RE: Magnets in our planes
Its actually a hatch not a canopy. Your right. I've heard of one guy who had his fly off(he still landed okay just need a new hatch) but it was because he was using magnets that are way to weak(not neodymium". Considering the strength of the magnets, the low weight of the hatch. and the already tight fit I think it should work fine. Any other way I have seen to hold the hatch on is very ugly or to much of a pain since you have to remove it to take off the wings. I agree that magnets are probably more prone to failure but why must they be 100x stronger than a blind nut
