This servo was bought for its strength and light weight-- however it only turns the usual 90 degrees of rotation, and I don’t know how to make it turn 180 degrees. If you have a use for it, maybe an EC-12 .....  my landed cost was $27.

The Mad Max of servos.
Milled from a single block of 6061 alloy*, this servo screams "crazy tough"!
The milled alloy MG959 carries as much attitude as it does torque and robustness.
Why did we bother making a CNC milled 6061 alloy servo and then charge less than 25 bucks for it?...
Beause we can!

No amount of R/C truck bashing or plane crashes will distort this servos case.
It includes accessories and has dual ball bearings and metal gearing.
