First time building a flipper robot

It's because you drive single stick not two stick like a pro Gareth

A quick question regarding the radio gear. I was looking at the Spektrum DX5e set on the Robochallenge site, and I wonder if that's a good one to go for?
I know next to nothing about RC equipment, but I figure I need a system with one channel on a switch (which I would use for the flipper) and this seemed like the most basic one with that feature.

Spektrum DX5e with a proper receiver (which Robochallenge will undoubtedly have) is a good setup for robots, including flippers. It is nothing fancy but then you don't really need fancy in combat robotics.
