Cougar Throttle Hall Effect Potentiometer - Cubpilot Reincarnated!
-
Perhaps I will do some inflight refuelling training this weekend as see how I get on.
-
I was thinking about picking up some of those BI 6127 Hall sensors for quite a while, as they’re the ones that Sokol1 likes to use. The main holdup was figuring out how I was going to get a metal mounting bracket and a servo arm to mount it to the throttle, and I think you’ve just given me some valuable clues there. Just gotta find some US suppliers instead.
They’re not just something I need for the Cougar throttle, but also this A-10A throttle conversion project I haven’t finished for a few years.
As for the throttle mods, I had a set of UTM bushings once in my first Cougar; that was sold off a long time ago, only for me to go acquire another one after some withdrawal. Alas, I haven’t found another set of UTM bushings for sale; no tape needed, those things did the job perfectly regarding stiction elimination while keeping the whole thing smooth.
The problem is that nobody other than Ian Johnston can be bothered to make them, and as such, they’ve been out of production like the U2-NXT. For a simple bit of precision machined metal, they’re sure not easy to come by.
That said, I could give the tape a shot, something that should eliminate the “stiction” while adding a bit of damping so it doesn’t feel like I’m moving a wet noodle past the static friction point.

I modded my throttle in a similar way to Scubapics . Rather than mounting a link ball on the throttle shaft I took the output shaft from a dead rc servo removed the gear and machined it to the same size and shape as the original pot shaft. With the tqs upsidedown with the handle at or very near the middle of it’s travel,I inserted the modded servo shaft into the original hole formerly occupied by the pot. Installed a 1" long servo arm in a vertical position. The whole affair fits neatly between the throttle shaft and the original pot mount. Install an identical servo arm on the hall sensor. Link balls mount on both arms at the 3/4" holes. Used a timed out linkage from my rc heli to connect.
I’ll try and get some pics . It actually turned out better than it sounds and I use 99.9% of the sensor’s travel split between max and min throttleDave

Please do post the pics man. I know it’s a PITA to do that, but as good as your description is, it’s still open to reader’s interpretation. Thanks man.

Yeah about that. Sorry for the crappy cell phone pics
I used a Novotechnic RSC 2821-110-241-101 sensor ,one of a handful that I “harvested” from a dead case packing machine. A little large but it does fit and works well. Natively 5vdc supply so no issues with the cougar electrics. In the Foxy axis viewer app throttle is smooth as butter,in the pit I can adjust power by increments of 1lb if I am gentle
To set the position of the sensor bracket I installed the linkage, set both the throttle and the sensor to their mid points and used JB Weld to attach the sensor bracket to the TQS base.T fine tune the position I rotate the sensor in it’s bracket so the zero position of the sensor and the throttle coincide

I know this is an old thread. I have just retired my 15 or more year old Cougar and purchased a Warthog. I have always wanted to do the Hall Effect upgrade but didn’t want to in any way alter the original product. I realize after looking at your images I just might be able to pull it off without chopping it up.

and thats the beauty of this mod

Compared with the Vipergear sensor, that looks like a whole lot of work.
-
Best part of this mod is it didn’t cost me a dime. I also didn’t want to alter in any irreversible way. So now my throttle has the same precision as my FSSB modded stick, and I have the original gimbals as spare parts jus in case. As for the work, a little fiddly, but worth it.

So will this mod to a Cougar throttle be compatible with the TUSBA? My stock pot is a little spikey after 15 years, but I love the newfound TUSBA functionality.

I don’t see why not. If the TUSBA works with a standard Cougar throttle, it should work with this. Have you asked the guys at TUSBA?

I read that Cubpilot Ernie is an obituary, that was a sad news since I corresponded with him. Anyone here know where we can order a microstick?

I use TUSBA R1 with VIPERGEAR hall sensor TQS mod combined with warthog stick and it works like a charm. Easy installation and high enough precision.
-
This only also seems really nifty

where can I find it and does it work for the F-16 HOTAS Cougar Throttle?

Yes it is compatible. I use cougar throttle with VIPERGEAR hall sensor connected via TUSBA r1 to a usb port and a warthog stick. -
thanks for the info., but how come the A-10 flight stick looks exactly like the F-16? I thought the thunderbolt is a very older plane
-
Because the entire A-10C fleet underwent an Precision Engagment upgrade from 2005-2011.
New sensors, SATCOM, IFFCC, all-weather capability, ECM, smart bombing targeting… along with the F-16/F-15 HOTAS mix. Aircraft receiving this upgrade were redesignated A-10C. -
yes I can see pictures of it on the net now, pretty successful flight stcik
