Radio setup in QGC without 4+ channel radio

Hi Guys

I am new to the autopilot environment and would appreciate some help.

I am trying to put together a autonomous rover making use of gps positioning.

My issue comes in at the setup of QGC it seems that i require a 5channel radio to complete the radio setup. is there a way around this or by making use of an app based program to complete the setup?

Thanks in advance
