RE: Airtronics Vanguard question
I have an older Vangaurd 4 Ch Tx and a new VG400 & VG6oo. The newer battery packs will fit the older Vangaurd, and using that Tx I can even recycle all my Tx battery packs with my Hanger 9 Sure Cycle. This is a rather inexpensive Battery cycler and well worth it rather than just a regular wall charger. FWIW
