I've had a bit of a play around with ideas in my head, and I reckon a strong rambot or wedge is probably a good place to start. Are these basic parts suitable for a beetleweight? I've done a bit of reading and think I've got things right. Correct me if I haven't!

Motors (x2? or is 4 wheels reasonable for beetleweight?): https://hobbyking.com/en_us/turnigy-...ner-motor.html
Speed controller (same number as motors?): https://hobbyking.com/en_us/turnigy-...-bec-besc.html

For armour and wedges and so on I've read that cutting boards can be a cheap source of strong plastics to start with, what thickness am I looking for, and how much should it weigh?
