Of the mini-class servos in the CLHV family, the DS110CLHV is the fastest - 110 oz-in of torque and transiting a 60° arc in 0.035 seconds . . . this redefines fast!
When is fast important? Maybe you're outfitting a 422 Q-40 or 426 Q500 pylon racer (because you're one of those God equipped with the superhuman reflexes). Since 110oz-in is probably twice as much the torque as you need, the reason to want this servo is it's über fast response means cutting inside a competitor at turn 1. If you're seeking an edge, you've just found one.
Especially important for racing are servos built to an aerospace standard. For example, racing engines transmits power impulses throughout the air frame at 23K RPM. This intense vibration can kill servos. The DS110CLHV is tested to MIL-STANDARD 810G Test Method 514.6 (vibration), offering another edge hobby-grade servos can't deliver. How important is better vibration protection? Yeah, we think that way also.
What if you're outfitting a 500-class 3D-heli? Since cyclic-servos plug directly into a flybarless 3D-gyro - ahead of the receiver - this means corrective inputs are generated by the MEMS sensors (and significantly faster than human response). This is why top pilots use the fastest servos they can find. After all, performing piro-flips and tick-tocks so low the tail rotor nearly touches the ground means a crash happens in a flash so faster reacting servos may mean the difference between cheers, and an expensive dirt nap, right? Since there are three servos on the swashplate, one servo alone outputs more than your entire model weighs. This means 110oz-in is overkill. And since a faster servo means 3D maneuvers happen more quickly, this is the servo you want for maneuvers that stop and start in an instant. Plenty of torque, and faster means the rest of the features are icing on the cake because for you, it's all about better performance.
Ditto if you fly a 60" wingspan 3D electric down. Perhaps you want to torque roll so low you touch the tail wheel on the deck - at near zero airspeed so the forces are less important than convert thoughts into action lightning-quick or risking disastrously contacting terra firma. This is where speed counts and the DS110CLHV is the servo for your next model
With respect to centering,
Japanese Nobel potentiometer (the best money can buy) along with
components, you get the best centering in the industry.
And since the case is made of CNC-machined aircraft aluminum - plus impact
resistant engineering polymer reinforced with bronze bushings at the
steel gear shafts pockets - you get lust-worthy light weight plus
slop-free performance that endures season after season.
Better servos. The formula is simple. Decisions regarding what go into
ProModeler servos aren't made in accounting to optimize price
and profit, but in engineering. The reasonable price
comes about because we reject the importer + distributor + hobby dealers business-model because they
each get a cut at your expense. With ProModeler you're cutting out the
middlemen by dealing direct.
Note: operating voltage is
4.8-8.4V, but optimal performance is obtained with a 2S LiPo instead of a
BEC. This is because LiPos deliver the required current without
voltage spikes, noise, or otherwise adversely affecting the delicate
avionics (25C or better is recommended). After all, synthetic orange
colored Tang may have gone to the moon, but it doesn't compare to
freshly squeezed orange juice. Same thing when it comes to feeding your
foundation is the center case that's made from a solid billet of
6061-T6 aircraft aluminum. It's CNC-machined with cooling fins for
better cooling. The upper and lower case components are injection molded
of impact resistant nylon 6.6 (a fiber-filled engineering polymer like
what's used in Glock handgun frames). In the interest of durability,
plastic case components are further reinforced with bronze bushings (at
the pockets where the steel gear shafts fit). So as not to reinvent the
wheel, the output shaft spline is 25T (Futaba-compatible). For
durability, the gear train is all metal, and it's equipped with dual
ball bearings. For protection against destructive vibration, the PCB
(printed circuit board) is coated with epoxy potting compound. The
entire assembly is sealed against the elements with thirteen (13) Buna-N
synthetic O-rings. Finally, while there are ten (10) screws in the
assembly, for increased rigidity, the upper case (the one housing the
gears, e.g. the transmission section) is secured with six (6) screws
instead of four. Moreover, you get hardened (grade 12.9) Allen-head M2
socket cap screws instead of Phillips.

thing, if you're a 3D pilot and you'll trade off some speed for a bunch more torque, then consider our DS160CLHV (160oz-in vs. 110oz-in) because it transits in a mere 0.06sec/60°, which is plenty fast by pretty much any measure. Especially considering we are only competing with ourselves because the other brands can't! Finally, if brushless
motor digital servos are more your cup of tea, then you may wish to consider our DS160BLHV and DS085BLHV (this last one is 760μs neutral so it's for tail rotor gyroscopes only). With bullet-proof all-aluminum construction, these servos may better suit you needs.
are plenty of competitors, but none are
faster or stronger. And while one costs less and two cost the
same, the rest cost more! Thing is, none are built as well as the DS110CLHV - and it's not even close. Strong statement? Yup, but we can
prove it. First, scan down the list and see a comprehensive feature comparison (on a servo-by-servo basis) of the servos listed (alphabetically) below. Next, peruse the TL:DR TAB for the details of how our servo is
