Rectangular 8 cell Tx battery case with a 9V connector molded
in one end. It fits radios such as the 3PB (if you're not using NiCds).This will also work on the 2P, 2PKA.
If you are tired of replacing expensive hard to find 9.6v Futaba NiCd transmitter packs this is the answer. This holder allows the use of 1.5v AA size cells to power compatible Futaba or Hitec (with minor modification) transmitters.
