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.
