Following years of development, testing and many changes along the way, we are proud to present our new brand which will supply diverse aermodelling accessories, all with the highest quality is both design and innovation.

Electron has been working for about 2 years, on a machining process that allows to
precisely mill the grooves found on aeromodelling servo arms.

Designed to fit perfectly on your servo, produced using all the latest tech to assure a tight and precise fit and all without the need for additional side screws.



Designed to be a perfect fit on your servo, using all the latest tech to assure a tight and precise fit, without the need for second screws.


Not just another servo arm. Designed to be thicker and stronger where it is needed, and lighter and milled back where excess isn’t required.


We offer 4 different sizes of arms, each of them available in two colors (red and black).
The arms go from 10mm up to 1.75”.


As with our retracts, all servo arms are carefully milled from aircraft grade T6 7075 aluminum, with an anodised and laser engraved finish.

“Having used all kinds of servo arms in the past, you can just feel the difference in quality. With reinforcements where needed and a tight but smooth fit on the servo spline you can tell that a lot went into designing and making these arms. When installing one into a servo, you can really feel how good the tolerances are and why the secondary side screw really isn’t necessary when an arm is machined right. This has been proven by their faultless performace throughout the year long abuse that they have suffered in my daily driver, the Pilot-RC 103″ Laser.”

“After many months of tests with the electron arms in the acrobats and jets I can say that they are of an incredible quality and very resistant and light at the same time.
The teeth of the sprockets after many flights remain as they had never been used without any wear.

With a single screw it is able to ensure maximum security”
