Another factor to consider is the cost of subsequent receivers as your fleet grows. Fasst and Specktrum receivers cost a fortune for what they are (IMO), which is why I like the idea of being able to use the cheaper S-FHSS 2.4gig system that the 14 ch futuba radio I list above offers (on top of it's ability to also use the other two 2.4 FASSTest and FASST receiver options ex Futuba should you want more confidence on expensive planes).
Hitec look to be charging a very reasonable amount for their receivers, which for me is a good thing.

The thing I am getting at is that once you have got a transmitter, it yours and that's that, you don't need to buy a new one for every new plane - receivers are another matter, and are thus should be a future costing factor to be considered IMO.

Now I use a Specktrum DSMX system, and it's great, I can't complain about it at all - it's been great full stop - reliable, easy to use, secure, easy to get accessories parts etc (excluding the branded receiver pricing, that is never been cheap). I can use 2s LiPo's directly with the right high voltage servos, and it's NEVER failed me, and I'm stoked that I have the telemetry option for my more expensive models.

Would I go that again knowing what I do now? (and the fact most round me DON'T use Specktrum), it's hard to say, but if I'm honest, I odds on would not on that basis (I'd personally go Futuba 14ch re my local external preferences, and the ease it would have made the learning curve for me PERSONALLY).

After all that, weight up your specific situation, go into it without any brand preferences (excluding what the majority of people around you use, that should be a consideration), and look at what your money gets you THEN get the best system you can afford. A Specktrum DX8 or 9, a Hitec 9ch and or a Futuba 14ch system will see you right for many a year to come in my opinion, regardless of what one you go for.
