RE: Magic 60
Well, here my two cents.
The teacher that learned me to fly did had a lot of airplanes, including a Curare 40 , 60 , and a..Magic, all being MK. He simply loved the 40, which was his training plane, and survived a lot of crashes, hence the installation of a .50Fsr.
Every flying day, he normally flew the Magic as well, and the thing flew as good as the curare, but being a little more 'agressive'. One time, I had to take over in flight the Curare or Magic, I was to nervous and excited to notice, anyway, that made me a fan of these airplanes.
Then came a time that he started to crash an airplane each flying day. That was also the fate of the Magic, that plewed from very high, full gas right down, in the -10°C soil, burrying it at least 60 cm deep.... Detail ? the engine survived...
Glas/Foam kits tend to be heavier...
