Are the servo arms a known brand. They look a bit like some of the Amazon Chinese ‘Cheesaminium’ material arms. Some of those I can cut in half with side cutters! If they are soft they could bow under load.

The aluminum servo arms are from Futaba. I looked at others from F3A Unlimited but decided the smart move is to go with Futaba arms for Futaba servos.
