Graham Bowers Posted August 17, 2023 Share Posted August 17, 2023 Whilst I wait patiently for the delivery of my Jeti I've spent some time reading the instructions that I've downloaded and watching some of Harry's excellent videos. I'm very much a visual learner and like to see structure and the big picture. When I was learning the Multiplex Profi 4000 some time ago, I found the attached flowchart very helpful. Has anybody found anything similar for Jeti, please? 4k_flowchart_v1.pdf Quote Link to comment Share on other sites More sharing options...
PeterF Posted August 17, 2023 Share Posted August 17, 2023 (edited) I have not seen anything like this. With Jeti having a niche market I watch the RC Groups Jeti thread as that has some experts who contribute including Harry C. There is also a German sire but translation is required. https://www.rcgroups.com/forums/showthread.php?1693301 Edited August 17, 2023 by PeterF Quote Link to comment Share on other sites More sharing options...

I'll probably make my own - a sort of mind map. I was alerted to Harry by the vendor, John. I've been chomping my way through his excellent material with the hope of hitting the ground running when it arrives. I'll take a look at the RCG thread too.

Trevor Posted August 17, 2023 Share Posted August 17, 2023 Let us know how you get on - I too looked for something similar having come to Jeti from my Multiplex 3030. However, the number of options in each menu is so much larger with the Jeti system, not being limited by the three line screen of my 3030, that I think any attempt to chart it would be somewhat unwieldy. It might be possible with a series of linked web pages rather than a traditional flow chart though? Like all modern radios, I do agree that you do need to build up some sort of mental model of how the programming works in order to become fluent with it - at least in those areas that you want to use. I'd wait until you get the transmitter, then go through a few of Harry's videos again, with your transmitter in front of you, and I'm sure you'll soon get your head in tune with the designer's way of thinking. 1 Quote Link to comment Share on other sites More sharing options...
John Lee Posted August 17, 2023 Share Posted August 17, 2023 I moved to Jeti before Harry started his excellent channel. I quickly became comfortable with all the basics but for some of the more obscure stuff I found Jeti USA's videos pretty useful at the time. They tend to be a bit shorter than Harry's & cover specific issues, but you may find them a useful supplement. https://www.espritmodel.com/jeti-video.aspx Quote Link to comment Share on other sites More sharing options...
Dickw Posted August 17, 2023 Share Posted August 17, 2023 Graham Have you had a look at 'Jeti Studio' yet? https://www.jetimodel.com/support/ Studio includes an emulator in which you can play with setting up models. OK, it is for the DC/DS 24 so will have all the unlocked functions that you don't have, but the basic functionality will be the same as your 12 so you can get used to it and make any mistakes there and not on the real thing. I often use it for experiments. The only flow chart I recall from the early days of the Jeti Tx is attached - very basic but it is a starting point.

Bruce Collinson Posted August 17, 2023 Share Posted August 17, 2023 There’s some useful YouTube’s from the Australian agent too (I did NOT put that superfluous apostrophe in there!) which are similar to the US ones and I have found very helpful for some relatively basic but nevertheless well hidden functions. More succinct than Harry C’s. BTC 1 Quote Link to comment Share on other sites More sharing options...

I'll see how I go then Trevor. Maybe a mind map is the sort of thing to shoot for. As you say, it's to build up a mental picture of the functionality. For me, it's to both help with learning fluency, and also to have a source of reference on the wall for the less well used functions. On one piece of paper.

John mentioned Jeti Studio and I did download and install it on this computer, however hadn't got as far as discovering the emulator - which I now have. It looks dead handy.

MattyB Posted August 17, 2023 Share Posted August 17, 2023 (edited) Looking at that, it maps very closely to Mike Shellim's famous flow diagram for OpenTX, which also applies to EdgeTX too... That is probably too simple to be useful for what you want to do for your new Jeti @Graham Bowers, but maybe mapping out something like this one for erSKY TX is what you need - jsut posting in case it gives you ideas...

I am sure there was some cross pollination of ideas 😀 It's well known that the original team behind the 9x open-source firmwares were "deeply inspired" by Multiplex's approach, and whilst there is nothing to indicate they copied any of the code, the concepts are writ large throughout the firmware. These firmwares were the foundation for erSkyTX/OpenTX/EdgeTX, and predate Jeti's TXs by some time - they've been around since the early 2010s at least, probably longer. @Mike Blandfordis the man who will know the dates for sure!

The penny hadn't dropped that Jeti were so late to the party to be honest. Can't blame the open source competition for benchmarking against Multiplex functionality. I'm not sure where the boundaries of IP lie and have no view, one way or other on IP matters. It's a shame Multiplex failed to build on what they already knew when they developed the new Profi, but sadly that's all water under the bridge ;-( Quote Link to comment Share on other sites More sharing options...

I can’t remember whether the source code was lost or simply unintelligible to anyone else, but either way, it was a dead end for them, so much so that when they went to develop its successor they started from the Royal Evo firmware instead. If they had built some nice hardware for OpenTX at that (pre-Taranis) point they may have been in a really good position in the radio market now rather than a bit per player. 1 Quote Link to comment Share on other sites More sharing options...

Well I didn't know that, what a tragedy for him and them. Thanks for explaining. A leap to open source hardware was probably a leap too far as I get the impression MPX were / are very conservative. Witness how slow they were to adopt 2.4 GHz. However allowing such important stuff to become so vulnerable isn't exactly best business practice - although I see the world through the lens of a global corporate employee, retired. I do know that best practice is not as wide spread as one may hope. But as before, all water under the bridge now. 1 Quote Link to comment Share on other sites More sharing options...

It's the old story with software. A brilliant coder who fails to document what they do either because they can't be bothered or to make themselves indispensable! Either way, it's a disaster for those who have to pick up the pieces. 2 Quote Link to comment Share on other sites More sharing options...

I mostly agree Peter. However in my opinion, it's a management failure if a brilliant coder is allowed to release undocumented code. 1 Quote Link to comment Share on other sites More sharing options...
Don Fry Posted August 18, 2023 Share Posted August 18, 2023 Managers seem to have skills, unrelated to the task. I first noticed this as a 15 year old, asked by my headmaster, what I wanted to do in life. He was a truly fine teacher of Physics, an upright, if puritan character, who had a odd, but very entertaining sense of humour, who I liked, feared, and respected. A headmaster, defined. Careers advisor, nil point. Quote Link to comment Share on other sites More sharing options...

Throughout my career I encountered managers of hugely varying levels of management skill. In my opinion, it's all down to senior leadership.
