TGY-811 Slim wing servo's

The TGY-811 and 839 slim wing servos can generate 8 and 9 kg/cm torque. They are however supplied with flimsy plastic servo arms. These arms do not take the maximum specified torque. Arm bend or beaks and or sprocket shears in the plastic arm. I have two servo's built in my scale glider stab/elevator and will not risk a crash due to these plastic arms. As a duty of care a metal arm should be standard issue with these servos to match the specified torque . I tried to order some metal arms but are out of stock, probably other customers with the same problem or opinion

    Another no stock issue, common with HK
