Today before flight I noticed that tail slider partially disassembled.

Please check them before each flight.

Align design is using thread. Assault design does not have thread. It is fixed permanently.

After few dosens of flights one failed on me. It can be rapaired with thread lock and manual press. Probably I will fix it this way but I decided to buy Align part for piece of mind. It is not nice to crash 700 or 800 heli.

I was lucky to find this before flight.

Here more details how to fix it:

Mine happened as well (even though I thoroughly reviewed it at nuild time and before each flight). Mine somehow slid out during lift off (aprox 30% throttle) which of course caused a horrible spin. I landed it safely with only minor blade damage which I replaced with new Zeal energy blades and never looked back. Since then I have FULLY rebuilt the tail with locktite holding her together so I 100% AGREE to check the tail slider!!
