Our history
2007 Birth of the company
- Incorporation of a 5-axis machining center, one of the first to arrive in the province.
- In collaboration with Jets Munt (Gaspar Espiell), the first turbocharger in 5 continuous axes in the world was machined for its application in model airplane turbojets, this being a turning point in the development of these engines.
2008
- Our participation in the machining of the different parts of turbojets dedicated to model airplanes is increased.
- The first prototypes of electric landing gear begin to be developed.
2011
- First operational and functional prototype of ER-40 + magnetic brakes, tested in a rc jet.
- The 1st operational version of ER-40 is marketed, obtaining enormous success.
2013
Evolution of the ER-40 to ER-40eVo. Version that will become the most manufactured train in the world in the coming years.
2014
- New 750m2 manufacturing plant with the addition of new machinery.
- Development of the ER30 and ER-50 in their eVo versions.
2019
- Automation of the production process of the landing gear structures.
- Development of the ER-50NG, ER-40NG.
2021
Launch of ER-50NG.
2022
- With more than 20,000 and 10,000 units of each model produced respectively, Evolution of the eVo to Classic versions, incorporating a new engine and receiving several design optimizations, making it lighter.
2023
Initiation of procedures for the construction of new factory with 1800m2

Our values
The Perfection of Flight
Having the necessary technology for CNC machining brings a series of advantages that benefit both the aeromodelling and UAV industry, as well as the end customer who acquires a product with components of the highest quality that contribute to precise and efficient operation.
In this regard, the machinery involved in CNC machining has evolved by leaps and bounds in recent years, and at Electron Retracts, we are the industry reference. This means that nowadays, the manufacturing and production processes to shape the parts are carried out with error margins that barely reach thousandths of a millimeter. It is a clear indication of the sector’s demanding nature, which requires perfectly fitting components to avoid possible breakdowns or failures.
