Given your other thread, this is going to be a learning period huh? So condolences to you, but we all go thru this phase and it is the ideal time to learn to do your own repairs on a cheaper board.
I suggest do a bit a reading about board repairs, like on boardlady.com.... go buy yourself $30 of resin, some q-cell and some fibreglass. NOT anything from hardware stores it will melt your core. Make sure you use epoxy resin.
That Drops will be so fragile as to be almost asking for broken noses in a catapault. So you won't make it any worse by beefing it up a bit.
Keef is right though, it may look like just a crack but there will be all kinds of stuff going on inside if it is a foot long

so don't just fill it.
