FAQ´s about Set B without Steering System (ER-40 Classic)
-
Can I REVERSE the retract trunion, or change the RETRACTION ANGLE?
This is possible only in the “reversible version” of our retracts, released from January 2015 onwards. You can find the indicative “reversible” engraved next to the serial number.
-
Can I use a 2S battery with ER-50 NG retracts?
ER-50 NG retracts are rated for 3S LiPo voltage. Therefore, the battery that you have to connect to the retract unit controller, should be a 3S battery.
With a 2S battery, the ER-50 NG retracts will work, but the speed and torque of the retract will be reduced. Depending on the length and weight of the strut and the wheel, and other factors, the performance of the retract with a 2S battery could be enough to operate properly.
-
What BATERY can I use with my retracts?
Electron suggest using a single small battery for retracts and brakes, and don´t share the receiver or engine battery.
500-900 mAh will be enough for at least 25 flights, so with a very small battery you will have power enough for a full flying day
-
What retracts can be upgraded to square thread SPINDLE?
All retracts purchased from January 2013. The serial number must start by 13, 14, 15, 16, etc… (the first two digit indicate the manufacturing year)
