Just to praise the response I recently had from Richard at T9. I needed a new rotary encoder/push switch for a Horus X10. It is a second one that I got as a buddy box. ( I knew the state of it when I got it, I just thought I could live with it) While the push switch still worked there was no "click" which I decided I could not actually live with. They were not listed on the website so I contacted Richard to see if he could help. The outcome, only a week later, is that he now stocks the necessary part, and they are listed on the website. I have replaced the broken part and my transmitter is now 100% functional again. The price is very reasonable and they are an exact replacement. There are similar looking parts available on ebay which will fit the board, but the shaft length is different, and the encoding switching is different, so they are not suitable. For anyone else with a similar problem the only caution I would give is that you need a good level of soldering skills, or know someone who does. The encoder is soldered directly into the board and is not easy to remove. Cutting the legs and then removing the stubs individually from the board is probably the best way. The holes then need careful clearing of solder to allow the fitting of the new part. I am a professional electronics engineer so it was no problem for me.It still took half an hour.

PM now sent, thanks

Sportstar by Simon Delaney I'm looking at building this model, originally Traplet plan 2972. Does anyone have a copy of the original article that they could scan for me please? It's not essential that I have it, as I have the plan and it looks pretty straightforward, it would just be nice to see what Simon originally said about it. It is odd as I can find what I think would be the same article in one of the American magazines, but there is only half of the article available.

Posted by Gary Murphy 1 on 16/12/2019 18:22:37: Bit late now but TJD is my local shop (16 miles) and I was phoning thurs/fri to see if they had something in stock. No answer for 2 days, very unusual. took a chance and went to shop today. There were really busy with customers and loads of deliveries to unpack also heard a staff member talking about the amount of parcels to go out. Just really busy,good to see the business is doing well still. You are lucky. I don't have a local shop anymore. The two nearest to me both closed relatively recently. The nearest now is about 60 miles away. When I finally got in touch I had quite a long conversation with John the owner, as we sorted out the confusion. As I said above always had good service from them.

It looks like they have just been overloaded, plus I have missed a call from them. All now resolved. I have have always had good service from TJD in the past, and no doubt will continue to do so in the future. Edited By Chris Marshall on 16/12/2019 15:38:50

Posted by Brian Hammond on 16/12/2019 11:29:24: Hi Chris, any luck with your parcel from TJD? No I've heard nothing. I was actually wanting to cancel the order as I realsied I had made a mistake. It was the Acrowot kit and I wanted the deluxe version not the standard.I was hoping to catch it before it was sent to avoid the bother of having to send it back. I'm hoping it's just a temporary problem with them and they resolve it soon, otherwise it will mean claiming off the credit card. Edited By Chris Marshall on 16/12/2019 12:04:17

They have not responded to my email either. I would expect them to do that outside normal hours. I would have expected something in a week. Maybe they are just very busy,

Anyone know what the situation is with TJD? I placed an order online about a week ago and have not been able to contact them about it. The phone messaging service is now full.

Glad you got it sorted Allan. It didn't occur to me that it might be a channel order problem. It should have done as the Spektrum model I set up recently was an Opterra with AR636 receiver and I had trouble with the channel order. Binding was no problem, but the ESC did not arm. The servos moved but on the wrong sticks, so it was just a case of changing the order until it was right. Of course with a quad there are no servos so it is not so easy to determine what is going on!

Glad to be of some small assistance. Yes mine lists H8S3D as a sub protocol, but there is also a H8-3D as a separate protocol. I assume that there is some difference, so it might be worth trying that. Nothing to lose.

Allan, yes I'm using it in serial mode. I get a solid red shortly after power up. As the JJRC67 is not listed I think it may be worth trying all of the protocols listed as used by that manufacturer. The one I memtioned, H8-3D is not available as a Bayan sub protocol, but is as a separate main protocol further down the list. Possibly others as well. As far as I know everything that is available in PPM mode is available in Serial mode, but I haven't tested that theory out! I've not tried to use it in PPM mode as I would lose the telemetry from the one model I have that is on Spektrum. (AR636 receiver)

I have one of the modules and have just had a play with it out of curiosity. Up to now I've only used it for Spektrum stuff. Looking at the Bangood page to (which you have linked already) there is a link to a list of protocols and manufacturers: Protocols Looking at this the manufacturer ( JJRC) uses more than just the four you have mentioned and are found as sub-protocols. For example H8-3D which is further on from the Bayang ones. Might be worth a try. I haven't done an exhaustive search for all those in the list though, so there may be others to try as well. I'm using an X10S but I don't think that would make any difference in this instance.   Edited By Chris Marshall on 29/03/2019 01:01:20 Edited By Chris Marshall on 29/03/2019 01:08:46

Normally first-aid kits are in a green box. This is in a Grey box- presumably because of the cable-ties? (Although they look a bit small to me)

Thanks to those who pointed me to the handbook. I guess I should have looked there in the first place. It's not that I never refresh my memory of the handbook, just that I haven't looked at that part for quite a while. Everything I was looking for seems to be there including a definitive statement of the point on which I have had conflicting statements. I think that I would withdraw the last paragraph of my first post, it is not valid, I was just looking in the wrong place.
