Spot On 1.75" Servo Arm

High Quality 1.75" Aluminum servo arm from Spot-On RC

Spot On Servo Arms are made of high quality 7075-T6 aluminum, one of the highest strength alloys available for this purpose.  They feature an ultra secure double lock design, keeping your servo arm secure and eliminating any slop between the main servo gear and the arm.  Spot On Servo Arms are also sand blasted and anodized for a beautiful appearance.

Spot on offers their servo arms in many sizes, threads and gear output compatibility.  Spot On arms are offered in:
M3, or #4-40 holes, so you can use ball links that are metric or standard Futaba, Hitec or JR compatible gear mesh. Sizes ranging from 1” to 2” for single arms and 2.5” to 4.5” for rudder arms.

Available colors are Black or Silver

Spot On RC Servo Arms are measured from the center hole of the servo to the outermost hole (for example, a 1” arm is exactly 1” from hole center to hole center).  However the larger sizes offer the option of one or two more additional inner holes so you can use them for future projects or fine tune your ratios.

Redwing RC only offers the V2, upgraded version, with stronger aluminum and finer design.  No matter which Spot On RC Servo Arms you choose you will be sure to experience problem free set up and operation with these high quality servo arms.

Power HD B4S Brushless Servo - 32kg/cm (444.4 oz/in), 0.065sec 8.4V - (Super High Speed and SR/SXR/SSR/SUR/SFR Compatible)

Check out the new Power HD 0804HV Brushless servos!

These are great to use a throttle servo and can be used in systems with other high voltage servos!

The Power HD 0804HV high voltage servos are made with brushless technology. Now - we've heard about this "brushless" stuff before but it is time to ask the question on all of our minds - why is that so great? Take a brushless motor for example - no brushes in a brushless motor (no kidding...) nor does it have the commutator - instead a small circuit board coordinates the energy delivery to the windings. Think about this technology being used in a power tool - since the electronics communicate directly with the stationary windings the tool can adapt to its surroundings - only using enough juice necessary to accomplish the job. So if you are using a brushless drill to drive a screw into Styrofoam - it will sense the lack of resistance from the foam and pulls only enough charge from the battery that it needs. Whereas a brushed drill will run as fast and hard as it can no matter the job simultaneously wasting your battery life.

"What the heck does that have to do with my servo?" Well now they are incorporating that smart technology into these HD 0804HV high voltage servos - so they are not going to be sucking the life of your Redwing LiFe battery when it doesn't have to - which means not only would you be getting a great and powerful servo - it's smart! Your "LiFe" will thank you.

These servos are high efficiency and perform better. They run cooler and quieter and with less vibration - because there are no brush arcings, the radio frequency interference and electronic noise is significantly reduced.

All aluminum housing, high voltage and the new brushless technology gives you the best strength and speed while being incredibly efficient and long lasting.

So now the only question is - why are you still reading this? Go buy your Power HD 0804HV servos before they're gone!
