After a few months in the pipeline, I've finally come up with a design, alongside a basic circuit diagram.

I'm trying for a low to the ground, compact, fast and maneuverable rammer. The design shows I'm going for a 4WD approach, and the circuit diagram shows a compact looking design. The only issue is how to create the 4WD system with only two motors, I can't decide between the heavier and possibly more fragile drive chain and sprocket approach, or the lighter and possibly more durable belt driven approach

With regards to event types, I'm unsure about going to Robochallenge unless I have a lot more experience (knowing fully well that robots like Mr Mangle, Drumroll 2, amongst other spinners could tear it apart) so at least for now the live tour events.

I've figured out what components I'm going for:

- 2 REEDY Wolfpack NiMH Battery Sticks (with Deans plugs)
- XT60 - Deans plug adapter, three way XT60 adapter for a Safety link mount, with a XT60 for a safety link
- Sabertooth Speed Controller/BotBitz 85a v2 Brushed ESC
- 2 Argos Value Drill Motors
- 20mm HDPE
- Ranglebox M6 Threaded Bar with M6 bolts
- Colson Performa wheels

A quick question on speed controllers, out of the Sabertooth and Botbitz 85a which one is recommended for a 4WD robot with two motors?
