[@muteFPV]

No idea about the spring stiffness, sorry :)

[@dylandreisbach1986]

I was surprised when the manual didn't mention how to change the tension. This helped a lot.

[@muteFPV]

I am glad it did, thank you!

[@Harry_Go_in]

Thank you very much for making this video! I simply could not find this information anywhere on the web nor did youtube revies mentions which screw does what precisely

[@muteFPV]

I am very happy you found it helpful!

[@jonowillmer]

Thank you so much for doing this video the first 10 seconds are invaluable!

[@muteFPV]

Thank you very much!

[@RandoManFPV]

The best part is turning some these and having no noticeable difference made on my brand new controller

[@muteFPV]

That sounds very strange. If you loosen completely, does the stick flop freely around the center (meaning that the spring has gotten completely loose)? Which screws feel like doing nothing?

[@RandoManFPV]

@@muteFPV it did not. When I loosened every screw, the gimbal would stay wherever I left it. I took the controller apart and found out that the bendy thing that adds friction was making full on contact. The screw holding it was tightened to max. I just loosened that screw a bit and now all adjustment screws are working right.

[@muteFPV]

Thank you for the feedback and I am glad you sorted it out. This would be my suggestion, to open it and see the gimbals from the back side. Did the radio ship with the throttle ratchet engaged or disengaged?

[@RandoManFPV]

@@muteFPV Ratchet was disengaged. Friction bar next to it was maximum engaged. I'm wondering now tho. Is there a way to further limit vertical and/or horizontal travel? From inside/back of radio? I've got vertical travel maximum restricted from the front of the radio but it's still a bit much for me, and horizontal travel cannot be limited from the front/outside of radio. BTW I've got the tx16s mk2 JB edition specifically

[@muteFPV]

Ok I suppose they wanted to avoid throttle stick moving on its own weight so they preferred to put much more friction than necessary... As for the stick travel, you could probably use longer screws for the vertical travel. For the horizontal I have never thought about it... First idea that comes to mind is some kind of 3d printed gimbal ring that limits the stick movement exactly where you want. I don't think if any way that you can reduce the horizontal travel from the back of the gimbal but I will give it some thought. Shorter gimbal sticks would also help reaching the full stick deflection with a smaller movement.

[@MCsCreations]

Excellent tutorial, mate! Thanks a lot! 😃 Stay safe there with your family! 🖖😊

[@muteFPV]

Thank you very much, you too!

Thank you I've been looking for radio front labeling of this radio.

[@muteFPV]

You're welcome!

[@rickm1041]

Great video,.....could U tell me what size the hex heads are for the throttle friction, thanks

[@seantorcello3325]

Great video! Although how do we reduce the center "bump"? More so on the horizontal axis rolling left to right vis versa, there's a harsh bump in the center. Any advice? Cheers

[@rbOthree]

did you ever figure this out?

[@seantorcello3325]

@@rbOthree kinda not really. Been a while since I played with it, but I did loosen up the sticks and got thumb grippies. Changed the rates for my whoop and got use to it.

[@mhk1058]

That's brilliant thanks. There appears to be no way to lock in a new stick height?

[@muteFPV]

Glad you found it useful! There are 2 grub screws included with the radio, which you can screw to secure the stick ends to any height. The stick ends are 2-piece but I always add the grub screws anyway, unless the stick ends are screwed in all the way or I have used spacers or something similar.

[@dregeedub]

Like the music and overall presentation...👍 Never noted driver type/size tho......😁 Thanks

[@muteFPV]

Thank you very much. You are right, I had the footage in my other video and was 100% sure I had included it in this edit as well, my bad :( kzbin.info/www/bejne/pIfKqKusm9dknJY

[@muteFPV]

I added the necessary information in the video description, thank you once again

[@dregeedub]

Awesome! Thanks for that 👍🏁

Thank you for posting this !!!

[@muteFPV]

[@MrKillerHobbes]

Hey bro, does the radio come with a set of lighter tension springs or is it just a spare set of the normal tension?

[@muteFPV]

I am not sure, I have not tried them. I will ask around and get back to you.

[@MrKillerHobbes]

@@muteFPV thanks a lot bro! i feel like i am the only one on light springs coming from jumper

[@marcostivanello6189]

Hi I loved the video! I was wondering, is it possible to add the spring tension on the vertical axis of the left gimbal? I want to buy it but don't know if I can use it for both helicopters and trucks/cars (by adding or removing tension on the throttle stick). Thank you

[@muteFPV]

Hello and thank you! Yes, you can enable self-centering on the left gimbal, loosen its friction bar and adjust its spring tension. These gimbals are made so that you can change flying modes (have the throttle on the left or right), so both have a spring on the vertical axis ready to be used for stick tension.

[@marcostivanello6189]

@@muteFPV Thank you very much for your quick reply. So basically they are same gimbals and I don't need to add any extra parts? It just needs to be adjusted with a screwdriver and that's it? Thanks a million!

[@muteFPV]

Yep, exactly. Although I would probably not use friction at all if you want to switch back and forth faster. This way you will only have to engage/disengage self centering. I am sure there can be ways to hack the whole assembly and do it faster, without the need to screw/unscrew. It depends on how often you will need to do this...

