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...

Item #: PDRS107 -

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...

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...

Item #: PDRS209 -

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:...
