Hey Guys, I've got this JR Sport S400 radio that I want to use for my Alpha 40 flight simulator and I'm not sure what size battery to use in it. The radio that came with plane isn't what I want to use since my simulator is on the work computer but I need to practice more landings. I didn't want to haul the original radio all over the place so that's why I got the JR Sport. I thought all JR radios would take the same size battery but guess not.

The standard rechargable NiCd pack for this radio is 9.6V 600Mah. You'll want to make sure you're getting a JR power connector on the batter when you order one, I believe the polarity is reversed compared to Futaba, Airtronics, or Hitec.

Thanks Biged!
