pin2 (NC) to batt-
