    Application(s): .40 size nitro sport plane

    Comments: found out the hard way that these servos don't like 6V. Should have read some reviews on this servo, from the many different forums, before I put them in the plane .... my loss.

    Application(s): Wicked Wing, 100in glider

    Comments: These were rated 6v when I got them thinking they were great servos as far as dependability goes like all the other standard size Futaba servo I used. But these were made in Taiwan not Japan and Futaba changed the specs as they can't take 6v so can't use them and have a bunch I saved. Thanks to X-Jet I learned about the issue on the ground.
