Mini Ripsaw Robot tank tracked lower cover

I upgrade my mini robot tank from AliExpress with 800KV brushless outrunners motors. The motors: below 800KV is better for direct drive projects. I find the HobbyKing 2213N 800KV brushless motor at hobbyking.com/en_us/2213n-800kv-brushless-motor.html to be perfect. Just reverse the shaft and you're good to go. If you build your own hub/coupler, you can adjust to a specific length for aligning the sprocket with other wheels. I choose these motors because they are extremely lightweight. However, you can use better motors: hobbyking.com/en_us/ntm-prop-drive-28-36-750kv-265w.html with 3mm shaft or these motors that are more heavy with 4mm shaft. You can then use the following hubs/coupling: https://fr.aliexpress.com/item/freeshipping-2pcs-Aluminum-metal-coupling-for-tank-chassis-tracked-vehicle-motor-connector-model-fitting-diy-rc/32604718325.html?spm=2114.13010608.0.0.i4yKfb. Dual 30A HK ESCs are perfect for smooth startup with high poles outrunners motors. A programmable card is needed to tune timing settings to medium or high and startup power, while the motor is at the limit for smooth startup in direct drive without reduction gear. I find the HobbyKing R-Brushless Car ESC 30A-W-Reverse at hobbyking.com/en_us/hobbykingr-tm-brushless-car-esc-30a-w-reverse.html/?___store=en_us to be perfect for my needs.
