i love my 403, but my only gripe is with the batteries that came ith it. i got it over a year ago, and it came with 600mah batts. i couldn't stand them because they died very fast so built my own pack using 1700mah nimm. this should be standard. i am also eagerly awaiting a 2 chanel fm receiver or a 2 channel switching receiver and module. i also love it.
