You couldn't get the mods done for that price. It's always good to add another prop to the prop box. It sounds like a good prop. If there's no damage to it, it's not a bad price. Check for cracks near the hub, dents or chips on the blades & that the trailing edges of the blades are lined up straight. If they look off it's a sign the prop has hit something & is out of whack.

With the mods done to it, that prop should rev out easier than a stock X472.
