"DX6i"

[Tande]

For those of you using the DX6i TX---What am I missing?---When I use sub/trim to set all three swashplate servo/arms at 90* at half throttle/pitch stick, then adjust swashplate linkage to level swashplate (using swashplate leveling tool)---THEN run throttle/pitch stick full/up & full/down, the servo travels are not exactly matched at each end, resulting in a swashplate "Tip"---Not a "Lot," but should we be able to adjust this "Out"?---Or is this not possible with the DX6i?---:arggg:

[LockMD]

if you are adjusting for 90 at mid stick you are in idle up mode, yes?

[joediamond]

Adjust the individual servo endpoints to get the swash level at zero and full stick. The Finless videos on CCPM setup cover this very well.

Adjust the individual servo endpoints to get the swash level at zero and full stick. The Finless videos on CCPM setup cover this very well. When I go to the "Travel/Adj" menu, the only servo to respond is the pitch servo---the elev & aile servos do not---Again this is with the DX6i---

Yes it is possible to have the swash plate level at both ends of stick travel. Here's how you do it.


Disconnect the motor, or someone might get hurt.
Get the swash level at 1/2 throttle. You kind of know how to do that. Here's an easy way.
Change the pitch curve on idle-up to 0-50-50-50-100.
Put the stick mid stick.
Level the servo arms
Level the swash with the pushrods
Now, go to full pitch
Using the Travel Adjustment, level the swash. You may have to move the elevator or aileron stick a little to get the arrow pointing the right way to adjust.
Now do negative pitch the same way.
Check the swash is level at mid stick, full positive and full negative.
Check for 0 pitch at mid stick and zero both blades. This might be a good time to level the seesaw by raising or lowering the swash with the servo pushrods and then set the blades to 0 pitch.
Check your pitch at the end points. +/-10* is good
This is where it gets tricky. If your pitch is more negative than positive, do you make a mechanical adjustment or an electronic adjustment. My theory is you make mechanical adjustments to get it as close as possible, then make electronic adjustments to fine tune.
Pull the head and check the swash again.
Put the head back on and recheck the pitch
Reset your idle-up throttle curve to 0-25.50-75-100Here's the neat part. If you did it right, it will be in trim right of the board. Track your blades and you are done.

You may have to move the elevator or aileron stick a little to get the arrow pointing the right way to adjust. I just went & tried that---Thats what I was overlooking---Thanks so much to all who responded!---& of course to you, skigolfmike :thumbup:

No this in normal flight mode



In normal flight mode everything should be 90 at zero stick not mid stick

[LockMD]

WOW Mike, such detailed info :thumbup:

[skigolfmike]

I can put in new servos and do all that in 1:30. More flyin, less BS.

Again, do you guys keep a log/journal on this. You da man! :noteworthy

[skigolfmike]

It's all in my head. This stuff isn't that complicated. LOL

LockMD,

In normal flight mode everything should be 90 at zero stick not mid stick

I don't think that is correct.
I guess it depends how your normal mode pitch curve is set up, but since I have some negative pitch below half stick, and I want the swash to have full travel in both directions, it would be better to have the servo arms at 90d at center stick.
And setting it up level at half stick will transfer over to idle up as long as at full negative pitch, -10, the swash is level.

Anyone, please feel free to correct me if I'm wrong.

[LockMD]

I like that wolf!

that is what I am trying to do to help with winds wanna try constant head speed with some negative pitch so the throtle stick basically just changes pitch and not head speed

I will try asap but not with winds, like it has been here the last 3-4 days and expect more the next 3-4 days.

I want to combat the winds but if I am wrong and test in the winds, I will loose it and have no way to bring her down.

Just by changing the throtle curve as Mike suggested gave me much longer times (even in the wind) I may not go in that direction anymore. But still curious.

[Wolfpackin]

I tend to go with whatever Finless Bob says.
His recommended, beginner, curves are:
Throttle= 0-50-80-90-100
Pitch= 40-45-50-75-100
I really liked the throttle curve for several reasons.
I'm at extreme altitude and I knew that a higher headspeed would help with lift. I've also come to learn that this increased speed helps with tail authority which I needed as well.
I've actually upped my curve from there to 0-40-85-92.5-100. Above half stick this matches the stock idle-up curve which will make for a smooth transition.
The pitch curve above gives smooth and linear pitch above half stick and just enough negative pitch (-2) to bring her down in wind.

Of course you don't live at my altitude, very few people do, so you have the ability to play with lower throttle curves if you want.

I guess I went a little off topic there.
The bottom line for me is I want my setup with full throw/collective swash movement in either direction even though I'm not using full negative pitch (-10).
I want to be set up like a pro even though I may never get there.
