When 90 degrees isn't enough...

Review by Rick Winscot

I've modified a lot of servos for continuous rotation over the years... they make great motors for little robots. However, the process is time consuming and when you make a mistake, it's like blowing your nose in a five-dollar bill. Being able to buy them as continuous rotation servos is awesome - having a trim is even more awesome-er. Keep in mind that this servo is constructed with nylon gears, an abrupt stall may destroy the servo.

Nice Servos

Review by Hamilton

Used these for a robotics and Arduino class with 5th through 8th graders. Didn't really have the time or financial leeway to go the motor controller route. All went well. I'm glad these exist, I'm glad I got em' and I will do it again.

Wish we'd known about this several months ago!

Review by Carol

We ordered some servos that we intended to hack for continuous rotation, and when the time came, they were not hackable :-( Seems like that happens a lot. You don't want that to happen at the last minute. These worked great. Thanks!

Great small servos at a good price

Review by Joseph

I purchased these servos to build an inexpensive robot. They work well. I used wooden wheels from a craft store and used double sided carpet tape to connect the wheels to the servo wheel.
