As I recall:
Good
- Great fun to fly, very slow in roll, soars really well but does not penetrate that well, awesome brakes
- safe for low time pilot
Bad
- Heavy to rig
- 3 piece wing is always awkward
Ugly
- there was an issue with sternposts on Skylarks 2,3 & 4. There should be inspections holes in the side of the fin (at the base) and inspection records (I seem to remember it was a mandatory and I had to borrow a boroscope to check one)
- Difficult to get any spares for them nowadays
Hope this helps
