I didn't see specifics on this info posted anywhere, so I thought I'd share. This is for part ARA311106, the new "6mm" motor plate. If i understand correctly, it's the new normal that's shipped on the 3s rigs. I ordered this after bending my standard 5mm motor plate (running a 4068 surpass motor), probably happened at the skate park.
While it doesn't quite measure up to 6mm thick (5.77mm in the pictures), there is increased material elsewhere. Crucially, the hole for the pinion is now smaller, meaning less material was remove from the inner walls for the motor shaft penetration. I know my measurement probably isn't super accurate, but I calculate roughly 40% more material with the 6mm plate vs the 5mm plate where bending usually occurs. Hopefully that means it's better in the long run!
While I think the thicker plate will help (a 7075 version of this would be quite stout!), I also plan to run some sort of DIY brace forward in the chassis to reduce stress and prevent bending the motor plate. I'll update with the results!
