Static discharge could be a problem. I had mini GDW-DS595MG servo mounted on the tail taken out by static discharge before. Changed to KST servo and no problem since. Make sure you ground everything properly.
Thank you for your input. I have the antistatic kit (connection between tail and motor mount) from Goblin for the fireball mounted and the model had more then 150 flights without issue. So its hard to believe that a static problem occured (i check regulary all of my models for loose screws, loose cables etc).
All of the (stock) servo from the kit are working without any issue.
The first flights after rebuild worked flawless (Because of bad weather on the weekend i was not able to fly anymore).
