JR Max 4 Tx manual and charge question
Anyone know where I can get a manual for a JR Max 4 Transmitter? Does anyone know if a futaba wall wart charger will work with the JR?

RE: JR Max 4 Tx manual and charge question
I am not familiar with that Tx, but JR has traditionally required their Tx charge jacks to be Opposite in Polarity from the Futaba charge jacks. The Futaba Wall Wart charger should not work with the JR Tx.
If you took the battery out of the JR Tx and rigged up a connector, for the Futaba Wall Wort charger, so you could plug in to the JR Tx battery, with the correct Polarity, it would work, but you can probably pick up the correct Wall Wort charger for next to nothing. I see them all the time at trade shows.

is your radio the JR MAX 44 ? if so i do have the original manual for this radio and can post it to you if you pay the postage. also the charger will work fine as long as you make sure the tx polarity is correct with the charger plug.

Wall Wort chargers are OK, but you are better off in the long run to buy a charger that can Cycle the batteries and give you a more accurate idea of how well your batteries are holding a charge. This applies not just to the Tx batteries, but your Rx batteries, as well.

RE: JR Max 4 Tx manual and charge question
The futaba charger will not work (as is) with the max 4 JR since the polarity of the plug going into the charger is reversed. It could be modified (cut the wires/swap the wires) but if you are new to electronics I wouldn't advise it...a wall charger made for the radio is the way to go...find someone close to you that flys JR. If you were close to me I would give you one since I have a drawrer full of em.
