DX6i Control reversal problem

[Steve Houghton 1]

Just picked up my Baudis Banana slope soarer today and setting up the controls using the Orange RX with my DX6i. Here are the problems I'm having.

 

1. Ailerons working wrong way around. Selecting servo reverse makes both ailerons go either up or down. Left aileron is plugged into the aileron socket and the right aileron into AUX1. I have tried swapping the leads over to no avail.

 

2. Selecting servo travel adjust on ailerons only adjusts the right aileron travel.

 

Hellllllllpppppp

Have you tried reversing the Flaps and Ailerons

[Tim Mackey]

Check that wing mix selection is correct.

Try a combo of both swopping aux with aileron servo in rx socket, and also servo reverse on one or both channels. It takes a bit of faffing around, but it WILL work when you hit on the right combo.

I assume you are trying to get flaperon - so have you selected dual servos in wing mix.

If you wanna hang on a mo, Ill go and get my dx6i and a couple of servos and try things out?

[Steve Houghton 1]

I've managed to get both ailerons to move in the correct direction, and using travel adjust I can adjust the up travel of the left aileron, but not the down movement. I've done this by using a flap mix but I cannot see how to adjust that down movement, unless, mmm, could it be on the throttle stick?

[Tim Mackey]

OK lets be clear here.. firstly....have yousorted out

#1) as in first post?

[Steve Houghton 1]

Yes, ailerons now working in correct direction by adding flap mix.

 

MIX 1. Thro master -> flap slave act

 

 

[Tim Mackey]

Not sure why you have a flap mix just to get ailerons working - that is a fixed mix automatically assigned by selecting dual ailerons isnt it? Ill have play now.

Your servo travel issue may be connected with whatever position your flap switch was in when you set a mix - it may have been in the flaps active position, so restricting the amount of aileron travel available.

[Steve Houghton 1]

Unfortunately, the DX6i doesn't have a travel adjust setting for AUX1. By adjusting the flap travel adjust to 30%, (the same value as the ailerons), the up left aileron position is correct, I just can't adjust the down travel position.

 

Now what also happens is when the flap switch is selected on, the throttle stick gives me flap, and the left aileron gives me full down travel flaperon but the left is only the 30% which I selected for aileron movement.

 

Confused? Me too.

[Tim Mackey]

Lets start slowly, and work up one thing at time. Reset everything back to zero /defualt zerso, remove all mixes, trims etc, and JUST set wing mix to dual ailerons.

Then plug in the wing servos and sort out servo revere and assignment to get ailerons working. Im doing that right now on the test rig in front of me.

[Tim Mackey]

OK, for ailerons to work correctly I have

right ail =aux1

left = aileron.

 

no servo reverse required.

do you match ?

[Tim Mackey]

next, i set flap switch to 0, and ensure that in the flap screen I have 0 flap and 0 elev

Then I move flap switch to on (1) and dial in say..... +75. Both ailerons now move as flaps ( if they are up instead of down, then use a negative value instead. This will obviously depend on whether you have the control horns on top or below etc.

 

match ?

[Tim Mackey]

Now what do you want next?

Throttle stick to set flaperons, travel adjust throws wrong or summat....or what

[Steve Houghton 1]

Ok, I've inactivated both mixes, zero'd sub trims but have left servo reverse settings and dual ailerons has been selected. Both the ailerons are working in correct directions but max travel on them. My priority is to be able to adjust the travel, up and down of both ailerons. The right aileron isn't a problem as I can adjust that to what I like, but there is no adjustment on the left aileron which is plugged into AUX1 with no adjustment available on the tx for AUX1.

[Tim Mackey]

have you set the flaps up as per post above?

 

[Tim Mackey]

In travel adjust mode screen to adjust travel of aileron = use aileron TA, and for the "other aileron" use the flap channel travel adjust, as the DX6i effectively treats one aileron as a flap IYSWIM

[Steve Houghton 1]

Firstly Tim. Ails set as per your post but with normal servo travel selected, both ails go up. If I select ail reverse I get the correct travel direction

[Steve Houghton 1]

Just noticed also that the flap reverse has to be selected for the correct aileron travel direction, otherwise both ails go down

 

[Tim Mackey]

Sounds like you have the servos set in the wings differently - my test rig has them both orientated the same way IYSWIM. However, that shouldnt matter too much as servo reverse has that issue sorted.

[Tim Mackey]

Flap switch settings done ...?

[Steve Houghton 1]

Ok. So I now have ailerons and flapperons that all go in the correct direction.

[Tim Mackey]

Ok....so we are getting there.

Now - what do you want next mate?

[Steve Houghton 1]

The travel of the left ail is good, but on the right (flap) down is good but up is full and can't seem to adjust that.

[Tim Mackey]

In travel adjust mode screen to adjust travel of aileron = use aileron TA, and for the "other aileron" use the flap channel travel adjust, as the DX6i effectively treats one aileron as a flap IYSWIM.

On my rig here, travel can be adjusted both up or down on either channel with no problem.

ensure flap switch is OFF when attempting this.

Remember you need to nudge the aileron stick slightly to shift the indicator arrow into the direction you wish to adjust.

Ah got it . So now when I select the flap switch, the flaps just go down by the 30% that I selected for the ailerons. Can I get full travel on the flapperons?
