what radio do you guys like for a dual stick setup and how're you configging it? I'm looking at probably going for a Spektrum DX6i

(will be running 4WS, the R2 2-Speed transmission with dig, probably mounting the transmission backwards to get it to rear dig instead of front, as front wheel drive will be more beneficial when climbing than rear wheel only as I have a hunch front wheel drive with rear wheel locked or free spinning will help pull up the rock without flipping)

any ideas and suggestions would be greatly appreciated, thanks in advance!
