am i the only one that goes though props? I spend hours balancing and then it seems like a couple of runs later and i need to sharpen it again. I may need to find a better spot to run, cause i'm getting tired of paying 20 bucks for a prop and then working on it forever just to have it all go down the drain, i picked up a grim prop that i still need to balance out and really don't want to destroy that one cause it was close to 30 for it, here is a video
