Airtronics calibre micro computer radio control system. I first obtained one of these a few months back, basically won it in a auction for less then £20, it wasn't in the best of shape but the Airtronics were and still are the finest controllers for sale. Sanwa made and very popular in the professional race seen in the 80's and very much so today but highly expensive and well beyond the range of most RC collectors. Current models are up and over £400 and even futaba are second place in this field. The version you see here has had several donor parts as this one came from the USA in very near mint condition. I only needed a couple of parts to finish it off, luckily the calibre came complete with manuals and crystal flags and battery's plus original receiver. It's one of the very first computer transmitters with a high degree of adjustment, when you take one of these apart you can exactly see why in its day was very expensive. There are many components in the construction of this and you know where your money has gone compared with modern Radio's. It's a amazing piece and very hard to find.
If anyone out there can help me with the exact year of release as I am unsure, thanks for looking and any extra info would be great.....