[@marcostivanello6189]

@@muteFPV For the moment I'm setting up a Tamiya truck with which I want to play with my son, and later on I want to add a Trex heli. I don't need to switch fast, I will either use one or the other but I wasn't sure I could get the throttle stick to return to neutral (with the spring) the exact same way it does on the right stick. Well I placed the order and can't wait for it to be delivered..

[@muteFPV]

I am sure you will enjoy it, Radiomaster has done a lot of stuff right with the TX16S and the MKII is even better!

[@XloMotion]

Silly question In mode 2 should the left stick (throttle) have spring tension downward? I keep leaving the throttle up with unintentional results 😅

[@muteFPV]

The throttle should not have any spring tension to return on its own, when flying drones or planes for example. You can set this up with self-centering but you will have to constantly "fight" the spring tension instead of flying smoothly. If you are used to gaming consoles / gaming controllers, it will seem strange at first :)

[@SergioLopez-vu5lv]

is is the same for ag01 gimbals

[@D-Flap_FPV]

Thanks for the video

[@muteFPV]

You're welcome!

[@rickm1041]

opened up the TX 16s and the adjustable screws inside are phillips.....weird ...my radio I bought through Amazon 3 months ago and came with revision firmware 2.7....HEX HEADS will not work...hope this helps anyone with same exp. i opened my radiomaster up so I could clearly see the type of screw needed... hope this helps rick

[@muteFPV]

I hate it when they change things up all of a sudden... I prefer hex but most radios I had used in the past usually had philips head screws for ratcheting and friction..

[@UgoFPV]

I mate, just a question, did u changed the stick friction on your tx16s because I just bought one and the stick tension feel so high Thanks🙏🏻

[@muteFPV]

Hello! I always adjust the spring tension and throttle friction when using a new radio. Adjust them to your liking, try them out when flying and adjust again, until you are satisfied :)

[@UgoFPV]

@@muteFPV Okay perfect👌😄I just saw ur video about it!! Thanks a lot for helping us

How much do you have to turn the screw to get the rachet to engage?

[@chetankpatil4438]

So I have this radio and I am trying to adjust the gimbal tensions but the smallest hex screwdriver is too big for this. Any idea on the hex size?

[@muteFPV]

I show the hex driver in the video, if I remember correctly it is 1.5mm size. Some of the screws fit very tight to my driver, maybe the same is happening to yours too.

[@muteFPV]

My bad, I just realized that I had used the footage showing the hex driver in my other video: kzbin.info/www/bejne/pIfKqKusm9dknJY

Hey, I want to purchase a new radio. I want it to be a compact, gaming style radio, with the ability to attach an ELRS module on back. What would you recommend? My current radio is the X9D+ ( which I despise) and I have an R9 module that works fine with ELRS flashed. I want to keep the module, but throw the radio in the trash.

[@muteFPV]

Hello! I am not sure how many options you have for a gaming style radio that can fit a full size module on the back. Is selling the module and buying an ELRS-ready radio an option? Do you just need ELRS or also a 4-in-1 module?

[@adeyinkabrasil4426]

​@@muteFPV ELRS has everything I need. So you think I'm better off just buying an ELRS radio and just sell or forget about the module, right? The only problem is I haven't seen a compact radio with internal 915mhz ELRS....They're all 2.4ghz

[@muteFPV]

Ah I see, ok, I will give it a thought. I am personally a large radio fan instead of the smaller gaming style ones so I am not familiar with most of them.

[@adeyinkabrasil4426]

@@muteFPV Just went and asked the same question on the ELRS discord forum. It looks like my best bet is the Commando 8, which does have built-in 915mhz....So expensive though. Anyway, thanks for your help.

[@serval_fpv]

Hi so we cant adjust yaw and throttle stick throw ?

[@muteFPV]

You can adjust the throw for throttle and pitch by adjusting the end stops. There are no endstops for the horizontal axis of the gimbals (yaw and roll).

[@serval_fpv]

@@muteFPV yeah that's what I was asking.. shame that think I need different TX that has shorter throws..

[@mx118racer]

​@serval_fpv I just found this out too . I want shorter throw for yaw and roll . Weird how you can adjust throttle and pitch but not the other 2 .

[@BillyWitchDr]

What size of driver is needed to adjust the gimbal tension?

[@muteFPV]

You will need a 1.5mm hex driver. I had shown the driver in another video and thought I had shown it in this one as well but I did not :( I had included this information in the video description after another viewer pointed it out, sorry for the confusion.

[@BillyWitchDr]

How to make left gimbal self centring ❓

[@muteFPV]

Hello! Please check at 0:05, it shows which screw is used to engage/disengage the self centering on the left gimbal.

[@rickm1041]

I have tried a 1.5mm and it won't seat.... thanks

[@simon-fpv3d]

Hey, I have the same transmitter as you. When I try to adjustment the horizontal axis - nothing changed. Not on the right and not on the left side... Do you no the Problem? My Radio is brand new out of the box... Sry for my English, I am from Germany

[@muteFPV]

Hello! Are you sure you are adjusting the correct screw? You should feel a difference when making the spring tighter.

[@simon-fpv3d]

@@muteFPV Yes, I am sure. It is a little difference but mine is not so extrem loose then in your video…

[@muteFPV]

Sorry for the late response, I missed your follow-up. I would open the rear of the radio to see how far the adjustment screw goes and confirm if the spring is fully loosened or if something else is going on. Can't think of something else if it does not go completely loose like in your case.
