ERBE Motor Plate Brace

[mistercrash]

That stock motor plate is very flexible, it is some cheap aluminum that is barely 3 mm thick like the aluminum chassis of a nitro Revo. I tried doubling up the motor plates and they still bent. The motor/mount is heavy and they are hanging from that plate. I went back to that 6 mm thick carbon fiber plate I made and it is much stiffer and stronger but CF does not dissipate heat like aluminum does so my motor runs 10 degrees hotter. That rod looks like a good solution. The best would be a 4 mm motor plate machined from billet aluminum. Like 7075 T6 aircraft grade stuff. Strength, stiffness, lightweight and heat dissipation. While you're at it, machine the motor mount also from that same billet aluminum with larger fins for better cooling. Add a brace similar to what you did on top of that and that motor wouldn't budge at all.
