This heavy duty DOUBLE-HORN aluminum servo arm is CNC-machined from a solid billet of 7075-T6 aircraft aluminum, broached for the standard spline (25T ø6mm), and threaded in sixteen places for M3 mounting hardware on 5mm centers. Installation is axially on 6mm diameter, 25T-spline shaft (lightly greased), and secured, then cinched with M3 Allen-head machine-thread bolts. Disassembly is the reverse, loosen cinch bolts, then remove securing bolt. Mounting positions (M3 thread) both horns 25.4mm...

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 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...

secures to the 25T spline with an M3 bolt, the three mounting points are at 10, 15, and 20mm from center. These are etched corresponding to 2.7X, 1.7X, and 1.3X respectively. CNC machined from a solid billet of 6061-T6 aircraft aluminum, this arm is strong and light and works to promote a servo's strengths by multiplying torque at all three mounting points. Bored for M3 mounting hardware (but 4-40 fits), and as always, use threadlocker. Fits any equipped with 25T compatible...

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 a great standard size servo combo for an X-MAXX because it combines the stump pulling torque of the DS930BLHV servo (930oz-in) and our custom aluminum control horn for an X-Maxx. This servo, incidentally, is equipped with a stout steel gear train, it's environmentally sealed using 13 o-rings (10 more than any other in the industry), and also meets 3 MIL-STDS (three more than any Asian import). Here's what you get in the package: DS930BLHV servoPDRS19F-25T aluminum control fork This is...
