Switch Installation

Rather than installing the magnetic switch that comes with the Central Box, I decided to install a regular mechanical switch. It’s not that there is anything wrong with the magnetic switch, I’m just afraid of having a “blonde moment” and losing the magnet somewhere.

The functionality of the magnetic switch is that, when in the “off” position, it connects the outer two pins of the 3 conductor servo wire. In the “on” position there is no connection. This is why it is referred to as a “failsafe” switch. In order to turn the plane off, the switch must be functioning.

As an alternative, I use a Spektrum SPM6820 Soft Switch which is used with JR and Spektrum PowerSafe receivers. It’s a physically small switch which makes it easy to install almost anywhere. In my case, I installed it on a little panel glued to the front former. Removing the nose cone gives access to the fueling port, air system fill port, and the switch.
