3GX question re. pitch

[Three6ty]

Hi,
Just so I know if I've done this right. Set up the 3GX in DIR mode as per manual with 12 deg collective and 12 deg cyclic.
When I fly I don't want 12 degrees of cyclic. Say if I wanted 9 or 10 would I now just simply reduce my swash mix numbers down to get the required pitch?
Or do you set the pitch you require during DIR mode? Thanks.

You would set a +/- 12 in dir mode, the set your normal pitch curve to something like -60% +100%, then in idle up set -100 +100 in pitch curves.

Yeh just reduce swash mix to get the cyclic you want.12 is pretty scary.I usually run 8 degrees of cyclic.

Hey.

While in DIR mode you are teaching the 3GX the maximum available pitch and cyclic ranges by adjusting your swashplate mix values up or down accordingly.
However outside of DIR mode, your swashplate mix values tell the 3GX at what rate (in degrees per second) to allow the model to flip and roll at. This can be seen by viewing the movement page in the pc software and adjusting the control rates. So you can adjust these values out on the flight line to obtain the flight feel on cyclics that you like.

While having enough cyclic throw to allow the 3GX to make the model perform quick and accurate stops in aggressive manouvers is a good thing, 12 degrees on cyclic is a bit too much. My worry was of stalling the blade, should the unit throw in a lot of cyclic with a high collective pitch setting to.
On my own models I always used to use a maximum of 10 on cyclic, but preferred +-12~14 collective pitch.

Hi,
Thanks all for the advice. Much appreciated. However, I am now slightly confused. I understand that in DIR you are setting up max throws etc. But I have 3 replies above for tuning the cyclic after DIR mode to my liking. One stating that I adjust my cyclics using my pitch curves. One stating that I should use my swash mix and lastly one that says change the control rates in the pc software. Is one right or will they all effectively achieve the same end result?

My post is related to your pitch, not the cyclic. The cyclic range should be set from your swash mix, I run 8 degrees of cyclic.

I think coolice means that you can see the effect in deg/sec in the software as you change the swash rate.
It's no good trying to measure cyclic pitch outside dir mode, as the cyc will always go to max as the heli is not responding as it's not moving.
Drop swash mix down by 10 points and just go fly it Rich, the worst that will happen is that it will flip too fast. Land, lower swash mix and go again. It won't make it's any different to hover.

Thanks Si.
After reading Coolice's post again, I see what he's saying. I just read it wrong. Long day.
Bottom line is, I now understand that you can play around with the swash mix out on the field without worrying about the max settings I set up in DIR mode

Hey buddy.

Yep, spot on you've got it.
