Includes 2 reviews aggregated from around the web.
Well regarded for precision and durability by pilots of sport planes, gliders and small helicopters. The price is the main complaint.

Comments: Great servo, ignore the reviews from people who are burning them up as its user error and not the servo. High power digital servos require more skill to install as they need a perfectly smooth control system, if there is any binding at all the servo will destroy itself trying to center. If you have difficulty building clean smoothly operating control systems then you should stick to old school analog servos as they tolerate binding control systems much better

February 25, 2014Application(s): steering servo for electric 1/14th scale
Comments: I run a Kemora built for on-road carpet racing and this servo has worked excellent so far...a big step up from the OEM servo which was pretty weak.
The other 2 reviewers had issues and I see the 1st one ran this in a 1/10 scale buggy and the other ran a 18' airplane?
Its a mini servo guys. Do your homework.IMS000
April 2, 2013Application(s): Flap and inner airleron on 6 metre Modeltehnik Ventus 2 CX glider
Comments: These servos were recommended. I was running them at 6V through an Emcotec DPRI MV power board and burnt three out in a week for no obvious reason. Have subsequently heard that this was common experience and I've now replaced the Hitec HS 5245 MG servos with MKS servos instead. Shame as I use Hitec on all my planes and this was the first bad experience.

November 22, 2011Application(s): Kyosho Original Ultima Buggy (1984) - my retro build. Steering servo.
Comments: Buyer beware. Mine went bad, motor burned up. I am not the only one, Google this servo, you'll see. Bad example of a HITEC servo.
