FrSky, Spektrum and Other Proprietary RF Protocol Radio Systems in Use In the USA in the Fall of 2021
By Ken Myers

Forward:

     On a trip to the flying field on Saturday, September 18, 2021, I saw Dave Stacer return a Bixler and transmitter to Sean Logan. Dave had set up the transmitter and plane for Sean. The transmitter was a FrSky Taranis X9D that Sean had purchased several years ago. After Dave test flew the plane, there was a bit of talk about radio systems that are available today, in the fall of 2021.

     There was some talk about whether Sean might want to move to a Spektrum radio or remain in the FrSky ecosystem.

     In the following article, I've presented some information about the FrSky and Spektrum ecosystems.

FrSky and Spektrum Information

A Bit of Info Regarding FrSky

     First, the company name, FrSky, is pronounced Free-Sky, per their own documents.

     Dave and I discussed some of the problems with the FrSky ecosystem and OpenTx, while at the field that day. One problem was that the FrSky ecosystem is very complicated at this time, fall 2021. FrSky's most current systems use the ACCESS firmware (protocol?) and OpenTX as the operating system (OS). Before that FrSky used the ACCST firmware, which came after their original firmware.

     If you visit the Aloft Hobbies Transmitter Website page, you are presented with the following information.

     Note that I've used ... when I deleted some of Aloft's wording and put things that I found "interesting" in bold fon.

     "FrSky offers two LCD displays, Large and Small and they have two larger Color displays, one with touch screen. The small displays are in the Xlite and X9 Lite and Q X7 radios, the Large LCD is in the X9D and X9E radios, and the large Color display is in the X10 and X12 radios while the large color touch screen is on the X20 transmitters."
and

     "All of the radios can run on OpenTX except the X20.

     This (OpenTX KM) is a very powerful programming environment. ... The X10 and X12 radios come with a menu driven system called FrOS, ... but if you want the power OpenTX you install it onto the radio! ...

     The X20 transmitters run the new EthOS firmware, a new development excliusive to FrSky. Think of it as an easier to manage OpenTX. (Note that it says firmware, not protocol or OS and exclusive is misspelled. KM)

     All of the FrSky radios also have an open module bay on the back. ...

     FrSky does not include much in the way of instructions, so at Aloft we offer a wonderful professionally written series of manuals. ... We highly recommend these manuals for everyone, new or not."

On Aloft's Receiver Webpage it notes;

     "The FrSky Family breaks down to the Archer, ACCST and vintage forms. Archer's use FrSky current ACCESS protocol (Note that it says protocol not firmware. KM) and is a very robust line of receivers. The ACCST family are a little older and bind in D16 mode while the vintage series will be binding in the very old D8 mode."

     "Besides OpenTX, FrOS, and EthOS there is a newer "fork" of OpenTx called EdgeTx. There is another open source OS known as erskyTx, which can also be used on FrSky transmitters.

     More information regarding erskyTx can be found here.

     A note on the link from above says, "Development continues in both erskyTx and openTx, with ideas and code passed between them." The date of the post was May 6, 2021.

     FrSky, the hardware manufacturer, is not OpenTX, the operating system, and OpenTX is not FrSky but they are related and associated with each other. They have a symbiotic relationship. That means that a change in either one of those affects the other.

     FrOS is a "fork" of OpenTX created by FrSky. OpenTx and EdgeTx are open source software operating systems created and shared by dedicated individuals worldwide.

     We also discussed some of the problems with OpenTx.

     A look at the OpenTX download page demonstrates both the advantages and disadvantages with the OpenTx OS.

     TodayÕs date is 10/31/21 and it is 31 days since the latest update of OpenTX to a newer version of 2.3.14.

The following listing covers the most recent 521 days with 8 updates visible and one NOT visible on the download page.

