No post anterior, se foi interferência eu não sei, mas leiam um trecho de um artigo escrito por um engenheiro eletrônico bem experiente. A parte que interessa para nossa contínua briga está em vermelho.
Quem tiver interesse em ler o artigo detalhado ou outras coisas interessantes, o site deste vovô é bem legal:

COMPARING 2.4GHz SPREAD SPECTRUM RC SETS
So which is best?
As I said before, there's no absolute "best" 2.4GHz system because everyone's priorities are different.
If you want a system that offers a wide-range of different receiver sizes and capabilities with maximum diversity on very large models then the JR/Spektrum offering has much to offer.
However, if you're looking for a "technically superior" system, it's hard to go past Futaba's FASST. Unfortunately, at this time there are not a lot of receiver options and Futaba has been very slow on delivery of some options.
If you're prepared to be an early-adopter then the new wave of low-cost offerings out of China may be worth a try. Check their specifications carefully though, and also keep an eye on the various discussion forums around the web. As first generation products they may have some as-yet undiscovered problems or limitations.
About the only system presently on the market that I would be hesitant to recommend is XPS.
As I said earlier, many people have had no problems with this system and it has worked perfectly for them. However, from a technical perspective, too many of the system's wild claims are unable to be substantiated by the manufacturer and the growing number of dissatisfied customers must be a concern worthy of consideration.
