I have noticed the Mugen batteries that are designed for Futuba and Airtronics on MTX-3, also the batteries on Speedtechrc only.
However I own a JR-R1 SPCM receiver and am worried that there are no batteries that will fit.
Will any of these two batteries fit on the JR-R1? Or am I left with the following options:

1). Buy a Futuba receiver or Airtronics and use it with my JR-R1 radio (if it is possible?)
2). Buy a new Futuba or Aitronics radio kit?
3). Make my own battery with the a JR-R1 connector ( last resort as I am not good with electronics)

Thanks for your help

The Airtronics one should fit with the JR receiver, just make sure that the black is where the brown(I believe) should be and the red where the red should be in the rx.
