First thought: Excellent! Then: Dang it has a lot of torque. Next came: This is sweet, its got more torque than a "same spec" hitec servo PLUS metel gears for a third the price! (running 6v pack) Then came: crap, I just shorted the thing out =( need to go buy a couple of backups.
Operated my .60 retracts in a Corsair with odd linkages perfectly. No complaints except no short circuit protection. :P I will certainly be buying more.
