Customer Reviews

powerful servoIt's been my experience that HPI doesn't use very strong servos in their electric RC vehicles, and my HPI Wheely King was no different. However, after I converted it into a rock crawler, the stock servo could just barely move the steering linkage. I bought and installed this servo, and I got my steering back, even with the crawler's flexible plastic parts used in the steering linkage. Highly recommended if you need a good strong servo. 5good qualitygood quality for the money.. Comes with servo arms and HD wires.. good torque for larger planes.. I like these servos.. 5Pan servo for antenna trackerI needed a servo for my antenna tracker.This servo worked out perfectly for the pan!pretty fast response and ample torque. 5Replaces RC Nirvana sail boat sail servoTried many other servos from club members to replace RC Nirvana sailboat sail servo that would fit the servo arm, none worked. Recommended this servo from rc sail and the servo arm fits the gear and works great.Probably would also work for the rudder servo, have not tried it. 5Pretty good servo.Pros. High torque servo that is on point with its tracking. I marked on some card board the neutral spot, moved the servo back and forth for 2 minutes it always returned to the neutral spot.Good aluminum case and it feels solidly built.It is also quiet at idleCons. It is a bit slow for my taste. Good for throttle applications but I see it being too slow for steering. Most certainly not a competition servo.Wrapup.This a good servo with a solid build. Not the best on the market but it is far from the worst.This servo is a little slow but would be good for high load situations. 3weak.I bought this for my crawler and it does not turn left half the time ! It may be a fluke but the one i got was junk . 1Not pleased with this servoThis servo died after 2 hours of use as a throttle servo. Stuck open while running, but luckily I had a kill switch. Not pleased with this servo. 1I wouldn't recommend them.I dont believe the torque specification as it seems too weak. I replaced an obsolete JR servo with this one. The specifications were very similar. But this servo jitters and sometime stops in the middle of the range. Even when running without any load at all it's not smooth. I bought two of them and they both behave the same. I wouldn't recommend them. 2Highly recommend this servoThis is highest torque analog servo in Hitec product line.I bought this one for 30$, and digital servo for 70$ to compare them for robotic arm application. This one is nearly silent, and has a very strong torque, nearly as much as 70$ digital one. I would even say, that I really like the way this servo sounds while working.Digital servo for 70$ has very loud, high-pitch sound, which is very unpleasant to everybody around, and people asked me many times to switch off the robotic arm, as they did not want to hear this sound.So I am now using only HS-645MG in all robotic arms. Strong work horse servo, reliable metal gears.Highly recommend this product to anyone, good job, Hitec guys! And if you can, please silence you digital servos, because acoustics is the reason we cannot use them often :) 5If you need torque, this does the jobI use this servo to control the arms of an animatronic skeleton I set up every Halloween. I use to two of them at each shoulder joint, one to move the arm mechanism (which contains a lighter servo at the forearm joint ) frontward and backwards and the other to raise the arm upwards and downwards. While the resulting effect is very lifelike, it exposes the shoulder servos to quite a bit of stress, given they are in essence connected to the end of a relatively large "boom" consisting of the arms, especially when they are engaged in rapid movements. I initially found that the latter caused the round plastic servo horns these come with to crack, so I replaced those with round diecast metal ones that are attached to the arm connections by tightly fastened hex bolts. The only improvement I wish hitec could make to these servos would be to redesign the servo hub to accept a beefier screw to secure the horn.. The ones it currently employs are thin 2.6mm ones, which are much too light given the stresses this servo is exposed to in robotic/animatronic applications. 4
