I'm not entirely sure why you would want to do that.

To keep the quad hovering a specific static distance above the ground, you're always going to need to be constantly making very slight adjustments (feathering) the throttle to do that. These type of quads aren't designed to hold their own altitude, and with propwash plus other external factors you are going to have to manually keep making minor adjustments to the throttle in order to hold vertical position as best you can. Also, as you roll or pitch the quad left, right, forward or back some of the upwards thrust will be used to provide directional velocity which results in you losing some of upward thrust, so as you manoeuvre, you have to adjust the throttle either up or down slightly to compensate for this.

I don't really see how having the throttle on a rotary knob in addition to the stick is going to help. If anything it will just make everything more complicated than it needs to be and I think it will just set you back with learning how to fly a quad properly. Also, even if you could do what you are asking, you would need the stick and knob to remain in sync with each other. So when the throttle stick is moved to the bottom, the knob would also need to automatically move to the fully anti-clockwise position, and when the throttle stick is moved to the top, the knob would also need to automatically move to the fully clockwise position. Likewise, if you turned the knob fully anti clockwise the stick would also need to automatically move to the bottom, and if the know was turned fully clockwise, the stick would also need to automatically move to the top. The Taranis can't do this. You can do some quite clever stuff with OpenTX mixing but not what you're asking for based on the knob and stick sync requirement.

Unless of course I've just completely misunderstood what you are trying to achieve Big Grin

I think the best advice you can probably be given is just to get more stick time in until the muscle memory eventually takes over and it becomes automatic. And if you're not already using a simulator to get some practise in, then now might be the time to start thinking about that Smile

you are very very good with words.. whew you explain everything so eloquently and understandable... THANKS!! okie.. kool.. one reason i was asking to do this was because as of that post i was actually inside betaflight adjusting my leds and just exploring around trying to figure out stuff.. so when i went into the receiver tab, i noticed that the colored lines representing roll pitch and yaw were settled on 1500 nicley but when i noticed that throttlewas a lttle off i went onto my tarannis and adjusted the mixing thingee till it settled at 1500 also.. i also did some other things too like slid a slider i didnt know what it was just to figure out what it did, but nothing major... SO.. ever since i been flying this quad, in the configuration it is in now (or was) , i always noticed that when would raise the throttle one notch, just ONE notch, it would keep revving up on its own even while still on that notch.. and vise versa.. the throttle never would stay still even while on a notch.. so that is why i wanted to use that dial switch.. BUT after i posted the above post and logged out of betaflight, whatever i had done in betaflight and im not really sure what that was, the throttle now stays stationary when i leave the stick on a notch.. (they ARE called notches right lol) but anyway, all is good now, i just had to adjust something that im not sure what it was but the throttle seems to be working now and not revving up on its own.. i mean, it wouldnt do it FAST on its own, but i would rev past where i wanted and i was always having to adjust the throttle..but anyway, thanks again man have a good night  :0)


   P.s i should would like to know what it was that i did in betaflight that stopped the throttle from doing that though

Want the technical explaination? Because the copter isn't moving. If there is no movement, you have no gyro input. With no gyro input, there will be no positive (or negative) error signal to add to the I term.
The I term is additive. As error is measured, that error is added to I. If error persists, I grows. If error STOPS, I STAYS. Only at NEGATIVE error does I shrink back down again.
Since your copter isn't flying, you are only giving it half of the error (your stick input tells the copter to rotate x degrees a second, the copter is rotating no degrees per second at all, hence you have an x degrees per second "error" measurement) and I will grow. In the air, the copter would start rotating, error would shrink, and eventually become negative and decrease the I term back.
So perfectly normal.

okie.. brand new throttle question.. ya know how the throttle (the left stick) moves up "notches" well.. recently, i dont know how, but somehow, i had it going just nicely.. like if i move the throttle up a notch.. the throttle rises a little a STAYS there.. it only goes as fast as i let it.. THAT's THE WAY I LIKE IT !!.. BUT for some reason.. i dont know how, if i move the throttle up a notch and let it go, it keeps revving up on its own !!!! i cant stand that !! what causes that and how can i turn it OFF !! i mean its like if i move the throttle UP a little and just let it SIT..it just keeps going faster and faster ON ITS OWN!!! i dont want that.. i just want to have complete control of the sticks ... no modes , no nothing.. the only thing i want is that it stays level... if i turn LEFT...i want it to STAY left.. if i move the throttle UP on a few steps and STOP.. i want it to stay there.. how do i turn that off.. i currently have NO MODES on but ARM mode on AUX 1.. i remember awhile back i had this same issue with the throttle but somewhere somehow, i stopped doing that revving on its own and now its back.. whew i dont know what to do !!! thanks all...

