I know people have converted a few of the 1/18 Bradleys to R/C. Ludwigs site has a Bradley listed, but no pictures or information on them.

There is another site that has the tracks and sprockets for a Bradley:

Those are the only Bradley related sites I can think of. A Bradley would be really cool though. Would go well with my Abrams...
