OK, I've checked the roll deadzone on my TCA Yoke. If measured at the outmost of the yoke handle it's about 5 mm in total which IMHO is quite OK. I wonder what's the result on your unit? BTW- a dumb question: are you getting a big deadzone both in the sim and in the testing program? Typically the deadzones for all the axes are set quite big by default in all the sims. I've also checked TM Target- the deadzones there are set to 0 by default for TCA Yoke, so it won't help.

Hi @TomaszBartchie and welcome to the club! Honestly speaking, I haven't checked the deadzone difference after changing the sensor, also because the TCA Yoke is not my main one- I am usually flying with a Fulcrum (heavily modified), which in my opinion is well ahead of any other non-feedback yokes in the market. It might well be that TM used a deadzone to cope with a non-linearity of AH49 which is most sensitive around the center position. One thing that comes into my mind is that the possibility of adjusting the response curves to reduce the deadzone is built into TM Target software (if I am not mistaken, as I didn't use Target for quite a long time). Please give me some time to pick the yoke out of storage and play with Target- I'll be back with the results.

No they don't, and AFAIK they are not planning it. The metal grip (MCG Ultimate) is a 95-% replica of a real one which is used in SU-57 fighter; they didn't want to spoil the realism😀. Well, almost, as the real-life grip is plastic, not metal, but after the success of the plastic version (MCG/ MCG Pro) the demand for the metal one was high (inspired by the Thrustmaster cougar/ Warthog/ F-18). The SCG, on the contrary, was aimed at a much wider range of simulators, including the space ones- hence both the right-hand and the left-hand ones were available from the start of production.

As said in the title- when trying to connect, the message pops up: "Connected to: A320 L (or R) MCDU" and then the screen goes black. It works fine with all the other aviaCDU's I have licensed (Aerosoft A320, PMDG etc.). Prepar 3Dv4, aviaSERVER v19.2.4.0. Any suggestions on why it happens?

"High grade" are the key words here; and BTW, Warthog gimbal is all-plastic of much worse quality which is prone to breaking with heavy use...

Hi! 1. The calibration is explained in the AS5600 datasheet (Page 23- Angle Programming Through the OUT Pin). Please note that in addition to the red jumper that you can see on my pictures #7 and #8 you'll also need to connect the two upper leftmost contacts on the PCB to set the output voltage increase with a magnet clockwise rotation (I've just put a drop of solder there). The wire loop that can be seen on the pics is connecting the PGO pin to the ground to put the chip into programming mode; it should be cut off after the calibration. 2. I used PETG, but PLA or ABS will do as well. Regards, Sergey

Any similar-sized button will do, providing that it's of a momentary-switch type.

Hi Mauro, Almost forgot to mention another option- it's Bourns PEC11H series. 100 K cycles lifetime and the footprint is very similar to ALPS. Regards, Sergey

Hi Mauro, EC11K15XXXXX and EC11J15XXXXX are identical other than the PCB mounting method (pins vs surface-mount). Also the difference with "E" (original model) is minor in terms of interfacing with the unit's controller, which is proved by the fact that the "K" version is working fine in Wolf0's system. It means that the "J" will be OK as well. Great encoders, by the way- I'm using the K's in a DIY B737 EFIS module: a very good tactile feeling with a nice click

Well, the most extensive piece of documentation on ATR that I've found so far is the Aircraft Handling Manual. It's very detailed (including the chapter on the flight controls); still no mention of the yoke actuation forces. Good luck anyway😀.

The data for B737 is available (37+/-4 pounds for pitch, 12+/-3 pounds for roll at the yoke handle rim). I never saw it for the planes you've mentioned (except for +/- 52 kG for ATR 42/72 emergency CAP/ FO pitch channel disconnect).

Yep; actually your post was one of those triggering my investigation- thanks for that!😀.

After having acquired my own TCA yoke I decided to investigate the reason for the roll axis issues reported by some of the users. The first thing to check was the roll axis sensor as some of the users were reporting a strange dependency of sensor operation on the external magnetic field (which shouldn't be the case with a properly designed sensor). So after the disassembly I was very much surprised to see the roll axis sensor to be designed around a single AH49E chip which is a simple "old-style" analog Hall-effect sensor. There is a couple of issues with this solution: 1. AH49E is reacting to a magnetic field strength variation in any direction relative to it's body. When a small round diametral- magnetized magnet is rotated close to it, the field strength change is non-linear in relation to the rotation angle. Which means that the yoke's reaction to roll axis rotation is stronger near the center and becomes weaker close to the rotation extremes. Of course it can be compensated in the sim by choosing a non-linear response curve, but in my opinion having a sensor with a non-linear response and no internal compensation for it is simply not right. 2. The magnet is not too strong, so the output signal swing for a full side-to-side yoke rotation is mush less than a sensor power supply voltage. When the yoke internal calibration is performed, the signal is- well- 'amplified" digitally within a yoke controller to match the controller's reference signal voltage swing (from 0 to full power supply voltage). Unfortunately any "noise" (magnetic or electric) that might be induced to the sensor circuit/ connecting wires (that are quite long) will be amplified as well increasing the roll axis sensitivity to the external interference. 3. As AH49E is sensing any changes in the adjacent magnetic field strength, any external ferromagnet object near the back of the yoke handle will create a disturbance in the roll axis; the same goes for the stability of the internal magnet. In some cases this might require a yoke re-calibration. My solution to this issue is the replacement of a simple Hall-effect sensor by a different type specifically designed for registering an axis rotation. In my opinion the best DIY option here is AS5600 from AMS. The main features of the chip are: 1. It is reacting to a degree of magnetic field rotation in relation to a chip's upper/ lower cover. The signal is directly proportional to the rotation angle with a very good linearity. 2. AS5600 offers a very simple internal calibration routine which adjusts the sensor's output signal swing (from 0 to power supply voltage) to a full rotational angle required. This means a much better immunity to the external "noise". 3. AS5600 is not sensitive to the magnetic field strength variations so the external ferromagnet objects do not influence the sensor operation. Also there is no need of a periodic yoke re-calibration. In practical terms the option that I've chosen was to use the ready-made AS5600 board available from Amazon or eBay (also from AliExpress). It has all the external elements needed and the size allows to fit the board into the existing opening in the roll sensor base without the need of any mechanical trimming of either the sensor or the base. The board requires soldering one additional jumper to set the correct power supply voltage. Here is the set of pictures showing the mod. After removing the existing sensor and mounting the new board the new sensor needs to be calibrated internally but it's a very simple procedure not requiring any additional tools. Having done the mod I'm quite happy with the results. If any of you are interested, I'll be happy to provide the additional details.
