Servo Arms

Unlike competitors, we have these servo-mounting screws custom forged right here in the USA. While there are 4 in a pack (enough for one servo), they're also available in quantities of 25, 100, and even 1000 (for professionals builders) because they're useful for a lot of other stuff like mounting cowls, landing gear straps, etc. What motivated us to make these? I was installing servos using a long skinny Phillips head screwdriver. It slipped off and punched a neat hole through the top of the...

Supplied 2 in a pack, click the pull down menu for quantities of 25, 100, 1000.These are the best screws available for securing the servo-arm to the splined output-shaft of metal gear servos because they're Made in the USA of high strength grade 10.9 alloy steel and have a blue patch of thread-locker preapplied (for vibration resistance).Competitors and experienced customers alike know ProModeler include the industry's best servo mounting-screws (#2x3/4" Allen head - https://www.promodeler.com/...

Made of heavy duty plastic (technically a fiber-filler engineering polymer like is found in 9mm handgun frames), this tough servo horn is suitable up to 630oz-in. Dimensions: ø6mm, 25-spline (Futaba-compatible) 1st bore: 12mm2nd bore: 15mm3rd bore: 18mm4th bore: 21mm5th bore: 24mm

Made of heavy duty plastic (technically a fiber-filler engineering polymer like is found in 9mm handgun frames), this tough double-arm servo horn is suitable up to 400oz-in.Dimensions: ø6mm, 25-spline (Futaba-compatible)1st bore pair across: 24mm2nd bore pair across: 30mm3rd bore pair across: 37mm4th bore pair across:43mm5th bore pair across: 49mm

Made of heavy duty plastic (technically a fiber-filler engineering polymer like is found in 9mm handgun frames), this super tough servo horn is ideal for use in steering mechanism of RC trucks - suitable for servos up to 630oz-in. Dimensions: ø6mm, 25-spline (Futaba-compatible) 1st bore: 15mm2nd bore: 20mm Nothing is unbreakable. Least of all a servo - ours or anybody's. Yet we see guys attempting to create an unbreakable truck by replacing plastic components with aluminum ones - and the first...

21mm in OD, the round servo-horn is often referred to as a wheel-arm. Injection molded in rugged nylon 6.6, which is a type of heavy duty plastic (fiber-filler engineering polymer), this is the same stuff used in 9mm handgun frames because it's so tough. Simple in appearance but complex in execution (what makes making these actually rather pricey), the molding for this arm has a total of 13 bores (that's what we call them, but everybody else calls them holes). Of course, there's one on center...

Often used for crawlers (steering), helicopters (cyclic), and model airplanes (throttle, aileron, elevators, and flaps), this servo arm is CNC machined from a solid billet of 6061-T6 aircraft aluminum. Working to its strengths, it's slender vs. bulky to optimize strength at the expense of mass (less bulk means less force wasted accelerating dead weight). Have you ever heard how cars are designed with crumple zones to protect occupants? This ProModeler servo arm is similarly designed, e.g. the...

This 2" long servo arm is CNC-machined from a solid billet of 6061-T6 aircraft aluminum then red anodized. Broached to fit 25T, it fits ProModeler and Futaba servos. Perfect for heavy duty applications whenever you need a lot of throw, it features a dual cinching M2 Allen head machine-bolts to help snug it to the splines (for extreme flight loads). Drilled and tapped for 4-40 threads in three locations, these are a great addtion to your model.Dimensions: 25-spline (Futaba-compatible)1st hole:...

Often used for high horsepower hydros (boats), big tire crawlers (trucks), cyclic-duty (helicopters), and even the odd model airplanes (aileron, elevators, and flaps on fast movers like jets), this single-horn servo arm is short and stout (and somewhat reminiscent of a fire plug). CNC-machined from a solid billet of 6061-T6 aircraft aluminum, its bulky look tells the full story because it's really, really strong! With two M2-Allen head machine-thread Grade 12.9 bolts for clamping the...

This polished aluminum giant-scale double-side servo arm is red anodized and laser etched after being CNC-machined from a solid billet of 6061 T6 aircraft aluminum. Broached to fit ProModeler (and Futaba) servos (25-splines), this unit is perfect for heavy duty applications like the rudder because because it features dual clamps to help secure the servo arm to the splines (necessary for extreme flight loads). Drilled and tapped for 4-40 threads, this is a smart choice when high flight loads...

This is the steering arm you want for installing a standard-size servo in an X-MAXX to keep the 10mm ID bearing. You also need a #7749 Traxxas servo adapter. Anyway, while we're perfectly happy selling you just this servo arm, we'd like it better if you also got our DS630BLHV servo at the same time. But we know we're losing some sales to the SAVOX SB-2290SG, and while it's a pretty good servo, we think ours is better . . . and think we can prove it. Click on the Comparison tab above to see:...

NOTE: this servo arm has a 5mm vs. 6mm spline - it's expressly for DS145CLHV micro servos only!Injection molded of fiber-filler engineering polymer, this white color single-horn micro-servo servo arm is a great choice for high performance models. Designed with 4-holes for plenty of adjustment, it's strong enough for high flight loads, but designed to break during hard impact (acting like a fuse) thus, helping protect the servo.
