Maintenance of helicopters: Tail

Let's get to it. 

The maintenance of a helicopter, is something you need to do every now and then. I do it after 40 flight, after a crash or once a year. whatever comes first.

If you have other items you check plz let me know so I can update my checklist

Also I keep a log of parts i change, so I can have the most common ones in stock.

Checklist of a pro type helicopter:

• Is the tail boom bent
  
• Is the stabilizer fins cracked
  
• Is the any of the gears striped
• Is the torque tube bent or cracked
• is the pushrod bent 
• is the tail shaft bent ?
• is the tail blade holders cracked
• Is any bearings damaged

When I have it apart I always clean and relube all the bearings.
