I found the windsheild on my 'sporty forty' to be a pain. It never seemed to stay put. Glues, and pins, and tape. So much so, that I eventually just gave up on it, and flew it 'nakid'

But recently, I lost my 4 star 60. Saved the canopy though. And when trimmed right, and mounted backwards, makes a great looking 'bubble' type canopy on the slow poke!!
