Which hv speed controller can I use that won't send me into bankruptcy ? That castle joint seems extremely expensive.
The stock ofna diffs do not last long with 6s power. If you use a reciever pack and disable/disconnect the castle BEC unit the MMM can take 7-8s power for a limited time.
For reliability you will need to step up to the offshore boat power plants.

You will also need to match the ESC with an appropriate sized motor. Using 8-12s will cause you to purchase a 500-1000kv motor. These things have extream torque and your diffs will not be long for this world.
You will see by the chart below your current motors peak is some other motors sustained output.
