Hi, i am designing my first frame and is a bit unsure how thick my arms should be to avoid breaking and minimize vibrations.
It's a tricopter ment for 10 inch props and will be about 1.3kg in total. And use 3110 900kv motors with a 6s li-ion battery, if this is relevant info.

So far i made the arms 225mm long (from middel of frame to middle of motor), 8mm high and 12mm wide. I belive this should be ok but i have no experience with stress testing and sutch.
If anyone have any opinions i will be grateful.
