Maybe I'll just make a stupid comment, but...
I've never made a homemade PCB. Some friends of mine tell me is not hard, it's just getting the hang of it, but that means making several and learn to get things right. Surely, I don't want to destroy a plane that cost me many time, money and efforts to get flying because of a poorly-made PCB.

I've seen in other forums ideas like this, so it could work here also.
If the creator (Bigboat) agrees with the idea and there's enough people interested (so that PCBs come cheap), we could have the PCBs done by one of the many companies that make small series for a relatively small price. We should make a list with all modellers and PCBs they want to buy, and once a certain number is reached, send them to be made. Finding buyers should not be that much of a problem; I'm sure that by spreading the word at the flying fields we could soon reach the target number. The "difficult" part is finding someone who is willing to act as "coordinator", to contact the companies, pay, and send them to other users. Well, it's just an idea, don't throw too many stones at me!
