Radio for crawler ?

[rchippie]

Im considering getting a crawler & have a couple of ?'s about radios . Can i use my m8 or is a stick radio better ?. I would'nt be entering comps or anything . The crawler im looking at does'nt have dig. So i would'nt need extra channels as of yet . I dont want to have to get another radio in case i dont like crawling . My m8 has a auxillary channel . could i us that for the dig unit if i get one latter ?.
