Great servo! perfect for my project! The attachments are nice and large with holes pig enough to attach a hanger diameter metal rod! great power as well! for arduino, you will definitely need an extra power source, I have 4 AA batteries jimmy-rigged together and it's great!

This is one of those items that you know what you are buying and you need this one particular thing, so there is not a lot to review here. It is what it says it is. It is a Hitec servo, which means quality, and it is big, heavy and strong, which is good for a robot, not so good for an airplane. If you don't know much about servos, the one thing I would tell you is that this, like all large servos, require a lot of power to run. Do not expect to run a bunch of these off an Arduino or something like that, you will need a large battery or power supply for any kind of run-time.

Then again, if you are thinking about putting this kind of money down on a servo, you know this already. Have a great day!

I have ordered 2 of these servos. They are a good size and I use them on power wheels cars as a steering mechanism. They are pretty powerful but they do require quite a bit of power to run at max torque. The size is perfect for the powerwheels application as they sit snuggly under the car and have the right clearance for the steering linkage.
