The original tail is probably the most fragile part of the Lama V3. It broke on my very first flight (ahem, first crash, I should say). For the longest time, I've been repairing it with super glue. However, I think it has more glue than original plastic now. A few weeks ago, it just completely broke.
Then I discovered the Xtreme Flexible tail. I ordered it on ebay for AUD $25 + shipping. And it hasn't broken since. It's probably the best upgrade you can get for this heli.
Grab yourself one. Highly recommended. Enjoy!
