I have bought this servo for using it as throttle servo in a model aircraft along with Spektrum Rx 2S LiPo HV setup. Even at 4.8v it works very fast. final setup will be 2S LiPo HV setup without any voltage regulator. This servo is really small in size, works smooth and looks very nice. I just hope that it is going to last long but only time will prove it.Naesten gratis laekker servo. Momsen skal ned i DK foer vi gaar konkursI'm using this as a throttle servo in a 120 sized plane. I selected it almost at random, just wanted a mini servo with anti vibration mounting (most mini servos don't have rubber mounts). This seems to be a quiet, smooth, fast and light servo. Being HV is nice too. Spektrum RXs are happy on HV so if you get all HV servos then you can run a 2S LiPo flight battery without a BEC.Got these thinking of going to 2S for my heli, out of 4 1 didn't work well (weak @6v) .
Unless you are running over 6 volts go with the DS-0929mg instead.Quick servo for the money, bad part is the amount of slop in the drive train when new. I heard about others complain that slop developed, but both of mine have quite a bit of play when new. Will see how they perform, but probably with go with turnigy next time.Fast and strong servo. I use it on a small Delta wing with divided ail and elev flaps.
btw that flies much better than a two flap delta with delta mixing ( thats not good for precise stearing ) The servo does what is is made for, so recommended product.Purchased 3 of these for the cyclic of a 450. The centering is horrible. Raise the stick up and let it return to center, then mark it. Then lower the stick and again, let it center. There is a 2.5mm separation. Won't even work for the sloppy clones they sell here. Waste of money.I'm using the tail of the hk 450 was very firm and obedientI'm new on helis, so...
Fit perfectly on 450 Trex Sport.
They survived two crashes.
I cannot comment on speed nor strength since I don't have equipment to measure it.
Few experienced pilots tried heli and they were satisfied with servos.
Also, servos work on 5V with me since that's what ESC gives on BEC.I used them on a 450 class Fb heli for cyclic. All 3 of them after a while was not working. Don*t recommend these
