Adapter, Cross Beam Swing
Price: $39.99
Availability: In stock
Item #: PDRS-SWING -

Cross beam swing is used with the DS905BLWR servo in motion control applications. Cross Beam Swing Conceptually simple, beams and wheels sets are the foundation of making tricky adaptations. But what if you need to pivot and load, both? Enter the Cross Beam Swing accessory! Combining both a mount and an output arm, one which is concentrically supported 180°from the output, this may be one of the most time saving accessories ever created in the motion control world. So is 'this' the best way to...

Adapter, M2S, hardware
Price: $2.99
Availability: In stock
Item #: PDRSM2S-hardware -

Some modelers think outside the box. These are the guys who look at the incredible performance of the new breed of mini-class servo and think, "Wow, that's better than many standard size servos, what if I used these instead and saved weight?" Well now you can by using this mini-2-standard adapter, which is CNC-machined of aircraft aluminum for the purpose of installing a mini-size servo in the place of a standard-size servo. Making it convenient to fit minis into planes designed for standard...

Glitch Buster
Price: $4.99
Availability: In stock
Item #: PDRSGB -

Concerned regarding voltage drops due to using high power servos? While a power compensator is often called a glitch buster, what's actually happening is the current draw temporarily exceeds the capability of the power subsystem (typically the regulating circuit within an ECS called a BEC). When the BEC is overwhelmed, e.g. unable to supply adequate voltage to your servos, you experience a hesitation, what is referred to as a glitch because control is momentarily affected, or lost. And instead...

Servo, reverser
Price: $9.99
Availability: In stock
Item #: PDRS-reverser -

Sometimes you need to reverse a servo and doing it within the radio isn't convenient, or easy. And you don't feel like opening your servo to unsolder and reverse the leads on the motor and potentiometer. Enter the ProModeler PDRS-reverser to make your life easier.

Stabilizer, output shaft, longitudinal
Price: $13.99
Availability: In stock
Item #: PDRS60-L -

ProblemOccasionally you'll find yourself in a situation where the loads on your servo result in displacement of the output shaft. Since this loading leads the servo to rock fore-and-aft longitudinally on the rubber isolation mounts, this results in lost motion. What you sense in flight is a rather less than locked-in feel.SolutionA simple fix involves placing a bridge across the top of the servo, which along with a ball bearing supported output shaft, stabilizes the servo assembly on its...

X-MAXX mechanical kit, poly
Price: $29.99
Availability: In stock
Item #: S7749P -

This S7749P polymer servo mount adapter plus horn kit is for installing a series II standard-size servo DS635/845/1155BLHV into a Traxxas X-MAXX. This will not work with series I servos, like DS505/630/930BLHV (or compatible like Savox 2290SG). Instead, order control horn PDRS19F-25T, and Traxxas' polymer mount adapter, #7749. Heads up . . . our alloy series II installation kit is a smarter buy. The alloy-kit is both stronger 'and' significantly more rigid, 'but' it's only for series II super...

Price: $39.99
Availability: In stock
Item #: S7749A -

This mechanical kit is for fitting ProModeler DS635/845 or DS1155 standard size servos to an X-MAXX. This does not fit other brand servos and is not for sale separately. Kit includes mount adapters, servo horn, and hardware. Background: With the X-MAXX, Traxxas unleashed a beast on the modeling world. As delivered, it's a great introduction to the sport, but skilled drivers soon discover the limits of the stock steering servo. While Traxxas offer metal gear upgrades, they ultimately responded...

4-tap (Power Expander XD)
Price: $9.99
Availability: In stock
Item #: PEXD -

We call this thing a 4-tap because it literally lets you add another pair of Dupont discharge connectors to one of our batteries (total 4) via the XT30 discharge connector. - XT30 female close up reveals male pins - but - it's the housing that determines gender So why add an PEXD (XT30-DupontX2 power expander) to a ProModeler B2S-series LiIon battery pack in the first place? These packs range in capacity from 850-6000mAh and are a handy way to power something other than a receiver and servos -...

Direct Power-Dupont
Price: $9.99
Availability: In stock
Item #: HV2SV-D -

Power the steering servo directly and independently of the BEC with a dedicated 2S pack via a pair of Dupont connectors. Servos have 22AWG leads, the special harness is built with and has a pair of 20AWG leads (thicker) so that's the how for making more current available for it. So this harness is only for Traxxas owners running stock 6V rigs because otherwise, owners of Futaba, JR, KO Prop, etc. radio units accept the +8V of an HV pack directly without issue. As for how to actually put more...

Direct-Power-JST-XH2 E-Revo Traxxas dual steering servos
Price: $13.99
Availability: In stock
Item #: HV2SV-J -

This is intended for micro-crawlers instead of models with hairy ass servos. Just because you can do something is not the same as should do something - capice? This is made for power the steering servo independently of the BEC by connecting to the 3S or 4S propulsion pack through the JST-XH connector. HOWEVER, the servo only gets 7.4V (2S, in other words) while the BEC keeps feeding the radio something less, often 6V while at the same time, the propulsion motors gets the full jolt. Easy...

Price: $9.99
Availability: In stock
Item #: XT30-XH2 -

The power adapter makes pulling power from a 2S pack's JST-HX balance port and converting to an XT30, easy.  This mates perfectly to a JST-brand XH connector (used for the balance connection of a battery pack). There are other types of balance connectors, battery folks use whatever flavor suits them. Thunder Power, for example uses one, Hyperion uses another, Traxxas uses another, etc. This one is for the JST XH connector. They exist on batteries to make it easy to bleed off voltage from...
