Nope because it's not necessary. A couple pieces of spruce and a couple pieces of balsa/carbon/balsa and this thing will hold up to just about anything (except a van door, don't ask......)

If I haven't managed to break a wing ,and Emory (Mr. High Energy Snap) hasn't managed to break one, I'm inclined to think they're maybe even overkilled. But since the weight and effort is negligable, I'll leave them as is.
