Ya, I've read others who similarly lost the hatch with bad results....hmmm lol. Anyways I've modified mine pretty heavily, and don't think that will happen in this bird. As you can see I've used 4 small rare earth magnets, two of these things probably would have done it. Also the box I made from balsa slips into a "frame" so to speak in the fuse, nice and tight. (My fingers will still be crossed tho!)
