Fabulous Servo

Building Inmoov Robot, works great!

Verry good servo!

It is a verry nice servo and it is working great! Verry good quality product.

Use high Amp power supply

at first thought those are weak. I had 2 on a 1 amp charger. When i put them on the 6 amp i was impressed with how much torque they have. Super powerful if you have the right charger. Also this is probably common in other servos too, but there is no reverse polarity protection, so plug them in right or loose 50 dollars.
