Well I am an EE so I will give my 2 cents worth. I have been flying R/C and an engineer for 40 years and I have a lot of transmitters and built a few of them myself. I have a bit of knowledge on gimbals. I still think the best sticks ever made were the Proline metal open gimbals back in the 70's. I was waiting to get a Spektrum iX20 and it kept getting pushed back, so I finally decided to check out the OpenTX as it appeals to my DIY sense of adventure. Of course I researched the heck out of it and got a FrSky Horus X10S Express and the Radiomaster TX16S. I looked at both the Jumper T18 (all 3 versions) and the Radiomaster. I pulled the data sheets on the pots and the hall effect sensors and came to the same conclusions that you did. Still not sure why the Alps are so great other than their good rep. The best pots I've used in my career are the Clarostat conductive plastic pots due to the fact that they don't build up sludge like carbon pots do (which causes static in audio use). After I looked at the linearity specs on the hall effect sensor, I realized it was a twofer, quite a bit better than a traditional pot and no physical components rubbing together and degrading. As long as you can keep the hall effect sensors from strongish stray magnetic fields they should work great. The Jumper seemed to be a no starter since they couldn't figure out how to put an off the shelf charging circuit in the radio. (great video on your add on). Really enjoying your series on OpenTX, might have some questions for you if I can't figure some things out. Keep up the good work.

I think I have an observation about linearity: it is true that the hall sensor has no mechanical stress (apart from the temperature whose impact we can not evaluate) so having a linearity index lower than the potentiometer should return a more qualitative signal, but it is also true that this result is necessarily influenced by the linearity of the magnetic flux emitted by the magnet connected to the stick. Unfortunately there are no data on this component but it is quite certain that the flux cannot be perfectly homogeneous because of the microscopic imperfections that inevitably has a magnet so small (both dimensional and density of the material). The potentiometer, on the other hand, can only suffer interference from the possible inaccuracy of the bearings. But both gimbal have bearings so this data is irrelevant to compare them. To me this implies that the gimbal based on this super robust potentiometer component is more likely to have superior linearity.

Great breakdown and busting the hype with data. Feel is highly subjective, and no human hand will spot the 3% or 1% accuracy level with those gimbals. The reality is however there is a lot of consumer choice today and frankly we're all rather spoilt with choices for radio options these days. I think you're on the money John with your opinions regarding OpenTX radios in any case - go the TX16S or get the T18 Lite it all makes sense now you've busted the hype and quantified the facts from fiction and you did it without saying "oh I feel this is better" haha.

Yeah, I watch video after video with the speaker always interpreting what feels better or worse. Assuming bearings all the way around and no inherent mechanical flaw, I believe the only real differentiator is spring tension and/or spring weight. You're right though: We have a lot of very good options.

A mechanical RDC90 Sensor is a complete unit. A hall effect sensor is only one part of the sensor, it needs the part generating the field to measure, the magnet inside the moving part. And here we go, to archive perfect linearity, it needs so to be sure that the magnet is moving in a perfect way to the sensor and back. Let's face it, who will really feel 3% non-linearity? As long as the center remains center, it doesnt matter if at 50% stick throw you output 1500uS, 1505uS or 1515uS. Nobody will feel that. And about long life - both my old radios, a 15 year old Multiplex, or the X9D with poti Gimbals, they both work still fine. I also prefer Hall Effect, because it feels better in the brain. But honestly I am not sure if I would feel the difference in a blind test.

Wonderful information. Thank you!

I upgraded from an older Futaba T8UA (on a 2.4 Gig module) to a Taranis X9D plus SE with hall gimbals a couple of years ago. (Before Radiomaster T16S came on market) Sensitivity of the sticks was amazingly apparent and did take some getting used to, mostly due to geometry and lighter tension of the shorter sticks. My flying has improved and I'm glad I spent the extra $ for the premium M9 gimbals. If buying today, I'd go for the T16S due to quality gimbals, desirable features and an even better price. Yes, so many choices now.

