Hi Strong,
I have a Problem running my v-tail glider:
Operation with FY-Dos not involved is ok.(ch1 and ch2 of rx used)
Inserting FY-DOS (ail and elev. connected to ch1 and ch2 of rx, servos connected to S1 and S2) works ok in stabilized mode, but in Manual mode only one tail-surface mo ves for right/left or up/dn and both are in verted.
Do you have a solution?
Regards,
Bopa

Is there a golden rule for channel reversal? i.e. if its reversed in the radio, it should be reversed in the PC software too?

It seems, reading previous posts, that the only way to know if a channel needs to be reversed is if your plane loses control when switched into RTH mode :facepalm:

They need to be reversed in the PC and radio.

Put the DOS in manual mode, and make sure your radio is controlling the surfaces correctly. Then put the DOS in stabilization mode and move the plane though its 3 axiss and make sure the controls move the correct way to counter the planes movements.

If you point the plane up the elevator should go down. If you turn the plane right, the right aileron should move down. If you yaw right the rudder should go opposite direction. Make these adjustments in the PC and save to the DOS unit. And or read the manual as its all in the manual.

It very simple and relatively straight forward.

I doubt reversing in radio and the controller will work. As far as I have tested and experiment ONLY one change works. When reversing in 2 places, the sesond reverse will change back the effect of the first change .... MEANS NOCHANGE. Whatsoever, verify the physical effect on aileron etc.... after the first change.

They are independent in nature so they both need to be set correctly. I have setup 15 planes with DOS units. Make sure it all works manually, then do the reversing if needed in stabilization mode then go fly.

U need to setup the DOS when in stabilization mode as in RTH mode the DOS unit is trying to navigate the plane home left or right so not a good way to test the DOS settings.

Good news guys. I have my DOS flying reasonably well now.

I have set my X5 airplane and my X8 airplane gains to approximately

30 1 80

Yes the numers are insane but here is what I gather from both the manual and my many days of playing with numbers.

The first number is the max bank angle the plane will use to make a turn (not so much realted to a bank angle when it's on a path)

The second number you can think of it like how hard it tries to get back on track (cross track correction if you know APM speak) if it's too high it will try and hit the track at 90 degrees and that is not good because then it has to turn 180 degrees the other way to get to the track again... First set it to zero... it's not truely zero but zero is the lowest gain number. If it were truely zero then it would not follow along the track but rather it would go directly to the waypoint. Even with zero it will still follow the track.

Now you will notice a lazy S as it follows the track but no crazy back and forth 90 degrees to the path. So this brings in the third number. Incraease that and it will start to tighten up the S... too high and the plane will bank quickly to stay on course (good for maintaingin course but not good for smooth flight)

Now go back and maybe increase the second number to say 2. If the plane starts to over correct on the path again then you are too high... go back to 1 or 0

I was able to tune my DOS, Panda and Panda 2 all in one evening using this method.

The up wind path was excellent,
The path after the plane turns from cross wind to up wind was excellent
The path after the plane turns from cross wind to down wind was a long S but not too bad
The path after the plane turns from down wind to cross wind was again a long S but not bad.

I will now mess with the route stability and see how it applies to a flying wing (you would think from the manual that it does not apply to a plane without rudder but I found it really can mess up your flight path with a wing too)
