consider the other features of say a stylus over a 9c or whatever the latest has-been radio is that may also be why it is that you are hovering better, extra latency is something you SHOULD go out of your way to put INTO a heli or radio for mowing grass,




this kind of flying is the weakest argument for reducing your control reaction delay or running out to buy a radio that has a faster feed loop. this is exactly the time when you NEED your controls to be slow and do exactly as you want (through buying time to see what is actually happening), not what your fingers are really telling them to do!

not saying thats the only way to park a heli on the deck upsidedown for a tank of gas, but it sure is easier than having to fly the thing through a lot of countercorrections.

Go for it KC. If you not intersted in reading what's actually being said then so be it. My comment was it was easily noticeable in these situations and for the record, I find that good not bad. And I can't see any logic in more latency being good? A bit like suggesting there should be a lag in a steering wheel or a car when you get close to the curb. Huh? You're hearing a different drum than I'm hearing that's for sure. So go for it!

KC,
If you ever really feel the need to slow down a Stylus, you can use the servo speed adjustment to effectively slow down the servos.

I agree that this is not exactly where low latency weights the most.
But you are confusing latency with the human perception-action-delay
That a human is slow in correcting unwanted movements of the heli does not mean that you WANT extra slowness to be added by the radio. The human slowness is a factor we humans have to struggle with, the radio latency is what we can get rid of.

Personally, I think there is a difference between lag time in the control loop (isn't that latency?) and the tightness (for want of a better word) of the controls. Old steering wheels on cars used to be loose---you had to move them a ways before there was a response. People had to move the wheels back and forth to keep the car straight. So give me less latency any time but lets not confuse that with control curves and how much response we want for a given input. The 9c has almost 6x more time to response than a stylus---regardless of expo or anything else---that's not going to ever be a good thing though less noticeable when less precision is required.

CAN SOMEONE PLEASE GET ME A PHOTO OF THE 12Z INTERNALS?

Wouter,
It ain't much different than the 14MZ.

The FX40 "brief" manual has a nice pic of one of the gimbals (which is the same as the 14MZ and 12Z).

John did you see the internal stick area of the 12Z ?

Interesting I wasn't even aware that there was a FX40!
Good picture of the gimbals there, it clearly shows that the sticks are still separate modules.
Also interesting to see that spacing is just as tight if not tighter than the 14MZ although I would expect this pulley Tx would be more spacey inside.

Is it so hard to get the rear cover off a 12Z ?

Doubtful, I just don't have one! Actually, you can't fault folks for not wanting to take their under-warranty radios apart. Probably the best thing you can do is ask Futaba service for their assistance (good luck!).

I have the pics

Opened up the 12Z ant the LHS and this is what I found:

I just upgraded to a 14mz from a 9Z and the difference was astounding! I also didn't believe I would recognize a huge difference between the two radios but the precision of the control is nite and day. It feels like speed sensitive steering on a car. You just think about changing lanes and it does it. If you are a stick banger you probably wont notice any improvment but for precision flying it is a huge benefit.

I asked Bax on RCUniverse but he just moved my post to the general section... In a PM he explained that he didn't have a photo.

He he ... you asked the wrong question!!!!

You probably should describe what you'd like to do and ask them to help with suggestions. They've seen the internals, so they can tell you firsthand if what you want to do is possible. Make sure you ASK for their opinion, otherwise you'll probably get the "we're not Futaba and we don't modify radios" line. An alternative is to call their support number directly (1-217-398-0007) and see if they can take some pics the next time they have a 12Z opened for service.

Thanks these are some very good suggestions. I will try again at the Futaba direct support at RCUniverse.

Also thanks for that picture of the gimbal module. Looks almost round now, so if there's just space enough to get it fixed in the new orientation it might work. But electronics screwed on later might change that.
