Ian Laing Posted December 11, 2009 Share Posted December 11, 2009 Can anyone help me with the exact dimensions of the jack plaug used to plug a charger into a Spektrum DX6i ? (any Spektrum Tx should use the same size plug) I want to use my Graupner ULTRAMAT to charge the Tx battery (4.8 volt, Eneloop cells). I went into Maplin to buy a jack plug to be confronted by different sizes! You get a 5mm or a 5.5 mm plug and the negative pin in the plug also varies in diameter! HELP!!

Jonathan Lewzey Posted December 12, 2009 Share Posted December 12, 2009 i bought a multi type lead from robotbirds which comes with a JR tx charge lead aswell as a futaba tx, universal rx, deans and JST. See here. Just make sure the charger is set to 4.8 before charging if it doesn't automatically recognise the number of cells and determine which is the futaba and which is the JR plug. They are very similar, but are reverse polarity. One doesn't fit on the other so you should be able to find which is which and label them as i've done.