Not sure about the revving up by itself, but throttle needing constant adjustment when hovering is normal.
If you connect to Betaflight and go to the receiver tab , do the values shown remain stable?

I noticed in an earlier post you spoke of adjusting something to get throttle to stay at 1500ms. Throttle should read 1000ms when down and 2000ms when up. 1500ms is the centre point and doesn't really matter for throttle.

When you say the props go faster and faster do you actually mean that (i.e. can you audibly hear them continue to speed up more and more), or do you just mean the quad continues to ascend, because there is a difference. If it's the latter then that is what is supposed to happen until you bring the throttle back down again to level off the ascent.

Maybe you need to post a video that tries to show what is happening.

Also keep in mind that all the flying we've seen you doing so far is hovering around slow(ish) only a few feet off the ground. You are going to be getting a lot of prop wash and some of that is going to have an effect on what the PIDs are doing to the quad.

Kaity mentioned it before, but are you also sure you definitely don't have AIR mode switched on?

hey, also... now.. when i want to yaw left it GOES RIGHT... when i move the stick LEFT it wants to move RIGHT... AND it is VERY VERY touchy meaning that if i BARLEY pitch FORWARD.. it almost wants to FLIP forward... WHAT HAPPNED ? i DO admit last night i tried to turn on different modes like angle, and horizon, but i immediately didnt like that so i deleted them and turned them off in the modes tab... THAT is when all this started happening.. NOW i cant get it to where i had it.. im gonna go check and see if air mode is on.. hopefully that is the problem.. thanks

If you want to see what settings you have changed from their defaults, connect your FC to Betaflight then go to the CLI tab and run the "diff" command. Anything that appears are values which you have changed.

If you're not sure what you might have messed up, you might be well advised to reset all Betaflight settings back to their defaults and start again. You can do this by going to the Setup tab and click the yellow "Reset Settings" button, or if you're in the CLI, run the "defaults" command.

Make a habit off typing 'diff' or 'dump' in the CLI and then selecting the save to file option (in the bottom right corner) before making changes. This gives you a back-up. You can later paste this file back into the CLI to restore it.

hey just got home.. couldnt wait to get here.!! anyway.. i think i figured out some of the problem but i dont know HOW to fix it.. it is in the tarannis x9d.. i messed something up in there.. when i move the stick to the RIGHT.. the yaw part on the tarannis screen moves in the other direction, it goes RIGHT ... how did i reverse this and how do i fix it ? tell ya what.. ill make a video tonight.. thanks for the info on the diff command gonna go do that now thanks a million   !!

okie.. michael here again.. now just to let yall know i have fixed the yaw problem thanks to snowleopard..(thanks again snow :0)) but anyway, back to the throttle issue.. to update real quick i have been confused about why my throttle seems to go faster and faster by itself when i only want it to go as fast as i WANT IT TO by the control of the stick.. BUT SOMEHOW, this issue seems to FIX ITSELF.. i'm just trying to figure out how and why and what is making it do this ? it's not nesceraily a bad thing i now realize, but if i could just figure out the cause of this.. i went into betaflight a little while ago after snowleopard helped me with the yaw issue and just adjusted the receiver tabs to match 1500 so i dont drift any, and then saved and that was all.. so i go out and ARM and i get normal throttle going only as fast as what notch i am on.. SO.. here is the video of that: p.s. in time, i want to learn all about MODES.. apparently i learned to fly this thing WITHOUT any mode of any kind !! i didnt even KNOW that lol !! but anyway here it is :
