All Electron-Retract legs are milled from solid 7075 T6 aviation grade aluminium, before being anodised and laser engraved.

Electron-Retracts offer ready to run combos that are plug and play for most current models on the market.
Thanks however to the modularity of the legs, almost any length and rake can be achieved to meet your requirements.

All Electron-Retracts legs come with an easily adjustable rake, just tighten or loosen the single grub screw at the back of the main leg to determine the exact angle and wheel position for a perfect fit in your specific model.

Not only do all Electron-Retracts legs come with spring suspension as standard, but the legs are actually notched to limit the maximum travel of the lower arm, thus preventing over scratching the spring and avoids early spring fatigue.

Thanks to the geometry of the leg, an exponential response is achieved from the spring. Thanks to this, while taxiing the suspension absorbs small irregularities easily, with the response from the spring increasing exponentially in response to the higher loads received during takeoffs or landing. Always working optimally for each given situation. 

Aside from this, three different types of spring can be used on each leg (soft, medium, hard) so you can choose the optimum strength for the model and runway.
