I have a Trex 600N and am using a JR 12X. Does anyone know how to slow the servos down during the flight mode changes? In other words, when I flip the switch from Normal to Idle Up 2, I don't want a massive jump in the pitch change. I would like to slow things down a bit.
Any ideas? I don't see it anywhere in the manual. All I see is the menu to slow individual servos, but I'm not sure how I would mix those.

Maybe you simply need to match your pitch curves more closely between modes.

My reference for this feature is my Futaba 9C. It has this feature and it can be slowed for X amount of seconds. Very nice feature!
My points are pretty well matched, but there is that little jump that is enough to make a spinning rotor head jump up or down very quickly.

If your points are matched except for the top and bottom should be no jump at all.Are your trim settings the same in all flight modes this has caught me at times.At what throttle/pitch point are you switching over.Yogi

Not sure about the 12x but the 9303 only does it in throttle hold.

newtek007,

I go much simper. Same positive pitch curve in all modes. I do not fly any F3C work, so I do not need a mid stick hover in normal.
I have +12 at top in all modes, 0 at center in all modes, and -12 in idle up. For normal and hold I have -5 at bottom, just to make it a bit easier when I chop power to idle on the ground.
So in any hover I can switch between normal, idle up and hold with zero pitch change.

I see you are in newport news?
Glad to see another heli pilot!

I've read the 12X manual, and I don't know any way to temporarily slow the servos.

I used to run different pitch curves and had this issue (I used to hover at half stick in Normal mode).

When I switched to Idle up, the machine would drop.

All of my pitch curves are exactly the same now, just the throttle curves vary. When switching now, there is just an RPM change.

This is what I'm doing now. I tried to run the pitch curves like in the Trex 600N manual where Normal and Idle1 were hovering a mid stick, but I am now putting in 0 degrees at mid stick on all modes. It seems to work better now. Also, i don't have to remember what mode I'm in as the stick will be the same in + pitch in all modes.

Well,well,well.....
Looks like I'm not the only one missing this feature. Take a look at the F-Mode Delay menu option. There it is!!!

I sure hope they offer to update the FLAGSHIP 12X with this feature!!!
