I don't know about the E-Flight blades. It seems when I gave them a glance at my LHS they looked like they wouldn't work on the Lama (different grip end - not sure the technical term). However, the Deal Extreme blades are MUCH better than the stock ESky blades. Certainly worth the $2.00 a set they charge. Also to clarify, by "set" I mean ALL FOUR blades. You get BOTH the upper and lower blades for $2.00.

I'm sure they're not indestructable, and probably aren't as strong as the XTreme Blades, or other white, hard blades - but they're a great deal.
