I am a newbie and I am interested in scratch building the Mini dart. I have most of the the required items except for motor mount pods and power distribution module. I do not plan on running any extras ( i.e cameras, lights etc... )do I need the power distribution module? Do I have to have a a 6 ch receiver? Can I use a 4 ch receiver and pair it prior to plugging in the 2 motors and 2 servos?
