Default What do I really need in a transmitter?

So guys, I soon will want to buy a proper transmitter, since the only thing I have is a Spektrum DXe, which while it is good enough, I don't know of any ways of switching to other receivers A.K.A. different planes. Correct me if I am wrong about this please.

I saw that the Taranis QX7 looks very good, but people are sometimes bashing it for bad build quality compared to brands like Spektrum, Futaba and so on. However I do like the functionality of it with the transmitter modules, telemetry, how many channels? 16 or something? That's crazy! Where can one even use that many of them?

The only 2.4GHz receiver and transmitter I have right now came with the Apprentice S 15e (I think thats the model name) and so far, no trouble with it, other than the model switching I mentioned above.

But then I realized... What do I really need? My father has his old 40MHz 6ch Futaba and he only ever used 3 or maybe 4. It is true that he hasn't advanced due to certain problems, but why does one need a radio with something like 20 channels? Holy cow.

I read the FrSky protocol is very good, while the Futaba's FASST protocol is also pretty good, some are bashing Spektrum's protocol for being very bad and having brownouts...

Also, I fly mode 1. I learned with my father on it and I am not switching. If anyone has a problem with it then #DealWithIt

You have a Spektrum already? A higher level Spektrum would work with what you already have, and their reputation is a lot better now. I like my 6e a lot. My Taranis QX7 is way more difficult to program than the 6e.

For your average 4-5 channel airplane, you don't need more than probably 7 channels at the most, maybe 9 if you are flying a full house airplane with some additional functions. But for pilots like me or other fellow giant scale pilots, we run out of room quickly with 9 channels where we often have 2 servos per aileron, 2 on the rudder, and one for each elevator, not to mention things like an ignition kill and throttle servo- that's 10 channels right there, and bigger airplanes mandate more channels (I have one airplane that mandates 16 channels for all 15 servos onboard plus electronic ignition kill). Aside from that, scale aircraft often times have additional functions that eat up more channels with scale retract functions or things like scale canopy movements- you can see why a 20+ channel transmitter is appealing to certain pilots. Of course we can get away with using a 9 channel system and some kind of power expansion device that can handle a large number of servos, plus mixing options, but it's not appealing to most.

It's ultimately up to you what you decide to run though. A 9 channel system is a safe bet these days for a large number of airplanes and leaves headroom to progress into some bigger airplanes.

Default What do you need in an airplane

The question you need to ask is what do you need in an airplane? Are you sticking with mid-size sport aircraft? Are you thinking of giant scale? Or jets? What about Heli's? And quads? Figure that out first. If the answer is sticking with mid-size sport aircraft you have the radio you need. If you are going to upgrade don't play around with expensive 7 channel radios from the likes of Spectrum, Futaba and JR - go for the 10+ channels with telemetry from FlySky, Turnigy and FrSky.

Then again, if you have more dollars than sense and want to spend $10,000 on a big turbine jet then go for the $2,000+ radios from Futaba.

You won't be making any friends in the turbine community with comments like that......
