|Thread: VOLANTEX asw 28|
I second Steve's recommendation of the Easyglider as a good starter option. Other cheaper alternatives if you are looking for a motorglider would be one of the Bixlers (there are several variants) or Phoenix 2000, both from Hobbyking.

|Thread: OpenTX not displaying sticks|
I've never used an X-Lite, but can you scroll through different display options using the multi-function joystick (dimpled control, bottom right of your picture near the two black buttons)? There must be multiple options for the display when flying; a quick Google showed me YouTube videos on using that screen for telemetry info...

|Thread: VOLANTEX asw 28|
In my experience it is best to be blunt in this situation to avoid the model going home in a bin bag. Very few beginners will persist with the hobby after that kind of experience!
Andrea, please heed the guidance in the post above from Jason. I would personally go further and say this model is completely unsuitable for a beginner - it will be pretty fast and the long, slender wings (known as high aspect-ratio) mean that it is likely to have stall characteristics that need an experienced pilot to manage. If you try and fly it yourself without any instruction it is almost certain to go home in pieces.
In short get yourself to a club for a go on their trainer and/or find an experienced pilot who can maiden it, trim it out and give you some instruction.

|Thread: Aurora 9x|
Thanks for the compliment - are you feeling alright?
I see where you are coming from re: service and spares, but in the case of the Jumper and Radiomaster they have already reached a critical mass of buyers across the world. That means that even if they disappeared tomorrow someone would step in with replacement gimbals, switches etc (they have been a huge hit with the multirotor community). Yes you'd be fitting them yourself, but if your happy with that I don't see it as a major problem (also their low purchase price does offset this concern quite a bit).
I agree the initial setup of these modules is somewhat fiddly, but if means you can keep using existing RXs from (say) Hitec which would otherwise have to be sold/disposed of that is time well spent. Don't forget too that most people only actually use these modules for 1 or 2 protocols - their previous brand plus whatever they want to use moving forward (I suspect in the vast majority of cases that is Frsky).
I quite like SBUS in the right place and it's hugely popular amongst multirotor pilots, but yes I bus systems do have disadvantages as well as advantages that manufacturers like Futaba like to gloss over. Frsky still makes plenty of non-SBUS RXs though so it's not an issue I worry about. The Powerbox TX though... you'd have to be a very brave person to invest in that. I understand it is built on the old Weatronic system, and we all know what happened to them!.
I understand even Futaba was dismissed in the early days as "cheap tat" - seems ridiculous now hey! They aren't my favourite - I find the programming somewhat illogical - but they have remained where almost all of their competitors from back then have disappeared.
I can only speak for Frsky (not Jumper or Radiomaster), but I haven't seen any real evidence of they QA on the TXs being any better or worse than the "big brands". Switches and gimbals on the cheapest sets will wear out eventually, but are fine on the £100+ models and up; everything else seems pretty solid. Their RF boards are certainly reliable, unlike the cheaper models of Spektrum where I have lost count of the number of board replacements some of my peers have had (DX9 and above seem much better though).
I know there have been known issues with some Frsky receiver models in the past, though I haven't personally experienced any - all my V8, D8 and D16 RXs have run faultlessly since I started with them ~10 years ago. Frsky's biggest negative point is the miss-steps made when EU regulation changes rendered their old protocols illegal (the first EU LBT firmware had a number of issues). They also do seem to periodically try to force obsolescence on their users with changes to their protocols (this has happened recently primarily because they were losing market share to Jumper and Radioamaster), though innovation from the open source community means it's never long before a workaround is identified! They aren't alone in that practise though - Futaba, we're looking at you...
Sadly there's no doubt about that - they said in 2017 they would produce no more new TX models as they cost a lot to develop but were only a tiny proportion of their sales revenue:
Once this generation of products becomes uncompetitive in the marketplace they were always going to be withdrawn, and it seems that point has come. You are right though, it is a shame as the Aurora in particular was always a great set.

Following on from Pete's point above, it's important to understand the reasons why "cheap Chinese" brands like Jumper, Radiomaster and (most obviously) Frsky can punch above their weight against the higher priced big brand names. It's all about what they aren't paying for - marketing, extensive distribution networks and software development. This means their model has far lower costs, so they can invest more in the physical hardware and still hit a low price point.
The lower priced TXs from these manufacturers (Jumper T8/12, Frsky QX7 etc) are still only average in physical quality, but they are on a par with entry level sets from Spek, Futaba etc that cost £50-100 more. The higher priced sets like the Horus X10/12 really high quality, up there with the very best in terms of physicals - Hall effect CNC gimbals, high quality switches etc. This is why the likes of Hitec have pulled out of TXs - they were always a relatively small player and they can't compete with Frsky et al without completely changing their business model. It's a shame but at least you will have options that keep your RXs out of landfill if your existing Hitec Tx does pack up at any point.

