Electron Retracts ER40 Combo W/ GS200 For The Viper Jet 250

The ER-40eVo is our standard size retract system for models of up to 17kg (38Lb).  It is the result of extensive evolution of the first version of our ER-40 which has quickly become the most popular electric retract in the world following its first release in 2007.  The experience gained with the ER-40 has helped evolve and perfect the running and performance of this latest version, its main features being:

​

• Compact design: The ER-40eVo main frame is milled from a single aluminium block, housing a spindle system with internal absorbers mounted between three bearings (two axial and one radial). All parts are very well protected inside the strong main body.

• Light, strong and precise: The main body is milled from a single block of 7075 T6 aeronautical aluminium. Electron uses the latest industrial milling machines allowing the highest accuracy on all parts, resulting a system that is strong, smooth and without play.
