RE: spectrum pros and cons.
Its only seems slow to those that buy into the hype of one brand being so much faster than others, in use I would say its not much of a problem. Been a lot of races won using some type of Spektrum system. As much as I like the Spektrum systems I think if anyone can pony up the added bucks to buy the brown box Nomadio special then that would be the way to go, unless you already have a high end module based radio and can just install the Spektrum module and receiver.
