Dsx9 on Trex 600n one control still reversed hayelp!

[Gazzer1uk]

Folks,

The answer is staring me in the face but just can't see it! On a fly barred nitro pro trex 600 So setting up DSX9 to Spektrum Rx Futaba servos.... 120 deg 3 servos set up but I can get either forward or back, or pitch increase or decrease working in the correct orientation but not both at the same time. I reversed various configurations of servos but would always end up with two controls ok and one reversed. I swapped aileron and channel 6 around but ended up in same issue. Didn't change elevator servo.....

its me me but what have I missed?

cheers,

Gaz

Use servo reverse until the swash moves up / down with the pitch stick.
Then use swash reverse to get elev / ail & pitch correct directions.

Aileron and pitch plugged into wrong channel Gaz

Hey buddy.

In the swash plate mix menu, you can have the values as positive or negative values, this reverses that channel and you can change aileron, elevator or pitch.
An example is, say your two aileron servos are moving in the wrong direction with stick input (rolling right on a left cyclic stick input) with a positive value, make it a negative value to change it.

Have you tried negative pitch mix e.g. -60, under the swash mixing?

For example:
ali +60
ele +60
pitch -60

I think it's fbl with beastX chaps

is it not meant to be 1 servo normal on spektrum?

Only for FBL

Hi guys,

This one is Flybarred I am setting another one up that isn't and Wavey has been really helpful on that journey!

OK, so I'll have a go later I didn't realise there was a swash direction, I think that will solve it!!!

I'll let you know! Thanks guys!

Hey, you're right Ian. I must just be blind to the words flybar, my thinking being why would anyone want to do that Sorry Gaz

[Gazzer1uk]

Whatever I am doing wrong it's still staring at me in the face!

So, got things sorted I thought, let me just check I am right....

This is a flybarred Limited Edition head on a Nitro Pro model.....

When I push the throttle stick up, the throttle moves correctly and the swash plate rises.

From the rear of the heli, if I put a left aileron control, the left part of the swashplate drops and the right part rises..... if I do a right input, the right side drops and the left rises.....

If I pull the elevator stick back, the rear of the swash plate drops and the front rises, and vice versa.

I have +60 deg pitch on the swash mix and -60 deg on ail and elev...... I think ch2 was normal ch3 and 6 rev.

I set +10deg at full stick, and -5 degrees at bottom with +2 at mid way, at least so I thought.....

I did buy this off ebay by the way......

In the garden, engine started quite quickly, revs raised but in the glinting sun, when I started to move the rotor disc, it was weird.... it looked like on forward stick elevator, the rotor disc was going left and forward, and in fact each control input seemed to be going awry. I stopped, checked and gave it another go, with exactly the same results..... I was also not sure the pitch was actually doing what it should, the smoke from the exhaust "seemed" to be sucked upwards whereas I would have thought it would be pushed down as pitch was engaged....

So, very odd...... should I just start again from the beginning, can anyone tell me what their settings are on the TX and which servo is plugged into to which servo etc?

Again, it will be really obvious and staring in the face!

Cheers,

Gaz

If at first you don't succeed..... so, got a bit of time today, started at the beginning again, reset pitch curves etc, etc, I also noticed the flybar was consitently falling to one side as if unbalanced and discovered one paddle was 4 mm shorter to the end..... sorted that and did an unmanly reading of the manual.... so set neg pitch at -4, 50% at + 5 and 10 deg at the top....... odd, all pitch on the blades were wrong....hmmmmm, the only difference, I have glued a small spirit level on my pitch gauge, but I used a table that was not level, and spent time making it level.... I wonder whether the previous table was not level...... Anyway finished it all, fuelled up and headed to the back garden..... for those rightly concerned about safety my garden is 70 x 100 foot, and nothing in the centre.

Well she flew, but I had real issues with tail wag..... main blades are not true yet, and throttle curve pitch curve needs a bit of work, but airborne, woo hoo.

So I think somehow in the pitch curve I had off things happening hence the issues of it not looking like it was doing what it should, today apart from the wag, seemed all quite good normal.

I shall now leap over to the JR G770T thread to see how to stop wagging!!!! It was very, very destructively potentially wagging, but hey progress!!! Now need to go back to the flybarless version too.... I could have 3 helis to amuse myself with shortly!

Cheers,

Gaz

When the heli is on the ground and you put in cyclic to rock it on the skids, the disc tilt always looks a bit squiffy - don't really know why, but I've often noticed it.

[Coxy]

this may sound stupid? but have you checked that you have no trim set up in the radio on the side ratchet switches - I have only found this out through a recent experience
