Not getting full servo throw on a flying wing? This is why

Few months ago, when INAV fixed the broken flying wing mixer, GitHub issue tracker, and RCGroups thread (www.rcgroups.com/forums/showt...) were flooded with problems: I'm not getting full servo throw after INAV upgrade. Here is (few months too late, I'm sorry) reasons why you might not be getting full servo throw and why this is not a bug at all.

Cool, thanks for that. Explains very well the poor servo throw on the bench!
Video by video I am getting a better understanding of how this works. Subbed for life.
Thanks for the help Pawel
A very full and clear explanation
I am comparing the flight characteristics of two identical conventional planes - one fitted with a well known plug and play FC, and the other fitted with INAV and Omnibus F4 FC
INAV comes out better - the plane reacts quickly to the nav modes and flies smoother and is more responsive
Keep up the good work

Hans
Thanks for the video,you make a great work.
Hai pawel..... I have a problem with my setup. My servo in elevator and aileron become very slow and wont go back mid position when i armed and in angle mode.
If i disarmed and angle mode still active, Those aileron and elevator servo become normal... In speed and they would come back to 1500 position.
Manual mode is no problem...
Any suggestion?
Pawel, thanks for making this video! So if I need to decrease overall control surface travel because the model is too agile while on manual mode I could then decrease the servo rates to 75% and test correct? I’ve already attempted to tame the airplane mechanically but it still needs further adjustments to make it fly how I prefer.
Will the integral part still be true if the flight controller is in manual mode?
Wow its like you read my mind. I'm having the same problem.thanks for video
What would cause the Receiver page in iNav to not show channels. It was working now it is not. FC board blue LED flashes continuously. Will not arm. Thanks
Thanks.I was looking for this info
So pleased I found this, three issues fixed in one evening. What did we do without the internet? (Some of us can actually remember)
Hi, I hope you can help me understand this problem. I have a glider with a matek f722 wing, it is the first time that I try to fly with a stabilization board of this level, currently, doing tests on the bench, everything works, (no errors and I can perfectly arm the engines) I have a solid signal from the gps, ailerons automatically respond to deflection, elevator responds to deflection but the only thing that does not move is the rudder :( :(
Please, give me an explanation. THANK YOU VERY MUCH
Should be nice to have some control during the installation to see on the bench if the control surfaces deflect the correct way when moving the plane around. Now the deflection is so little, it's hard to see if it is correctly programmed...
Test with MANUAL mode in Modes
He explained how to do that in the video. Remove the prop arm it and move the throttle up. Doing it in manual mode is not going to give you a reference for what it's going to do in rate mode. Because it uses two different rate systems. So only way is arming it with the prop off, moving the throttle stick up, then checking for deflection.
Really nice explanation. By the way I am a programmer and would love to help with the project. Where could I give you hand to help with the code?
Hello my friend i have question
No 1 esc motor
No 2 empty
No 3 elevator wing
No 4 elevator winf
Can i use no 2 to servo so. I can move servo for camera fpv for turn around. Thanks
No - there is no resource remapping in inav.
Thanks Pawel! I have a question about S800 config. The default 'template profile' in iNav 2.3 sets up 50% 'weight' on each servo axis in Mixer. IE: Servo 3 - 50% Roll, 50% Pitch. Servo 4 - 50% Roll, 50% Pitch. Is this correct, or should I change to 100% to get full throws? Thanks!
This is correct
@@FPVUniversity sorry, which is correct - 50% or 100%?
@@thedoble 50%, there is no bug
@@FPVUniversity great thank you!
Okay I understand that, but I'm not getting full deflection while I'm in the air. Don't know what I'm doing wrong but I can't even do a loop with my AR wing let alone a roll. I can't die because I can't pull out of the dive and it rolls so slow I have to do four point rolls with lots of down elevator when it's inverted of course there's no rudder so I can't do knife edge during the roll for a 4-point roll but it's so sluggish in the air it doesn't want to do anything I'm confused.
Are you flying in Angle mode?
HI Pawel thanks for sharing your knowledge with us i install a omnibus f4 v1 i nav ver 1.81 in my caipirinha and i noticed that the trims dont work (with no gps) if you have a solution please fell free to tell me thanks
You cannot use trims with inav, to trim you use 'autotrim' function. Moving trims away from zero will disrupt hold functions.
Thanks
Hey man thanks for your video maybe you can help me I've searched everywhere I set up an f 411 board on a standard plane and in manual mode I have no rudder I am just bank and yank but with the system on for leveling even holding it in my hand armed rudder works but I have no rudder control authority in manual mode which I can't figure out why I should have full deflection like all the other servers I assumed if you can answer this thanks or anybody else if not keep up the good work and I like that you're using whiteboarda lot easier to understand when I can see how you drew it out thank you
worked for me
i liked the old way this just confused the f out of me i have 2.6.1 on a plane i made and i have a ar wing sonic model 600m and i put 4.1 inav and i was like wtf why is my pitch not moving all the way
I just noticed this at the flying field. I don't know if I like this.
Sorry its no OKEY! Launch mode gives me so less servo throw, every time it grounds. If i start in manual mode, it climbs like champ! Destroyed 3 set of props.
I found that I prefer the saturation. Gives me greater control at slow speeds. Rarely do I need both full elevator or full airleron at the same time.
my servo just dont even work
same here....
Syed Md. You all need to connect your power wires coming from both servos the connect then to the power wire from ghe BEC.
