John Bitzer wrote an email to os with a wish for a switch ready to use in F5J competition gliders. Signal passthrough for Speedcontroller and redundant functionality, were some of the wishes. The final result can be seen below. Light, strong and super reliable.
Now all Magnetic Switchs comes with a sticker. Put it on the fuselage just above the Switch. With this sticker it will be easy to locate the switch and turn the plane on and off. The sticker is made of a ultra thin material, to keep aerodynamic drag to a minimum. Size is 14 x 43 mm and thickness is approximately 0.05 mm
And it is also understandable, the magnet is the key. Without it, it’s hard to switch on and off the plane.
This is why I created the Smart Magnet Holder. This solution can be clipped to your jacket or pants. The magnet is mounted on 75cm line with auto roll up.
That way you’ll always know where your magnet is.
I have been looking on the temperature specifications of the components I use in the Magnetic Switch. It turns out that I’ve been very careful when I determine the operating temperature range for the Switch (-10C to +50C). Because all the components can handle down to minus 40 degrees Celsius. The new operating temperature range is (-40C to +50C). So if there is someone who wants to go out and fly in extreme cold. They should not worry about the functionality of my magnetic switch. Remember to bring warm clothes.
First test flight on a lovely spring morning. The test went pretty good.
