I was thinking of this for converting my two lads to 2.4
as they both have the 3VC TX's
Just went onto the FrSky website and downloaded the manual
and its basically plug n play like the Futaba 2.4 units
All you have to do is make sure the TX is in PPM mode which is in the
menus under MOD ( either PPM or PCM )

What units did you buy ?