OpenTX 2.3.14 (2021-10-01)
Emergency fix of Companion for Windows

OpenTX 2.3.14Ê(2021-07-23) lasted 69 days

OpenTX 2.3.13Ê(2021-06-24) lasted 29 days

OpenTX 2.3.12Ê(2021-06-14) lasted 10 days

OpenTX 2.3.11Ê(2021-01-08) lasted 157 days (most stable version)

OpenTX 2.3.10Ê(2020-10-06) lasted 94 days

OpenTX 2.3.9Ê(2020-06-14) lasted 114 days
Note: "This version fixes two issues introduced in 2.3.8"

OpenTX 2.3.8Ê(2020-06-13) lasted 1 day
Note: "CRITICAL ISSUE download of this version disabled"
Note: A lot of fixes with a lot of stuff on various Tx and in Companion!

OpenTX 2.3.7Ê(2020-03-28) lasted 67 days
Note: "New since 2.3.6. Replaced the Same day
COLORLCD
remove FrSky OTA lastest change as it crashes SD Manager"

OpenTX 2.3.6Ê(2020-03-28) (lasted less than one day)

     All of these were posted as stable versions on the OpenTX download page, but there were three critical updates during the time period!

     2.3.6 lasted less than one day before 2.3.7 was released. 2.3.8 lasted 1 day before being updated to 2.3.9. 2.3.12 lasted 10 days before being updated to 2.3.13 and even then 2.3.13 only lasted less than a month, 29 days, the "original" 2.3.14 lasted 69 days before being updated to the current, newer version of 2.3.14, which has been current for the last 31 days.

Confused Yet?

     "The OpenTx project page can also add more confusion when trying to learn and use OpenTx.

     I'd been looking at a FrSky Taranis X9 Lite S and wanted to know if it was a supported radio.

     When I clicked on the Radios tab on the OpenTx homepage on September 25, 2021, the Taranis X9 Lite S was not there but I knew that I'd seen it in the OpenTx Companion list of supported radios.

     I then found that radio listed here. (Look in the middle of the shown list.)
July 27, 2020 (Please Note the Date of the posted video)

     I thought that it was odd not to have the S-version listed on the OpenTx Radios tab page, since it was in the list of supported radios in Companion on July 27, 2020, as shown above. The S version was released in August of 2019 and the original, without the S appended, in May of 2019.

     You'd think that FrSky hardware and OpenTX are not the way to go and that "biting the bullet" and purchasing the much more expensive Spektrum brand, where the hardware and software are "designed in house" would be the way to go, and it just might be but...

A Bit of Information Regarding Spektrum

     Spektrum has their own ecosystem. For the most part, Spektrum does a better job of keeping legacy receivers compatible, compared to FrSky. You can also go to almost any hobby shop in the US and purchase Spektrum transmitters and receivers, along with bind and fly (BNF) planes that have Spektrum receivers in them. The BNF planes are ready to bind to a Spektrum transmitter and then start flying them.

     If you look for the Spektrum brand of transmitters, DX#, NX# and iX12 or iX20 in the Radios section of RC Groups, you'll see posts noting some of the problems that users are having, or had, with their past and even newer Spektrum equipment.

     The NX line of Spektrum transmitters, their newest iteration, has had several firmware updates, to fix bugs in the OS, since being launched in October of 2020.

     While in the Radios section of RC Groups, you can also look for information regarding OpenTX and FrSky equipment.

     In the Vendors section of RC Groups there is also a dedicated thread for FrSky.

A Word about Programming, Firmware Updates and the Like

     When it comes to programming, both Spektrum and OpenTX have "learning curves". For someone who's never used a RC transmitter, programming beyond a basic 3-/4-channel plane can be perceived as difficult because the beginner has no idea how some of the options, past the basic three of four functions, actually work on a model airplanes.

     Over time, both of these operating systems have added more and more features and abilities to their operating systems. FrSky and Spektrum have both "upgraded" their hardware as well. Both are, arguably, very reliable in the air, where it counts.

     Spektrum has, by far, a much larger following in the RC model airplane community, so help with questions and general setup help can usually be found at almost any RC model flying field as well as online in forums and from Horizon Hobby.

     FrSky and OpenTX have a huge presence/following on YouTube, so help can be found almost anytime of day or night on the Internet.

     Both systems require a fairly decent understanding of computers and/or cell phones to update firmware and save files for specific settings and models. Those are advanced skills for sure.

