Blades for me are the biggest thing I replace all the time so I buy them cheap and bulk. I usually buy 20 sets for around $12. Same quality as the stock blades so they will break when you smack something pretty good. I CA'd the other plastic bits when they cracked or broke but thats about it. You should be breaking less on the Lama as you get better at flying. These aren't trick heli's but for fly'n in cicles and back and forth in a small windless area. The only upgrade I'd get is the longer center shaft. to keep the blade strikes down. Other than that... IMO the other stuff just isn't worth it on this heli... unless its your only heli you are planning to stay with.

happy hovering