The Jumper Lite and TX16s are both good radios. You can't go wrong with either one. I haven't done my side-by-side video yet, so I can't say yet which one is better. If your primary motivation is getting the radio with the best gimbals, that decision for me is the TX16s. But we know there's more to a radio than the gimbals right?

I'm an EE and I have a parts set around for like a decade now to build my own radio mainly because I want a 3-stick and my own protocol. Not sure if I'll ever actually get around to it since it's so much work but the joystick I chose was a potentiometer, not hall-effect. There are a few reasons some of which involve integration and flexibility for future modifications the system. But the reason you might be interested in is that I kinda don't entirely trust the accuracy or rejection of hall effect sensors. A hall effect sensor has a lot more distinct bits and pieces to implement and align and if I was making a gimbal myself I certainly wouldn't trust myself to. Now if you buy a gimbal and assume the manufacturer has jigs and has perfectly taken care of all that there is still the issue of stray fields and such. Though I've never directly worked with and messed around with a position hall-effect sensor...yet (I have some for a vane AOA sensor which I also have not gotten around to building yet, if ever), but I have experience with other hall sensors. Namely, clamp on DC current probes which use hall sensors. They are supposed to have a closed loop and reject extraneous fields but I have picked up surprisingly strong fields from rather far away. The probes ran from $1k all the way up to $5k and would pick up 2-3mA of current from energized transformers (30lbs-40lbs maybe?) basically running open circuit at 0% capacity from a few yards away. The probe was running at 100mV/A for a range of 5A which now that I calculate it works out to be just 0.06%. Or I'm mis-remembering and it was actually 20-30mA which would make it a whopping 0.6%. Not to say that hall-effect was a deal breaker by any means but I do distinctly remember being uncomfortable at what I saw I have worked with magnetic ring encoders on motors and generators where I frequently turned the shaft by hand for positioning purposes and those seemed rock solid. These were two piece encoders with a sensor and a magnetic ring 4" in diameter. I could change the resolution and if I recall, there was an interpolated resolution of 65,536 steps over that circumference but I almost never used it that way. I think the resolution I used was a lot lower at 1024 or 2048 steps. The hall effect sensor on an RC gimbal would be cramming that many steps into something much smaller circumference, if it even used a ring magnet which I'm 99.9% sure it wouldn't. It would be a single diametrically polarized magnet placed in front of the sensor. Either one sensor-magnet pair for each axis where the magnet face rotates in front of the sensor, or a single magnet at the bottom end of the stick that swings above the face of the sensor like a pendulum in both the X and Y-axis (and can allow for a convenient Z-axis if the stick is allowed to rotate about its axis to rotate the magnet at its end along with it). Obviously more finicky setup than the magnetic ring which I found rock-solid which was basically arunning a long, circular graduated magnetic track in front of a sensor. Sure there's calibration and all...but man, I just don't trust it! A magnet with stray magnetic flux lines moving all which way and that above a sensor.

I'll just contrast your thoughts with this one: I've been flying hall effect sensors for the last 4 years. I've tried firmware/rf protocol measurements to 12bits of accuracy. I've learned that unless you are a space alien, one of the top shelf RC pilots in the world, or fly with sticks the size of broom handles, you will not notice the difference between 10b and 12b. Likewise, unless your hall effect sensors are severely impacted by drift you will probably will never be able to fly in such a manner that hall sensor negatives are felt in any material way. I fly in pretty extreme environmental conditions. 45 degrees F on the low end, 100 on the high end with up to 98% humidity. I have yet to find a situation in my flying where I said to myself, "these hall gimbals have to go". If I could maintain straight and level flight within 1' for three full patterns---MAYBE. Just offering the practical/hands on perspective here.

I was editing my comment up until only a few minutes ago but it says you actually responded 30 min prior so there may be more I wrote that you never got a chance to see. I do like my big 3" long sticks lol. I guess that's comparable to the 4" diameter magnetic ring I was working with and at 1024 I was able to get between steps...but only just. Then again that was 360 degrees and gimbals are only 80 degrees or so. Probably wouldn't come into play in any dynamic flight situtation. I wouldn't ever use pots like the RDC90 on any gimbal I made myself. I'd be using the large bearing supported shafted pots just like the ones I bought to make the my transmitter with.