     A recent YouTube video exists where a young man shares his opinions regarding Spektrum and FrSky with OpenTx. He based the information, that he presents, in this video after using both Spektrum and FrSky equipment using OpenTX for several years.

     I have presented MY comments regarding this video. MY comments should provide some background before viewing he video.

My comments regarding this video:

1. At 0.40 Tim holds up a Spektrum DX6i, that he has obviously painted blue, and notes that it was the first Spektrum transmitter that he purchased. The early DX6i, circa 2007 - 2009 had two physical flaws. The trim switches and scroll wheel stopped working after a short period of use. A cottage industry arose to provide a fix for this quality control problem. A gentleman made, and supplied, new trim switches and a scroll wheels specifically for the DX6i. The earliest DX6i transmitters used DSM2 where only 2 channels of the 2.4GHz spectrum were used. That protocol was change on the DX6i to DSMX in about 2009.

2. At 4:31 he talks about who has the "better" 2.4GHz radio link. What he says here is very much an opinion and he does not present any facts to back up his statements.

3. At 5:38 he notes that he had a problem with one Spektrum receiver and goes on to note that, because of that one problematic receiver, he now uses Lemon receivers with his Spektrum transmitters for his outdoor models. It is not unusual for any brand of receiver to have a problem. Sometimes the problem might affect a whole line of receivers, but sometimes it is just that one single receiver. That's why we do a range check.

4. At 8:40 he discusses stick tension. Stick tension is an extremely personal preference. He likes his very loose. I like my rudder stick to have quite a bit of tension compared to the throttle stick so that it wonÕt move the rudder accidentally when I'm moving the throttle. I also like a ratchet sound and feel on the throttle, while others prefer no sound and a smooth sliding motion. I also like the elevator stick to have more tension than the aileron stick so that it makes it a bit more difficult to add unwanted elevator commands when using the aileron stick.

     Overall it is a pretty good video and with mostly spot on information. It was posted on May 16, 2021.

Comparing a Simple Airplanes Setup on Both Radios

     The following video, although older, shows one way to set up a basic airplane on the FrSky Taranis line of radios. It also has a brief description of how the Taranis differs from a Spektrum DX7 and actually all other proprietary menu driven programming systems by other manufacturers. This is also how to do it on the Jumper T12 and RadioMaster TX12.

     The next video demonstrates another way to set up a basic airplane using transmitters that can use OpenTx and that have large color screens such as the FrSky Horus line, Jumper T16 and T18, Radio King TX18 series, Eachine TX16S and the various versions of the RadioMaster TX16. Instead of using pages as the smaller screens do for each selection, the larger screens present tabs across the top. Other than that, the programming is exactly the same for both screen types.

     The following video is long as John Hopke was doing a live class when he made it. It covers a lot more info and his demo plane is pretty neat. New Spektrum receivers also use a bind button on the receiver not the old bind plug method, as he mentioned in the video.

     He demonstrates two ways to do a throttle cut. I recommend you skip through the second way to do the throttle cut and start at again at 32:32, where he starts discussing dual rates. Watching the video can be ended at 36:30 if you wish. There is a bit of programming involved here, more so than with a Spektrum. He also has a video that fully covers programming dual rates and exponential, here. The following video is more info than most need to know at this time.

Other Radio Systems for RC Airplanes

     I concentrated on the previous two radio systems, as they are currently available and somewhat in competition.

     There are also other systems that are currently available that will certainly work with RC airplanes.

A Look At Some Other Brands

     John Salt does a quick review on many of the RC systems that can be used in airplanes, as well as helicopters. He left two brands in his updated article that are gone now. Hitec and JR are no longer available. I searched a lot for Graupner HoTT, and cannot find a dealer with much of this line in stock in the USA, especially at the lower price points.

     The USA warehouse of Hobby King has several lines of stick transmitters available.

     WFLY is also available in the USA at the present time. They tout themselves as a long time Chinese producer.

     Their line is sold on Amazon. Some of their line, transmitter and receiver combos, appear to be available here in the US, but most of their receivers are not.

