I see a few builds using these for hatches. What size are folks using? Round? Square? Thanks.

I use them to hold down the cowls on my 1/8 scale hydros. Most often use the 1/2"x1/4" discs-about 10.7lbs. pull. Only reason I use the round ones is I can cut a perfect 1/2" hole with a mill end and the magnets fit tight, a little super glue to hold them. They mate to either another magnet or a small piece of galvanized metal. http://www.rare-earth-magnets.com/magcraft-nsn0641/
