I have a Logitech X52 Pro HOTAS. It comes with 2 detents by default, one at 25% and the other at 75%. Since the 25% was messing with the fine-control at the lower end, I decided to remove them.
The downside to that was that I no longer had the afterburner detent. It's really useful because you can without effort go to mil-power. Without one I am constantly sliding into AB and trying to find the sweetspot of mil-power.
Other HOTAS setups have solutions for that, for example this neat one for the X65. There's nothing for the X52 though. I tried applying solutions found for other HOTAS. Solutions which didn't permanently modify the throttle. I tried magnets, some thermoplastic molded into custom shapes and this zipper storage bag solution. It didn't work, because it was too rigid and wouldn't give in being pushed into the plastic enclosure and would just slide off, taking the tape with it.
The solution
After weeks of trying to come up with something, I tried using double-sided tape which I ordered for my attempts with magnets. It worked. Why? Because the tape had a spongy layer which provided physical feedback, but eventually caved in and got pushed down. I think using anything spongy would do the trick, but I liked the extra adhesive properties of the tape which prevented it from ripping off.
The needed materials were: double sided tape (I used Tesa Powerbond Extra Strong) or something spongy, regular tape and scissors.
Here's a video of it in action. I adjusted the AB zone in Falcon BMS and now it's pretty easy going to mil-power. With a slight push one enters the AB zone.
