For those that say a person can't tell or detect 10ms or 20ms latency,

I went from a 9C to 10C, very ordinary pilot and I did feel the difference.

I used to think the same thing about 10 or 20ms.But like STEFF, there was a NOTICABLE difference between a 6ex 2.4 and a 10C 2.4 when I switched.And believe it or not the 6ex was on the faster end of JKOS's test.

But man,that gunslinger was FAST

+1 did the same radio upgrade 6EX - 10CGH.

I haven't used the digital side of the RX yet Cant imagine that would be even faster.

Trivia,
The Russians lost one of their moon rovers due to latency. The earth bound driver of the remote controled rover ended up in a crater that it couldn't get out of becuase the driver didn't fully account for the 3 second round trip latency of the command out and video back.

My observation
I'm with everyone here. I also noticed a difference from my 7C to the 8FG. Its incredible... just to sum it up. It was so noticeable IMO that I had to change my flying style. Definitely took some time to get use too. Also, if I may add, when I was function checking my failsafe... the reconnect time is almost instantaneous .

i went from the 9c to the 10c i could really tell and i didnt at the time realize the speed of the 9c or 10c i really started to check in to the latencys after that so i know it wasnt a mental thing btw that video was wicked thats fast

You can't really. He could have an off day and you would never know he was 20ms off. He is just fast. I have several radios and they all feel differently. Has nothing to do with the latency though.

Are you speaking for everyone, or just yourself?... I think it's just you having an 'off' day.

Yes an average pilot with time on the heli can feel the difference.

simple answer is YES 100% IMO, going from a standard DX7 to say a 8FG is a big difference.

...Once upon a time there were Nitros, flybars and frequency pins...

My friend went from a DX7 Se to 10C with HS receiver and he noticed a difference.

I like the seat of the pants,different model radio comparisons.
The speed of processing in the average human visual system,sensory latency and reaction time are quite higher,normally around the 150-200ms mark. Of course an average driver would tell you thier car is quicker after installing a louder muffler

Believe what you will. If a different radio makes you feel more confident then certainly go for it.

I felt a noticeable difference going from my DX7 w/AR7000 to a DX7SE w/AR7600. I do believe, however, that unless you're really into timing critical maneuvers than you probably won't perceive the difference as well as someone who is. When I switched to the DX7SE I had to relearn the timing on a few key maneuvers, but once I got used to it, I felt more at ease with those maneuvers than I had ever been previously.

that is not latency. You felt 1024 to 2048 resolution.

I went from a 9C Super to a 14MZ, on the same heli ... You're saying they are the same in speed?....

Good luck with your latency beliefs.

besides resolution has nothing to do with reaction time ,im not green
dont let the minimum posts fool you or just because i didnt get into the latencey binge i just wanted some extra features and since the big switch to 2.4 fm guys were getting a little careless at times and i fly an f15 turbine and have recently sold my f18, so i feared being shot down more now than ever

If you listen to the man he said 2/100 of a second.Also If anyone has seen him performe He uses his fingers and slides them over the hammer so he isn't actually pulling the trigger and also he Is using blanks so that they will spread out. Far from 10ms or 20ms.Sure you will feal the difference In transmitting time from radio to reciever but honestly can you react that fast?No.The average reaction time for a human Is 215ms and still far from 10 or 20ms.

Believing that a top 3D piloting is only reacting when they are performing rapid, fast paced maneuvers is not quite accurate. As a classically trained pianist, I don't REACT while I perform a peice of music, I EXECUTE. Many of the same principals can be applied to flying R/C helicopters. At a certain level, the pilot is no longer reacting, only executing.

When would his execution of a manouver be timed In latency?Any executed move Is Instant as far as that goes.All of the top pilots not excluding one eat dirt.If they can act that fast they shouldn't crash any.
