Sorry guys, the Futaba system is NOT Nomadio technology as some would like you to think. Futaba developed their own system for 2.4 same as Sanwa and the forthcoming KO systems.
The 4PK will switch for lefties. It's very light even with the stock battery installed. Looks a little funky but you get used to it. It also comes with the Hara trigger for those of you who have smaller fingers or like a tighter feel for push braking.
