I am the inventor and vendor of the Wireless Buddy Box by 2icrc - let me clarify and expend on the topic.

As far as my product, the trainer cable on the ground is eliminated by virtue of having two receivers onboard. These two RXs have two independent TXs on the ground, hence, no cable between them. So, in actuality I am not using any technology that would introduce what you are mentioning. Furthermore, there is no latency time on switching control to the secondary pilot and back. Futaba is coming out with a Wireless Buddy Box for their FASST Transmitters, it is a receiver that attaches to the trainer jack. The secondary TX communicates to the RX dangling on the back of the master TX, then finally out the antenna of the same. Futaba people saw my presentation at XFC 2009 in Muncie. They had their version of the Wireless Buddy Box at their table next to mine....their rep told me late 2009 due date at $100 dollars. (I should have taken a pic to attach to this post, I asked him for literature but he told me he didn't have it yet...) So in Futaba's case, the trainee inputs go through two stages in "talking" to the RX dangling behind the master TX then the master TX sending the inputs to the aircraft....so, doubledee here is your loss of punctuation/latency.

Futaba will approach all of your questions and doubts all the same and justify why you should buy their product. All of their rational will apply to my product, however, for the additional $40 bucks you get features they simply don't have and cannot touch. Fact is, none of these big companies are in the market of creating products that enable us (modelers) to go and buy other people's stuff. (We all know that.) Futaba wants you to keep buying Futaba and JR wants you to keep buying JR and so on. Futaba's version of the Wireless Buddy Box is truly simply chopping off the wire at some money cost without giving you any extra features whatsoever. Did I mention only Futaba FASST to FASST TX will be able to use their Wireless Buddy Box...

A product like mine, that enables you to use products spanning time from AM radios to 2.4Ghz and across brandname lines together is simply not in Futaba's/JR's/Spektrum's (and so on) interest.

Futaba has realized the marketability of giving their consumers the freedom of not being connected to one another - so they put money and engineering effort into creating their version of their Wireless Buddy Box. Well, I too saw that prospect, but put out something (sooner) that offers features and applications well beyond cutting a trainer cord (unlike, Futaba).

So time will tell, Futaba is going to make their move....the reality is that my system is much greater then a Wireless Buddy Box. Rather, it is a Co-Piloting System useful for Co-op Training, Co-op Piloting, Co-op Competitions and Redundancy. But I had to start somewhere, so for now, my product is dubbed XPO Wireless Buddy Box - it was the clear marketing choice for me to begin with....

....but I am realizing that what I have is much bigger than what the terminology "Buddy Box" evokes and is traditionally thought as....

I will be at the Big Apple Jet Rally, NY and Warbirds over DE....other events too, soon to be posted on my website. If you are in the area, come to these shows and see my product demo before your very eyes, seeing is believing.

(Anybody else go to XFC 2009 and see the Futaba Wireless Buddy Box on their table?...between the Futaba TX's and O.S. engines....)
