Review by Mark DelaCruz
Got this three pack of servos to run some functions on my Easy Glider. One servo currently handles the lens position for a Flycamone2, it works perfectly. The other servos will go into another project. What a deal, and Grayson Hobby ships FAST!!! Most impressive. Thanks. (Posted on 2/11/2009)
A super deal ! ! I just put these in my modified SLO-V and they are doing a super jov. No performance gllitches. Very responsive. I am ordering three more to keep for future kits. They get my vote as a darn good buy. (Posted on 1/21/2009)
Review by Jeff Milton
These are great servos. The are fast and seem quite precise. You would have to by these from overseas to get as good a servo at a lower price.

I have them installed in a couple of high speed park jets and the control horns rip out of the foam but these servos have no problems at all.

At just over $6 each you cannot go wrong. (Posted on 7/27/2008)
