18MZ battery charging
The charger that came with my 18MZ appears to be a 12 volt power supply with a 2.5 amp output. I assume that the charging circuit resides in the Tx or battery itself. If in the unlikely event I should need to charge the Tx battery at the field can I just apply 12 volts to the charge jack utilizing the correct plug on the back of the Tx and therefore charge the battery? Thank you.

RE: 18MZ battery charging
I am thinking of doing this for the just in case situations. The outside of the coaxial plug is 5mm and measures 12 volts DC. I found the plug here but have not tried it. [link]http://www.thefind.com/search?query=dc+coax+plug+center+pin[/link]
I plan to connect this to a standard cigarette lighter plug with a 2 amp fuse. I would only charge the transmitter with the engine off to make sure there isn't any ripple going to the transmitter.

OK, we found out: Futaba says that the transmitter can accept up to 20V DC as input. The actual charging circuitry is inside the transmitter. You can use a 12V DC power source, such as a power supply connected to an AC outlet, or an automobile battery.
