And if MG996R is overpowered, use SG5010.
However, I feel that the size does not change that much.
The more small servo and more powerful than SG90 is MG90S.
It's the same size as the SG90 and uses metal gear, but the torque doesn't increase that much.
The MG996R will definitely rotate 180 degrees.
Some sellers also sell 360 degree items.