In all honesty i have Spektrum dx9 dx6 dx6i jumper t16 pro w/hall effect t18 pro rdc90 I can tell a big difference in sensitivity from hall to rdc gimbals but in all reality your correct all the same for most part...

@@RCVideoReviews Yep, I came here while shopping for a T20. While I mostly agree with your conclusion, , I think you missed a few facts. There can be a difference in "feel" because potentiometers are not frictionless, some people actually like that dampened feel. Linearity isnt a measure of accuracy and comparing accuracy from datasheets would be impossible, unless you take in to account the "gearing". non linearity itself, assuming it is constant, should be trivial to account for in firmware. Lastly, hal effect sensors have issues with temperature variation, potentiometers are nearly immune from temperature drift. So if you use your radio indoor and outdoor in winter, you may not like your hal effect sensors that much. Oh, and one more thing. having springs and bearings also doesnt mean they are the same. Some gimbals flex far more than others. Nothing to do with the sensor of course, but a CNC-ed metal gimbal will not flex nearly as much as a plastic one. Dont think that warrants the cost, but thats for everyone to decide.

For the leaf spring I polished with Mothers metal polish using a dremel on a Spektrum DX8G2 and Futaba 14sg with noticeable improvements on the smoothness.

I have used many different radios from Spektrum, Futaba to Frysky and now have Jumper t18 with hall. I am picky about spring tension feel which can be fixed by adjusting or getting heavy duty springs for Futaba. I fly RC Helis, so precision is more important, I like higher tension. The other part of the feel is the left stick( collective) tensioner. I have noticed this varies from brand to brand and is subjective for smoothness based on the quality of the leafspring. I haven't noticed any difference between pot gimbals and Hall effects. The Hall effect you specs said 1000 hrs test. If you were to use your radio 4 hrs a week. That is like 5 years to get to 1000 hrs.

The T16 Hall Sensor gimbals are these with the hall sensors. If you want the tilting sticks, get those.

Add in the fact that there are discrepancies in manufacturing. One of my TX16S gimbals was slightly off center. They just don’t feel as good as my X9D so I sold it and went back. Everyone will have their own preference as you say.

Jumper's marketing department obviously thought that by mentioning the type of pots they were using (RDC90) it would make their gimbals sound fancier, and it seems to have worked, but they are still mechanical components, so they will wear out, and deteriorate over time, requiring more and more regular stick calibration to be carried out as well.

None of this really matters much to me. These radios are all pretty much disposable anyways. A newer, better version will be out in less than 2 years, then its upgrade time again. I don't see wearing out either gimbal types in that short of a time? After a year, just finally received "upgraded ribbon cables" last week for my unusable Jumper T16 & just yesterday learned about some with the wrong STM32 chip? Jumper really screwed us on the T16 & continue the tradition with the T18.....Meanwhile, the Rose Gold Radiomaster T16S should be here Monday. I will never purchase another Jumper product again, unless they pull a rabbit from their ass. Still using the Taranis as my DD.... But what do I know?? Thanks for the informative content..

Hard to argue--I think lots of other things will go before the gimbal sensor. Enjoy your new TX16s. I've grown quite fond of mine.

They sell 2 versions that say hall sensor the others the rdc90 so they have to be different

Ihave a TX16s and a Jumper T16. TX16s WINS hands down! If you are interested in a great TX16s Case mod let me know.

If that's the answer they do a damn fine job of hiding it from everybody. What is the resolution of the RDC90? Is it meaningful to any non robot pilot? Does the software take advantage of it?

@@RCVideoReviews Just a hunch : hall= stable performance that lasts a century. RDC: higher res but prone to parasites ?

I paid 149 for the standard T18 but probably will never use r9

Well, you've got it if you want it, but I really believe the T18 lite is the one to get if you want a Jumper.

RadioMaster T-16s or Jumper T-18 lite. If I were to buy one, it would be RadioMaster. I won a T-18 lite, sooo...... AirHammer out!!

I just posted my T18 v TX16s video. They're both really good radios in the final analysis. I'd be thrilled with either one.
