Hey Adrian,
Sorry, only see this now!
No, mine is an original Alpina, from the early 80s
(yellow stickers and all that). Still have it of course
Never heard of an Alpina CS :?: Must be from the Contest Line or maybe it is the full name, but that is still an Original one anyway
Earlier that the Alpina Magic (early 90s and up to 4.4m with wing extensions) and of course, the Alpina 4001/5001 (2000s I believe, 4 and 5m WS respectively).
Little Keith have an alpina 4001
On a side note, I think I have posted this before , but Topp-Rippin is re-doing the original Alpina (called the.. Alpine) with the original Ritz2 or 3, can't remember. Handy for people looking for spare parts to keep the old lady going!
Mine in flight
