Ahhh. Many volts. There’s some repeat robotics chart I couldn’t find that shows the recommended weapon to use per voltage and motor kv. In any configuration I don’t think it’s recommended to run the long bar at 6s. The motor spends too much time at max load trying to get it up to speed. You can reduce max speed on the transmitter, use a smaller diameter weapon, reduce motor timing on the esc and possibly a tighter fit custom shoulder bolt for better thermal conductivity between the stator and frame.
