Just been reading your posts about the Fouga Magister, and I see that Ray's PSS jets have been mentioned, also the company who supplies the jet in Question. O.k. hopefully I can answer a few of your questions!
The Person in Question from Ireland, is myself 'John Pearson'
1. The two Models designed by Ray Jones ( Fouga Magister, M339) as supplied by Dragon Aviation some years ago, will be soon back in production under the banner of Island Models, a company based in Dublin, Ireland, which supply a range of scale gliders. www.islandmodels.ie
2. The model shown in the post is not Ray's design, (it is two small). I think that your Magister is a German kit supplied by RC-Tronics-Topp-Rippin.
Here is the link to the kit:
Hope this helps