They’re discontinued in the US site though, and they completely out of stock at every UK retailer. Hitec TXs are sadly no more.
More info on the Jumper radios (there are several, but all come with the multiprotocol module)...
...and the Radiomaster:
Here is the list of protocols the module can transmit, and a video comparison of the two radios - the Radiomaster is considered the better bet at this point by most people, though it's very close and the differentiating features may not be important to you:

I would suggest you look at the Jumper T16 or Radiomaster TX16S; both utilise the same multiprotocol module which will allow you to run all of the Hitec receivers you already have and others from FrSky, Spektrum or Futaba if you want. They are amazing value too with Hall effect gimbals etc, though some of the physicals are a little low rent as you might expect for the low price. You’ll also have to accept learning OpenTX which may or may not appeal after Hitecs more straightforward but less flexible OS. Alternatively you could plug one of the multiprotocol modules into any TX with a JR slot, though the choice of new partnership TXs with that capability is limited to the ones listed plus those from Frsky.

|Thread: How far do you travel to the nearest decent model shop?|
This thread was brought back from the dead by Mike Etheridge for some reason; the data from the poll is over 5 years old. A lot has happened since then, including C-19 so I wouldn't bother analysing the results too closely!

|Thread: HK Paramotor|
OK, starting to get grumpy now... Ever since maidening my paramotor there have been zero weather windows to fly it again! I immediately refined my setup ready for another go, but the wind hasn't dropped below about 10mph for nearly 2 weeks. Infuriating! Come on summer, get your act together...
|Thread: Motor Braking|
No, it doesn’t make any practical difference where the motor stops on a folding prop. Just make sure the blades are free enough to fold back easily without too much resistance, that is really The only issue you can have with a good quality folder.
|Thread: How Windy is Too Windy|
Agreed - I don't tend to go power flying in >12-15mph, but that is mainly because I would rather be sloping in those conditions
|Thread: The Gov't, CAA, BMFA & UAV legislation thread|
I am not surprised they changed that wording - whoever wrote it probably got a stern telling off! Always write with your target audience in mind...

|Thread: Old posts deleted|
Here is a reasonably digestable definition of what constitutes "Personal data" under GDPR...
"The term ‘personal data’ is the entryway to the application of the General Data Protection Regulation (GDPR). Only if a processing of data concerns personal data, the General Data Protection Regulation applies. The term is defined in Art. 4 (1). Personal data are any information which are related to an identified or identifiable natural person.
The data subjects are identifiable if they can be directly or indirectly identified, especially by reference to an identifier such as a name, an identification number, location data, an online identifier or one of several special characteristics, which expresses the physical, physiological, genetic, mental, commercial, cultural or social identity of these natural persons. In practice, these also include all data which are or can be assigned to a person in any kind of way. For example, the telephone, credit card or personnel number of a person, account data, number plate, appearance, customer number or address are all personal data."
They also have some good material on the Right to be forgotten.
The above aligns with discussions I have had at work with members of our Legal and Privacy teams. I would say that (unless people start posting their names and phone numbers in posts) the only personal information on display is the forum ID, and even that is unlikely to allow identification in the real world. On that basis if any forum should be able to address this problem by stating at signup that no personal information should be posted in usernames or forum posts, and that if you wish to leave forum posts can be anonymised but not deleted unless they are explicitly found to contain personal information. Of course the forum owner must still comply with a request for erasure of any PI associated with the users account that was given at the point of sign-up (name, address, email address, phone number etc) but is not on display to other users.
I can understand why owners may be nervous about saying no to people who want posts deleted. However, there has not been a high volume of cases yet despite the regs going through >2 years ago, so the risks to a forum like this are IMO very small - far more likely are the big cases against major institutions like BA, Marriott etc where big money fines are obtainable. YMMV.

|Thread: Jeti new Tx for 2019|
Blimey, give it a rest Richard. That post was made over 2 years ago (for some reason perttime responded to this thread yesterday after a 2 year gap), and it remains factually accurate. My point was and is that the logic within the Jeti OS is very similar to Multiplex or OpenTX i.e. they fully separate inputs, mixes and outputs and then integrate logical switches for additional functionality. This is in marked contrast to Spektrum, Futaba etc that mostly rely on fixed master/slave mixing labelled by control type (i.e. elevons).
The former approach is far more flexible as you know from your Mpx sets (I also used an Evo back when I was on 35MHz, a great set though the build was somewhat questionable). Indeed the original creators of OpenTX are quite happy to credit the Multiplex P4000 logic as being an inspiration behind their original project to create a fully flexible open source OS. It is a great shame that firmware could not have been updated by Mpx - they could have been in a great position if they had - but it's creator was apparently killed in a car crash and it was insufficiently documented for anyone else to continue his work.
I get that you don't like the more complex setups that some (including me ) often use OpenTX for, and that's fine - your hobby is not my hobby, we are all different. You are welcome to choose and use whatever kit and setups you like, but please afford the rest of us the same courtesy.

The way I understand it, they went for halving the weight. Many prefer a lightweight tranny to a heavyweight one.

|Thread: Fixing bubbles in EPP tape covering|
Lam film is great stuff, but it does take a fair bit of technique to get a good finish as there is no stretch in it. One old school low each alternative is brown paper and diluted PVA; once that is dry cover with tape or film of your choice. Tough as old boots and easily reparable if the worst happens, though probably slightly heavier than lam film or tape.
