Everyone wants to bag and tag Spektrum as being a crappy system.
Yes, I know this is my first post on this website.
That being said, here's my 2 cents worth. I was out of the hobby for around 20 years and have just recently gotten back in. I started searching the Internet for info on all the new radio equipment. What's best, who's on top.... etc...
Simple fact of the matter is, if you have a brownout, it's got nothing to do with the receiver. It's the battery. If the battery doesn't have enough juice to run your electronics, then get a better battery.
Loss of signal: If your losing signal, it's usually in where you have your antenna run. What do you have around it that can block the signal from the radio?
Everyone that slams DX's by Spextrum, well, your just brand loyal. Every brand has its good/bad sides to it. Both sides come out to what the pilot wants to do with their plane. If you look, you can find just as much to slam Futaba, as you can DX.
Personally, I've got a DX8. I've flown my planes as fare out as I can see them and still maintain orientation with them. A few of them, using the off-brand receiver from HobbyKing.com and I have yet to crash and burn due to a brownout or loss of signal and I know that I'm flying the planes well over 1,500' from where I stand. (How? google maps, measuring from where I launched, to where I landed it (still under control) and then took off, to land at launch.
Most of the pilots where I fly use Futaba. I've watched them struggle with getting the receivers to bind because of other Futaba radios being on. Yet in every instance where a DX radio was being bound to a receiver, there was instant binding. I've also sat and watched them play with getting the servos and batteries plugged in to the right number by trial and error because Futaba doesn't mark their receivers other than 1,2,3,etc... where DX's are by name.... Bind, Battery, Elev., Stab., etc... Yes, once you know the channel number, it should be fairly easy to remember.
But every make of RC radio has its good points and bad points. To say anything different is just being stubborn and/or brand loyal. Choose the system that works best for your needs. Determine what you want to do and where you might go in the future and select the radio that fills those needs. With everything that's available today, it ain't that hard to do. Just make sure that you have the right electronics for what your using... i.e. if your flying a glider with no motor, do you need a BEC, or is your battery small enough in Volts to be able to supply the servos with the range they need. Most receivers can handle more voltage than servos and it'll pass that same voltage right to them. While they might not burn up, you can be right at the edge where the motor will be eating gears because it's over-torquing.
I chose the DX8 because of the features that it has that makes it simple for me to use. I was able to switch it to a MOD3, update it through the SIM card, I like the way the radio is programmable without having to screw with so many menus. Also, since I pretty much have to buy from hobbyking, the fact that I can get the Off-brand Spectrum receivers for less than 25% of the cost of buying them from a dealer... not to mention the fact that even the extended battery is available through them.
Living in Lima, Peru, I have limited access to what you have in the states or UK. This also effected my choice of radio systems. But having seen the struggling that pretty much every Futaba user here goes through, I can say that I am glad I purchased the DX8 and will be buying one for my son in the very near future.
The fact is, every radio system has its pro's and con's. None are above the other to any true measurable degree excluding what they are setup for. One brand may have more pre-sets for gliders but not that many for V-Tails, while another system is the opposite. This can be said for any system. It's what you want to/plane to fly that determines the radio, because when it comes to those features, thats where the difference is. One brand is better suited for one or two types of flying, but not all of them.
