All MX350, MX650, and MX850's manufactured after 11/06
have the narrow band transmitting antenna. Open the battery
cover and look at the series of numbers under the model
number. The last 4 numbers in the first sequence indicate
the manufacture date eg.xxxxxx1106, then comes the individual
serial #.
I stand corrected....In fact, Hank Eisengrin stated that exactly at his cedia class.
Some old URC literature ended up in my backpack and it reads the opposite, sorry.
