Maybe spot weld those cleats to the top of the chain links?
And the bigger bot---do I see one (or more) of those cheap Walmart wireless camera's (one of those that transmit direct to channel 3) on your shopping list? I've got one of those...works pretty good with crappy antenna's out to about 200ft with a bit of overvoltage at the TX (11.1v vs 9v, 12v w/3 diodes in series).
