Hello there I also built the Range Safety Launch all those years ago & still running & with the second I/c motor or is it the third as I gave one away and the first wore out & now have an OS 25 FSR & is a very rough water type hull as a model & cuts the rough water away very well. Anyway the item is the 'basket ' radio aerial. EASY to make . I made a balsa plug or innards. I then bent wire around it to shape and held the wire close to the balsa plug binding with fuse wire. I soldered the top and the bottom (grinding away the wire rod 'overlaps' at the top and bottom as I added more of the wire rods) & the Range safety launch has a ring on the 'middle', actually, two 'rings' which I made of brass sheet strip & rounded & then wrapped around the middle and also soldered to the basket rod wires. The whole assembly with an added scale mounting bracket was all held so firm to the charred balsa plug. When all was made I picked out the balsa innards with a pin so to leave hollow. The wire basket was cut between the two central rings as on the RSL there is a gap in the middle ( as the rings hold the rods from springing apart on the original RSL) but the previously made mounting bracket holds the two rings apart . Then all painted etc and fixed to the folding mast. The mast hinged down f'ward to allow 'shipping' when on the slips and for repairs to access the upperworks of the mast.

HI Peter,
Many thanks for your reply. I looked at the website you suggested,and another link from that one. Scanning the pictures on those sites I have enough info to make a drawing and build the missing part. Once again thank you.
overthesea. Hi Everyone,
I have a couple of questions that I am hoping someone can help me with.
About 36 years ago I built a 42 inch model of a range safety launch. The model has been gathering dust and cobwebs in my loft for the past 15 years. On moving house, when clearing the loft I found the poor thing. I've now washed and clean her up, and the motors run perfectly and the navigation lights still light up.Somewhere, (probably still in an unpacked box), are the plans but I cannot find them.
The questions are about the fixture on the foremast.
Can anyone tell me what it is? it is like a double ended basket, and can anyone help in a close up drawing or photo's of it. it appears to be the only bit missing from the model.
Any help would be very much appreciated.
Thank you.
Overthesea.
