Hi Graham,
I can well imagine your frustration and my apologies! When I was creating the Downloads page and other sections of the site I wasn't really thinking of people building their own, but now that is the only option you are right this information should be more prominently displayed. I've added a couple links to the TCB Hardware section that will hopefully help others avoid this kind of head scratching.
Thank you for the recommendation and I wish you success with your boards! If any other questions arise please don't hesitate to ask.
For anyone else at this stage, here is one of the links I posted, which explains the one-time bootloader process on blank chips:
Flashing Bootloader to Blank ATmega2560
Thank you Luke, I'm sure those links will help someone out.

Hi Chi-el,
Sorry for the slow reply. I think the problem is almost certainly that the processor needs the bootloader installed first. When the board was under production we did this at the factory, but if you are assembling one from scratch then you have to do it yourself. If you buy an Arduino Mega the bootloader already comes installed, but when using a new chip it is blank.
The bootloader only has to be installed once on each board, after that you will not need to do it again. I've attached instructions for how to do this, you will need to buy a USBASP device. They are very cheap, here is one from China but you can probably find European sellers on eBay who have them. Notice the one I linked to gives you the option of buying an 8-pin to 6-pin adapter, you will need this version because we use a 6-pin ISP port on the TCB. Most places sell them with the adapter included.
In the instructions I discuss a pogo adapter, you won't need this because your boards already have pins installed on the ISP port, so you can just plug in the 6-pin cable from the USBASP directly into your board.
The instructions also mention using an FTDI adapter to load the firmware. You can ignore this and just your USB cable to load the firmware as normal. The FTDI adapter is faster when we are flashing hundreds of boards, but you only have to do two of them so it's no problem.
I hope this helps, let me know if you have any questions!
EDIT: No, it doesn't make a difference what position the fight/repair switch is in.
Gosh, I sure wish this was posted in the TCB portion of Downloads! I have been scratching my head as to why my finished TCB boards (3 off) would not talk on USB, even going to the lengths of changing out one of the FT232 ic's in case it was a fake. Everything working fine now but sheesh that was a voyage of discovery I could have done without!

God Day to you Luke,
i am fine and the Life in germany goes expensive...
Yes, your´e right, the chip shortage and high prices reduce the number of users.
Every open panzer board that is offered somewhere is always sold very quickly - but that doesn't mean there are more of them.
It is all very well documented, but there are no new boards to buy...

Hi Jürgen! I hope you are doing well in Germany. Well anyway I am still here lurking. Maybe the board has become so perfect there can be no more questions?  No, I don't think that's it.  But since no one can buy one for many years, and it is very difficult to build (maybe impossible now with the chip situation) I am not surprised it is quiet here.

Nothing has been written here for many days ...
Is there no longer a TCB user?

Thanks Rongyos, it sounds really good! I posted them to the GitHub where anyone can download them.

Hi Luke!
I made a soundset for KV-1 (only engine). How can I share with the community?
regards
Rongyos

Thanks Luke. I completely forgot about the different pin connections. thanks for the feedback.

Hi Mitch, I have not tested the Heng Long 7+ boards, but it is my understanding all HL boards from 6 and later use the Tamiya IR protocol, so yes it should be compatible with the TCB and with any other board that uses Tamiya, which today is basically all of them.
The Heng Long IR receiver you linked to should work with the TCB, again I have not tested it but all these receivers are generally about the same thing.
However you will need to make sure that you connect the pins in the correct order. On the TCB the Apple connector is 5 pins but the Heng Long receiver is only 3 pins because it does not have a notification LED built in. If you look on the bottom of the TCB board you will see the three pins that you need for the receiver. The pin order is not the same as the Heng Long plug, which uses + - S (connection CN16 on the TK7), but on the TCB the order is + S -.
So you will have to re-arrange the connections, but otherwise I'm guessing it will work.
