Funny you should ask that. I too wanted to know the "very" same thing a few years back when I acquired my A9x. I originally had an Aurora like my son. But then purchased my 9x and we put the two of them to the test. The Aurora is capable of 1024 resolution. The A9x is 2048 with the Optima rx's. The new Maxima rx. are 4096. As for the Latency, you will never know the difference as that is the refresh rate that the transmitter communicates with the rx. In other words, the speed at which each packet of information is sent. (This is the way it was explained to me) Anyone would be very hard pressed to know the difference between .11ms and .07ms. However, as I understand it, the faster the Latency the better. Especially if your signal has to travel a long distance. Such as a very high upline or a very far out circle. With your plane in your face, You will never recognize the difference. Less chance of signal degradation. Or worse, brown or black out. I had a light come on in my head. So...that is why there is a lag with some radios and not others. The lag from the time you move the stick and the time that the plane actually responds to the input. All Latency.
Ok, now the resolution. The amount of steps your servo moves with each step of your transmitter stick. For most of us, we are used to either the 1024 and 2048. 1024 steps of movement on your servo arm vs. 2048 vs. 4096 with the same amount of stick movement. (By the way, this is from end point to end point) Obviously with the more steps, the smoother and more precise your servos become. I wanted to know if this was real. I can personally tell you, there is no doubt in my mind that I can not only "feel" the difference, I can also see it. One of the tests we preformed was to turn on our tx's and rx's and move the sticks then watch the servo move. With the 1024 resolution you can almost see each and every step of movement of the servo arm. Almost "grainy" or "jumpy" from step to step. Now the same test with the 2048. Much less jumpiness and graininess. Quite a bit smoother. Then we tried the Maxima rx and also put the Gruapner MZ24 (both at 4096) side by side to the Hitec radio. Both were so glass smooth, you almost could not even hear them move. Let alone feel anything. But watching them was a true sight. Just like fluid...smoothly flowing liquid. Then blasting off with the same planes and basically the same setup. Shayne had a Great Planes Edge 540 with a DLE55 engine. I had the same exact plane with an RCG 50cc. Both were using Hitec HS7954SH servos. First we flew his plane with the Aurora and the 1024 resolution. Then my plane with the 2048. It was unbelievable the difference we noticed. Finally the last test last year was when we tried the MZ 24's with the 4096. You can not believe how crisp and clean the servos move. So do you notice the difference? We both did/do. This is one of the biggest reasons I hate to part with my A9x. So simple to program that a 3 year old can do it. Great Latency and superb when it comes to resolution.
