I ran into an issue late last night, I was setting the controls for the Dx6 and the elevons..I've ran into this before but can't remember how I resolved it.. when I tested the plane to check control throws , I noticed the ailerons were working in reverse and the elevator was Correct IE I push the stick forward it will dive, pull back and it will climb.. But right gets me left and left gets me right..? when I reversed the ailerons, the elevator reversed as well, of course.. In my book for setting up the Spectrum Dx6 it tells me to use the right servo in the aileron spot on the RX and the left in the Elevator spot so I did, and checked it again this morning, switching it around was no better solution.. I'm thinking I might have moved the servos from the underside of the Fuselage to the TOP side, this would definitely switch the elevators function.
On the underside, a pushing control rod gives you UP Elevator, on the topside it gives you Down Elevator, would this also fix my reversed Ailerons ?
My F22 V2 is almost finished!! Woo Hoo!!

Once you reversed ailerons try reversing elevator as well. You shouldn't have to move your servos

A good reference: The controls we use.
There are lots of ways to fix this, Can you see anything below that might be useful?
Hint: Servo reverser

Y-splitter:Its purpose is to make one signal into two?

Mixer:
Its purpose is to mix two flight control functions into one so you can send that combined single signal to one or two servos?

Servo reverser:
This allows you to reverse the servo any place in its connection circuit that is needed.

Servo cable W/Male and Female connectors:
This is used mostly as a servo cable extender.

Servo cable W/Male and Male connectors:
This is used to add mixers, gyros, and other things into a servo connection circuit.

Now try switching the two servo leads around.

What control surface setup are you ultimately trying to achieve?

Are you using two servos or four?

If you are using a linked 2x4 setup with your Dx6i, this thread has been of the most use for me in programming elevons in my Dx6i if that is what you are trying to achieve.

http://www.rcpowers.com/community/threads/elevon-set-up-using-dx6i-in-detail.5382/

Follow to the letter what jcrankshaw has in his first few posts of that thread and you should have the 2x4 setup if that is what you want, it has worked for me many times.

If you are using 4 servos and you want elevons and independent ailerons, my experience has been easiest with one on board mixer and two Y harnesses.

The 4 servo setup has you plugging one Y harness into the aileron port of your receiver. You then plug your elevon servos into the onboard mixer, plugging one plug of the mixer into the elevator port of your receiver and one plug of the mixer into one plug of the y harness plugged into the aileron port. Then you plug your aileron servos into another y harness and then plug that y harness into the empty plug of the y harness in the aileron port of your receiver.

You may then have to play around with switching the servos around in the mixer to get the control surface movement you want.

There are advantages and disadvantages to both setups. The 2x4 is simpler, just a mix in your radio, lighter as no onboard mixer or y harnesses. The main disadvantage I find with the 2x4 setup is drag and lag in the pitch if you are trying to do loops.

With the 4x4 setup, it is heavier and a bit more complex to setup, but loops are much crisper and smoother.

Just my $.02 worth and experiences with the Dx6i.

Cheers,

Scott

Luke you might be right, maybe a servo reverser is the answer..
nobody has answered me about putting the servos on the top of the wing ??
I think its what I did once before, but unsure of the results...
Maybe just setting the ailerons to the correct function, and learning to push forward on the stick to go up, is what I need to do
As a pilot, its instinct, to pull back on the stick to climb, pushing forward finds you taking a dirt napops:

Scott I must say, I'm honored!
I've been watching, reading and Learning so Very Much from this site, and all my new friends here have been so Helpful, I'm so blessed to have run into such a Great bunch of people!!!
Had to tell you, Thanks for everything!! you ALL do, and share so graciously!!
I have bought three plans now the T-50(was an Accident) I wanted the F-22, I was tired.
So then I bought the F-22 V1, and built it right off, took me about 8 hrs (paint and Madden ready) then I figured out what V2 meant, while reading posts and watching bunches of vid's.. pretty funny stuff..
So I had to have the V2, still have the V1 built, just needs gear..
I took my time with this one, it's bigger, requires a little more in materials and I was still learning and wanted to incorporate the new things I had learned, Like the KF3 Airfoil (How cool)
So here in another thread, I have my pics showing my plane complete with the KF3's added I still need to cut the water bottle for my Canopy and Fix this Elevon Issue
ok so My radio is the DX6 not the Dx6i and I'm using the 2x4 set up I believe(still learning bout that, 4x4 etc.) I have just two servos in Delta wing configuration, keepin it simple
I checked out the Thread you suggested front to back.. most of witch is about the 6i, However towards the end, was a post, suggesting a fix internally in the radio, by selecting the servos travel rates and moving it from say -125 to a+125 in effect reversing the servos that way, individually
I need to reread this, to make sure I get it, which I'm sure I do but...
You know the saying, "Measure twice, cut once"
sorry this turned out so long, just an excited "rookie" I guess..

Happy Contrails

Scott, it was (F1wannabe's) post;

Not sure about the dx6i, but on my radio I have the ability to set travel at 100 % or -100 %. If you can do this, reverse the servos this way.

The Servo reverser is a good cheat type easy fix, but it's not the best way. Set the controls up correctly. Don't pull a Jimi Hendrix on us. He played the guitar upside down and backwards, and was plagued with string breakage. Learn and do it the correct way. You should be able to fix this in the radio. We all had to sit down with the transmitter and figure it out. It will take you a while on the first time. As hard as it is the first time, it will be that much easier the next.

If I can't hide the servos in the fuselage, putting them on top of the wing is more aerodynamic. I always try to at least partially hide them, even on top of the plane.

A helpful hint: As a beginner, I liked my throws at 50%. 100% was way too reactive.

KTaber -

Sorry, I thought you were using the Dx6i, I'm not familiar with the Dx6. Yes, it does take some time and patience to get the surfaces to do what you want, but this time is well worth the effort, I have seen more than one maiden flight go badly due to something as simple as ailerons being reversed (one of them being my own...ops:, not a mistake I have since repeated...) .

It is a bit confusing regarding the terms "2x4" and "4x4", I admit to using the "4x4" to describe the "2x4" setup for a while until I was corrected. The easiest way I remember it is if I am using 2 servos to move four control surfaces, I call it "2x4", this means I have two pushrods connected to the same servo and the two control surfaces move in sync. On these setups, I like to mechanically reduce the throw of my aileron by putting the aileron pushrod in a hole of the servo arm closer to the servo.

You will notice I actually have my servo position reversed from what jcrankshaw shows in his thread, I did struggle to get this setup sorted out which was why I felt lucky to find the post I sent you as from this plane on I followed his instructions and it worked well.

There may be a thread in this forum somewhere on programming tricks for the Dx6, I know the manual for my Dx6i was not overly helpful in the "nuts and bolts" programming to get my surfaces to go the way I wanted them to.

I have never messed around too much with sub trims or travel adjustments much on my planes, not saying it won't be helpful to you in this situation, but I don't know have enough experience with them to be able to help out there.

I do fully agree with Luke regarding throws on your maiden or when learning, keep them lower to help prevent drastic "over controlling" and if you can apply exponential in your radio, I suggest applying some of that as well. The expo helps soften the control inputs around the centre of the stick and has helped me not be so twitchy. Nerves on my maiden flight makes me twitchy enough, so if I can compensate for this somewhat with my radio, every little bit helps!

I wish you continued luck getting your elevons situation sorted out.

Cheers,

Scott

this is simple to fix...swap the servo wires on the reciever and then go into the radio and reverse one channel at a time till it is right....as long as they are plugged in correctly it will work out if they are mixed if you do that..sometimes it takes a swap or 2 !
