neetz Posted September 9, 2019 Posted September 9, 2019 Hi all. Lately, i assume from my extensive helicopter flying, the Z axis on the throttle (the rocker pedals on the back of the unit) has a twitch to one side (right). Im afraid that i have "over used" mine. I think it can be few things: a) The potentiometer is becoming tired. b) The Spring that should center it is getting old. c) Both of above :( I would like to replace the potentiometer in it. Does anybody know, what type of pot they use inside that? I have changed USB ports for debugging. As the 'twitch' is getting worse, i dont want to set (any higher) deadzone, its getting silly. And i dont want to get pedals, ive used with those and get the job done even in the UH1. Or if you have a old TWCS throttle laying about with OK perormance on the Z axis and spring, i could consider buying it for spare parts. Thank you. :joystick: Im so happy that I found DCS, the free time i might have had - gone :suspect:
Sokol1_br Posted September 10, 2019 Posted September 10, 2019 I would like to replace the potentiometer in it. Does anybody know, what type of pot they use inside that? Normally potentiometer is the culprit. Before replace try clean the old - inside, spray their case outside with contact cleaner is "placebo". The model used is probable CTS series 251 - 251B12T104A2NB is used in twist of T.16000M. https://br.mouser.com/datasheet/2/96/251-1147030.pdf
backspace340 Posted September 10, 2019 Posted September 10, 2019 I've had two TWCS throttles so far and both have had the same thing - looks like the sensors in the paddles are just trash.
neetz Posted September 11, 2019 Author Posted September 11, 2019 yeah, well, today the slew axis died as well. will keep the old one for tinkering and trying to upgrade but just to keep me flying, i ordered a new one :/ :D Thank you for the replys. Im so happy that I found DCS, the free time i might have had - gone :suspect:
slickdevel Posted September 19, 2019 Posted September 19, 2019 Today my Z axis began giving me rudder inputs that I was not making. Only 3-4 months old, unbelievable!
erniedaoage Posted September 19, 2019 Posted September 19, 2019 I got the same problem, but i use the rocker for zoom. Usually WD40 gets rid of it for a couple of days. You can try to clean it or get a better/more durable pot instead.

Arikaj Posted July 1, 2021 Posted July 1, 2021 Well I am joining you guys. Twitchy Z axis and now the slider is slowly dyng also. 1
rel4y Posted July 1, 2021 Posted July 1, 2021 (edited) I have designed a contactless sensor replacement (magnetoresistive) for this pot type, which will solve spiking/ worn pot problems once and for all. Earlier I made a version based on an Allegro hall sensor, but that was more of a hassle than what it was worth. Only thing is I designed the axle to fit the Cougar & TM16000 sticks which have different shafts. I dont know what shaft type and length the TWCS throttle has. Could somebody send me pictures and/or check shaft diameter and length? The shafts are either ~4 or 5mm in diameter and 12 or 15mm long.

Rocho Posted July 1, 2021 Posted July 1, 2021 I am joining to the club too. My TWCS is relatively new but the z-axis is only responsive to left side. Since I have pedals and I don't need it as a rudder, I use this axis as two buttons by means of XPadder, left movement-button one and right movement-button two, but now I have had to disable the right button.

Would be this video helpful? Are you somehow able to get the measurements? I do not want to disassemble my throttle apart from the base since it is still under warranty. I am waiting for a heads up from Thrustmaster if there is no warranty void sticker or such and if I can try to clean the potentiometer.
rel4y Posted July 1, 2021 Posted July 1, 2021 Wow, just saw the throttle axis pot is SMD mounted on the PCB, thats a dick move.. Sadly, from this video its impossible to tell what pot type is used in the rocker mechanism.

TOViper Posted March 11, 2022 Posted March 11, 2022 Same here, after 2 months of flying mostly helicopters the z-axis (used for pedals and rudder) got a little crazy, it produced spikes (mostly on CCW rotations). My currently working solution: .) Dismantle the thing according to Arvey Jay's video: https://www.youtube.com/watch?v=gVzhEgHS4bA .) Pull the potentiometer off the top to have it loose (didn't touch the cables) .) Rotate the knob of the poti to full left and right a few times, thereby pulling and pushing it (but just very carefully) .) Put back all stuff and re-assemble the stick .) Spikes are not there anymore Yeah babe. Let's see hot it goes ...

TOViper Posted May 29, 2022 Posted May 29, 2022 Hm, after flying a few hours more, the initial problem with the spikes is back. So the poti is garbage. Pure garbage.

Mr. Farknocker Posted February 3, 2023 Posted February 3, 2023 Someone on Reddit says this pot works: https://www.mouser.com/ProductDetail/774-251B12T104A2NB. I just ordered it and will report back if it works for me.
