RE: Cycling And Recharging Problem...
If that is the female end of the plug, then yes that will work. You could also make your own adapter if you'd like. Its very simple.
As far as cycling the tx battery....my futaba has the diode as well. So I would have to pull out the battery to cycle. Considering I only cycle the battery twice a year, its not that big of a deal.
I have the same charger. I love it! Its been great to my nimh tx/rx packs.
