Hi Scobie,
I think I saw it on the Hitec website on the servo's page or in the servo
box. The motor windings are pretty slim, and higher voltage cretaes higher
draw, so maybe they thought 4.8 was enough. I will post the actual note
later when I can get online a little longer.
I am glad to hear that no one is having trouble with 6v on these servos,
since I would like to use them that way too.
