Thanks all,
Nearly all closed up now. Just got to get the PE seatbelts sorted. This one is going to be out of the box and the PE is diificult.
Buxby - I tried in vain to find sources for the wiring for the radio and got zero - a subject worth knowing more about. In the end I just took a punt based on some previous builds of the DFW. I figure the aerial tube must connect to the set and the winder generates the set. So from the aerial tube a connecting wire and from the winder a copper wire through to the set. This is all made up!

I know nothing about radios and if any one else does please comment. But, like much, it will all be invisible anyway.
Cheers
Alistair
