Real-Time Response
Double the resolution of PCM1024, the 14MZ's breakthrough PCM G3
2048 enables servos to pick up even the slightest stick movements.
It's the closest to actual real-time response possible, for
unprecedented speed and precision.

I assume the question is in the subject? Can you detect the difference between 1024 and 2048 resolution? Yes, but it will not matter to some pilots. Pilots that tend to fly precisely will be the most likely to notice some difference. The G3 2048 is availble on the 12FG, 12Z and 14MZ radios.

Only the most gifted pilots with very precision equipement (expensive digital servos and the like) will be able to see any difference.

Agree 100%. The vast majority of people flying RC planes if not told what they were using would not be able to tell the difference.

I don't consider myself "gifted". I have two planes one on 10x module 2.4 and another on Futaba12fg. If I fly both planes on the same day I can fell the difference. The 12fg fell very slippery. If I fly the 12fg for several weeks then go back to the 10x that plane fells very slow in response. I need to make a decision on whether to up-grade the 10x to a 9303 or move all my planes to Futaba 12fg. It makes it hard to fly both planes on the same day. Dennis

You're probably feeling the difference in the planes and/or their setups, not the radios.

I've flown the same helicopter (my Vibe50) with the same servos (8717) and power system (flight tech 6v regulated lipo) with a AR7000 and a JR921 with my x9303 and couldn't tell one bit of difference.

Andy,

Could that be because the 9303 is not 2048 resolution?

BillyGoat

Just wondering, could what you’re noticing be a difference in the gimbal feel rather than frequency resolution? Just having smoother gimbals and even different spring tension has a definite impact on flying.

I think the 9303 has 2048 with the R921 RX, but not the AR7000 as per JR's website, hence the comparison the poster was making. I can't verify this easily as I don't use JR transmitters. I believe on the JR side, the 9303 and 12X are 2048 capable and on the Futaba side the the 10C, 12FG, 12Z and 14MZ are 2048 capable.

There is more than just resolution that goes into stick response and precision, such as the quality of the servos, plane setup, TX gimbals, frame rate, etc. A lot of this will be subjective as preference may not match the technically better system. Differing plane setups, as mentioned in this thread, can totally skew any comparison attempted.

If your transmitter has a 3" stick movement (don't have a TX in front of me but I'm guessing it's in the range of 2"-3" for most TXs), then that means with a resolution of 1024, you must move the stick only 0.0029 inches, or 0.0744 mm to move to the next servo position. Even if you argue that between endpoint adjustment and dual rates you loose half of that resolution for full stick movement, that's still about 0.006 inches or 0.15 mm. This means that if you move your stick 1mm, you're going through somewhere between 7-14 resolution steps with a 1024 radio. Given this, what will 2048 really buy you in terms of feel? As stated above, I think delay, frame rates, gimbal smoothness, etc. all have a far larger impact on the "feel" of the radio.

Thats exactly right. The X9303 is 2048 when used with the 9 channel reciever but defaults to 1024 with any of the 6 or 7 channels recievers. So my point is, with a 6v lithium power system, and 130 dollar servos, I can't feel the difference between 1024 and 2048 on a helicopter that if there were a difference, I would think I'd be able to tell.

So I guess the 10C can also be 2048 if used with the right rcvr? Which one is that for the Futaba?