More on OpenTx Programming for Those Interested

     Lee Schofield (Painless360), has a very good playlist on YouTube for the older Taranis X9 style transmitters. The videos are older, May 2015ish, and the information should match Sean's Tx quite well, I believe.

     John Hopke (RC Video Reviews) has four relevant playlists for using OpenTX on YouTube. The playlists are much more current regarding the "how-tos" of OpenTx. He uses a RadioMaster TX16 transmitter for his lessons. That Tx has the large color screen that shows tabs instead of the pages shown on Sean's transmitter, but the programming is the same.

OpenTX Classes

     Much of the information on YouTube, regarding OpenTX and FrSky, is "drone" oriented. I like both of the previously mentioned guys as they are not just "drone" fliers.

     Josh Bardwell also has a lot of good info on both FrSky and OpenTX scattered through his videos on YouTube, but he is a "drone" guy and is actually the columnist for drones in Model Aviation at this time.

The August and September EFO Flying Meetings


Denny (foreground) and Pete (background) flying on this very grey day

     Saturday, August 7, 2021 was a very overcast day, but it did not rain.

     While the attendance was a little low, we all had a great time.

     Ken, Dave and Denny were able to help a new flier with his plane, and Ken got the chance to actually hold and fly a RadioLink A10ii transmitter.

     Denny Sumner spent a lot of time helping the newcomer. Thanks for your expertise Denny!

     Pete Foss flew his Flex Innovations FV-31 CYPHER VTOL SUPER PNP.

     It flies and behaves very well in the air. It uses a flight controller to control the flight modes and the controller works very well. Thanks for sharing Pete!


Dave Stacer assists the new flyer with his plane and radio system

     On Saturday, September 4, 2021 the sky started off a bit dark, but it grew a bit brighter as the day went on. he attendance was quite good. It finally turned out to be a great day for our monthly get together.

     The guys gathered and chatted on the cool morning.


Dave Stacer, Jim Young, Denny Sumner and Paul Sockow have a chat

     Around lunchtime, the sky brightened. Lynn Morgan's pattern plane is shown in the front, center of the photo. Lynn flies in pattern contests throughout the Midwest.

     Keith is shown taxiing out for a takeoff. His old Multiplex Cockpit has been updated with a FrSky internal module.

     The last photo shows what a beautiful day it turned out to be as the guys chat away under one of Midwest's sunshades and Jim Young flies in the background.

John Hoover Inducted Into the AMA Hall of Fame
From Joe Hass via email

     On Sunday, September 19, 2021 it was my pleasure to present John Hoover with his plaque and paperwork inducting him in to the Model Aviation Hall of Fame.

     Once I confirmed John's induction, I worked with John's wife Tracie and family for a "surprise" event at his hobby shop (Flightline Hobby in Lake Orion, MI). The local clubs that John supports were on board. More on the "surprise" later.

     I have a very specific program for HOF inductees. The announcement letter is framed with a generous mat so that those attending can sign and add their personal messages. There is a specially decorated cake. In this case we also had sandwiches, snacks and beverages. I also create a presentation binder with the nomination and other related memorabilia.

     As she has done so many times in the past Erin Dobbs, from AMA headquarters, provided that unfolded announcement letter as well as the supporting documents and plaque in record time. Prior to that Erin helped with a last minute addition to the nomination to get it in before the deadline.

     Coincidently, I had submitted an article about John to Jennifer Alderman for the VIEWFINDER. While the article documented John's many contributions it did not include anything about the HOF. I submitted an amended article with the HOF announcement and Jennifer used that in the October issue of MA. She also got me a PDF of the article so I could have it printed and framed for John before the presentation.

     With a series of less than truthful stories I got John to agree to use the front of his store for a "surprise" presentation. Tracie confirmed that John had no idea what was going on.

     Three days before the "surprise" I stopped in the store for some supplies. Tracie happened to be there and whispered to me "John knows". With the publication of the digital version of MA the world knew of John's induction. The first congratulatory communication to John came from France! ÊThe cat was out of the bag. While we didn't have quite the "surprise" we were planning we had a great time thanks to the work of Erin and Jennifer.

(See Model Aviation, October 2021, Viewfinder, p. 22 to learn more about John. KM)
