    Application(s): Hanger 9 Twist 60

    Comments: As I said in my last review, just quit working. Today, a club member had his stop working on aileron. Luckily, plane was on the ground. There’s a problem with this particular servo. Stay away from them.

    Application(s): Arrowmaster 15cc(gas) Model Airplane

    Comments: Servo froze, just on the 5th flight. Futaba 7C Radio and NiMH 5 cell used. Unfortunately, this servo was on elevator, thus destroying a Alien Arrowmaster 60(Evolution 15cc). Junk servo. does not handle vibration.

    Application(s): Electric 50e extra 260

    Comments: Had this in my extra 260 50e running electric 5s setup and it (the plane) got thrashed every outing with lots of sports and aerobatic flying for a year and a half until radio signal failure was the end of the plane these are now in slope soaring wings continuing not to fail. As per usual pick the servo for the right job and limits always go a bit overkill if needed. Would buy again

    Application(s): In a Great Planes Escapade MX.

    Comments: Had elevator servo fail. Would move, then lock, then maybe move again. Had 3 flights on this plane, servo new. Total loss. I have many more in other planes and will be replacing them before I lose another. There is a cure. Futaba.

    Application(s): claw manipulator servo in FTC robot

    Comments: The servo horn as shipped is screwed on too tightly. We end up stripping screws while trying to remove it about 70% of the time. Hugely frustrating.

    Application(s): Cyclic servo on electric raptor 550E Helicopter

    Comments: Crap servo. Motor in servo burned out with normal sport flying, and crashed my heli.

    Application(s): Airplane ailerons and elevator

    Comments: Not sure if the servos are the problem but I have lost 5 planes in the last year with sudden loss of control. Using a Futaba 6J and R2006GS and there is some question about compatibility with the S-FHSS frame rate. Had one plane that started wild aileron chatter and melted extension connections before flying. HiTec said that both boards were damaged. Something not right here.

    Application(s): 50. nitro heli swash

    Comments: Lasted 5 flights before one failed, motor burned out. Absolute rubbish.

    Application(s): 1/4 scale airplane with 30cc motor. used as throttle servo

    Comments: these servos are failure prone with any vibration the electronics are fine but the motor is junk and burns out easily with vibration. I've had 4 failures 2 as throttle servo and 2 as elevator servo. i am taking these out of all my planes

    Application(s): Elevator with gas engine on approx 1.5M wingspan

    Comments: Have lost 3 planes due to these servos fitted to the elevator.
    On all three occasions I recovered the pieces and performed an autopsy. Each time the result was the same, the motor in the servo. The electronics board in the servo faultless. Removed the motors each time and tested them, dead spot. Turn the armature and it will run. Stop the motor, re-apply power, no go. Having said that, these servos had been in use ranging from 1 year to 18 months, so they had done a fair bit of work, but even so one does not expect to suddenly loose a plane, or have to renew the servo once a year? Someone at the club suggested the gas engine produces too much vibration and I should rather fit HS-645 servos. I really don't know what to do? It's a bummer flying and not having confidence in your equipment :-(

    Application(s): Ailerons, rudder, elevator and throttle on an Uproar 60 running a Saito 91

    Comments: I lost the rudder servo after the second flight. Was checking the plane over preparing for my third flight and it was toast; no response at all. I replaced very servo but the throttle with high-torque metal gears that same day, but kept the throttle servo in place. One day two flight number 3, the throttle servo failed. Luckily I was practicing low speed approaches and was lined up with the runway with the throttle most of the way back. I was so shocked when it failed I bounced the plane slightly when I set her down and chopped the ground with the prop (I only have about an inch of ground clearance when the plane is level) or it wouldn't have stopped rolling until I hit something. Do NOT buy this servo!

    Application(s): Elevator Servo for Escapade 40 (Sport)

    Comments: This servo just failed on me today, I was flying normally, then I just come over the foot of the run way, maybe about 15-20 feet in the air, then suddenly without warning, I have no elevator control and the plane just slowly pitches down (while I pull the stick all the way back)and I watch the plane crash into the runway. Total loss. This servo lasted for about 6-7 months before this failure. This servo MAY be good but it WILL fail after a few months of use!! This happened THREE times. All in the same airplane and all the same failures! Buy Futaba NOT Hitec!!!! You have been warned. But the S3004 for standard servo or bu the S3010 for a stardard high torque servo!! Both brands cost the same and Futaba will be WAY more reliable! I rated 2 stars because for the time it lasted, it did perform well but then it suddenly stopped working. Everything was plugged in. Even 4 senior flyers at my club agreed the elevator servo was toast. I will not buy Hitec again.

    Application(s): ailerons on a 28% skylane 182

    Comments: I wanted to put Hitec 645MG on here, however after building a bird this large and all the expense, I got stupid and originally put "High torque" towerpro servos in this position (talk about junk), so then I went to the HS 485HB, this servo has been about flawless for me.

    My suggestion is if you are stripping these then you really need to "PROPERLY" identify your torque needs, when every I hear of "stripped out put shaft" or "burned motor" its mostly that someone has undersized for the application, I took 1 of these apart to look under the hood, good soldering, good wiring, decent gears, unlike the previous towerpro's I used, both failed due to poor soldering on the motors, I have repaired both of those servos, but they suffer from over swing, and centering issues, they will be fine on a car or a boat (if you fix the issue)

    but the hihtec is a better choice for me

    Application(s): Throttle/brake for 1/10 nitro monster truck

    Comments: Lasted about half an hour and motor brushes are cactus. Bought a replacement thinking it might just be bad luck and lasted about 1 hour before same thing. The electric motor in these are not up to the task. Have triple checked linkage set up and all is good with no undue load on the servo. Definitely not fit for purpose.

    Application(s): Rudder + Elevator on 60 size EP-plane @2.5kg

    Comments: Keeping the price in mind it is in fact a very nice servo. Until now just 3 flights but no complaints.

    Comments: Nice

    Application(s): elevator for ultra stick .46

    Comments: 2 months old and it failed causing the plane to be completly demolished and the carb broke off in the block on impact, ruining a new engine.
