Electron ER-40 Set B (Special Order Custom Set)
Compact and powerful
Despite it’s compact size and light weight, the ER40 is still surprisingly powerful and resilient. With it’s main cage and parts being milled from solid 7075 T6 aviation grade aluminium, it is capable of working day in and day out from any kind of runway with models of up to 17kg.
Square spindle for increased speed and torque
Electron Retracts ER-40 now comes with a unique square thread spindle. This provides significantly increased torque, while also improving speed.
Designed to simply work
Retracts are usually installed and hidden away, and at Electron-Retracts we know that. That is why all our retracts have been designed to require little to no maintenance, so your time at the field can be used for flying and not fiddling.
Reversible design
Depending on your specific model, it may need the retracts to fold back on themselves, or away from themselves. Thanks to our unique design, this can be achieved by simply removing the trunnion and flipping it round. This procedure can be completed in minutes and does not affect the warranty.
Highly customisable
Choose one of the pin hole sizes to perfectly match your desired struts and combine it with one of the different angled trunnions to achieve the exact set you need.
Smooth and precise turn
The spindle system has two thrust bearings with internal shock absorbers
mounted on its head.
This gives the whole assembly a smooth and precise turn, and a cushion when it reaches the final position.
Choice of steering systems
Depending on the space available inside your model, you may be able to choose between any of our multiple steering systems, which range from integrating the steering servo to the leg (upright or inverted), a coupling system which disconnects when retracted or even the traditional pull-pull system.
