Chas Morgan Posted December 31, 2016 Share Posted December 31, 2016 hi My DX 9 is set up aircraft two airelons one flap. When the flap is deployed I want a mix set so that both airelons move up by a small amount (crow brake affect) Due to back mixing I find that one airelon goes up, but the other goes down, how can I overcome this please thanks.

Denis Watkins Posted December 31, 2016 Share Posted December 31, 2016 Hi Chas, is your aircraft a glider? As there are a number of wing set ups Quote Link to comment Share on other sites More sharing options...
Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 No it is a powered turbine aircraft, sorry i should of said. Quote Link to comment Share on other sites More sharing options...
John Lee Posted December 31, 2016 Share Posted December 31, 2016 It's easily done in the sailplane menu using the Camber System and Camber Presets in the Function list. I've only done it with two ailerons two flaps in the wing type, so you could do it that way & just disregard one flap output or try it with the two aileron one flap type. If you are using it in a electric or powered model you can still set it up that way and use flight modes to switch between throttle & crow on the throttle stick.

Denis Watkins Posted December 31, 2016 Share Posted December 31, 2016 Chas, please elaborate fully on the aircraft, and number of servos, it will save time Quote Link to comment Share on other sites More sharing options...
John Lee Posted December 31, 2016 Share Posted December 31, 2016 Your post has just crossed with mine Chas. Still try in the sailplane/camber system but select the control you want for crow (e.g. left lever) in the camber system menu & that leaves the throttle lever free.

Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 I have a servo for each airelon, one for the elevator, one for the flap/brake, one for the retracts, one for the wheel brake, there are two rudders (twin boom) with a servo for each, one for turbine throttle ie nine servos. it is set up as two airelons and when I mixed flapwith left airelon the right airelon moved dow, not up as i wanted this is due to back mixing page 23 in the manual.

Denis Watkins Posted December 31, 2016 Share Posted December 31, 2016 It appears you have used up all 9 channels Chas, and alternates would be a Y lead on the aileron ? Or the rudder? Where 2 channels may be freed up. With Aux 1 free, used for Aileron 2, you could slave that to Aileron 1 Edited By Denis Watkins on 31/12/2016 12:32:53 Quote Link to comment Share on other sites More sharing options...
Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 Thanks Denis, what if i set the wing type to one airelon and then slave the other airelon to it as a mix, then do two more mixes for the flap as master one to right Airelon and the other to the left airelon both for up airelon.

Denis Watkins Posted December 31, 2016 Share Posted December 31, 2016 You have cracked it. You are probably setting up the turbine by the book, but ask questions for the jet boys about fine tuning the control throws unless the book is reliable.

Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 Thanks Denis you rekon that way is okay and not too complicated it is all due to this back mixing see the bottom of page 28 in the book. i have no prob with the turbine or anything else it was just that on mixing one airelon to be up it put the other down due to this back mixing with no way to turn off back mixing.

Frank Skilbeck Posted December 31, 2016 Share Posted December 31, 2016 Just a thought, if you set the wing up as dual aileron with spoilerons/Flapperons then you could make the single flap something else (Aux1 or something) and then mix them that way. Must admit I haven't got a Dx9 though. Quote Link to comment Share on other sites More sharing options...
Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 Thanks for your replies all. Hi Denis It did not work, you are right I need an extra channel, but even with releasing one from the rudder, i am not sure that it will work.

Pete B Posted December 31, 2016 Share Posted December 31, 2016 Try changing your Flap mix setting from RAL to LAL (or vice versa) as per step 3 of this very useful instructional page for crow setup here Pete Quote Link to comment Share on other sites More sharing options...

Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 Pete b and Steve J Excellent article link thanks. My original set up was correct, but mixing flap with either left or right airelon made both airelons go in the opposite directions, but reading the article I realised the following: on my powerbox receiver there are two airelon sockets, but they are linked (ie rather like having a y lead!) and not independent all I had to do was to plug one airelon lead in to the Aux1socket instead then all was perfect as they were now independent and both went up as I needed with the crow mix on, so thanks very much.

Martin Harris - Moderator Posted December 31, 2016 Share Posted December 31, 2016 Chas - it's an AILERON! I'll have to make a New Year's resolution to be less pedantic but it's still 2016, I'm afraid! Quote Link to comment Share on other sites More sharing options...
Chas Morgan Posted December 31, 2016 Author Share Posted December 31, 2016 No that's okay the spelling was the least of my problems!!! At least you read my post even if you could not help with a solution. Don't change in 2017 but have a good year with lots of flying. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted December 31, 2016 Share Posted December 31, 2016 Ah you didn't say it was a Powerbox unit, depending which one it is you could probably have done the mix in the Powerbox receiver, and if it's one with built in gyros this is what you need to do, as now the flap mix into the aileron channel will in effect be an instruction for the receiver to make the plane roll.

Linds.W Posted March 6, 2017 Share Posted March 6, 2017 Been following this thread and am I right in thinking you can't get "crow" to work with the ailerons on a Y-Cord? Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted March 6, 2017 Share Posted March 6, 2017 Yes Linds, the crow would go opposite each other with a Y lead One up, one down You need the 2 servos connected to 2 separate channels Quote Link to comment Share on other sites More sharing options...
Linds.W Posted March 6, 2017 Share Posted March 6, 2017 Thought so will re-wire the leads no prob. with the 6chan. RX thanks Denis Linds. Quote Link to comment Share on other sites More sharing options...
