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.
Piermario Cavaggioni and his team mate have complete all test in the workshop. And they have move on to inflight test. Piermario have made a detailed worksheet with data from two test flights. If you are interested, the worksheet can be downloaded here F5B_flight_test_ZEPSUS
I have been contacted by several interested who want more technical details on the Magnetic BEC 7A. For those who can not wait, here are a few headlines.
Input voltage: Designed for 2s Lipo/Liion/LiFe
Output voltage: 5.7V
Output current continuous: 1.75A if used with 2S lipo (7.4V)
Output current burst: >10A if used with 2S lipo (7.4V)
Dimensions including heat shrink: 40 x 15 x 5mm
There has been an increasing demand for small form factor equipment in new competition planes. It’s one of the reasons why we, in cooperation with the Italian F5B team, have made this new medium size Magnetic BEC 7A. In terms of output power level it’s between the two well-known versions Magnetic BEC 14A and Magnetic BEC 5A. Piermario, my team contact, to the right and Alex his friend to the left, will the next few months test the new version of magnetic BEC. If everything goes as expected, they will be put on the webshop this spring.
The output voltage of the New Magnetic BEC 7A is 5,7V to minimize power loss and increase output power. The wires are upgradet from 0.25mm2 to 0.5mm2, same high-quality wires as the Magnetic Switch 7A.
The new Smart Magnet Holder has a beautiful design and a very strong magnet. The strong magnet extends the activation range by 3 times. Which makes it easy to switch on and off our products. The New Smart Magnet Holder is in stock and ready for sale. New Smart Magnet Holder
A review by Pierre Rondel can be found here link
The Magnetic BEC is now ready for sale. Have a look on the 14A Version specifications. Pretty impressive I think. I have been very focused on safety and hence also a very high quality. Hope you will like our new Magnetic BEC.
After having built over 15 prototypes in search of the perfect linear BEC am I finally finished. I’m proud to present my two new products. The small Magnetic BEC is for DLG gliders and the large is for F3F, F3B and F3J model gliders. They are designed super slim to fit in a small fuselage. They are both out in flight test right now and will be ready for sale in about 3-6 weeks.
Here are a few specification highlights
Only 4mm thick including heatsink
Ultra low stand-by current 5µA
Output current burst >30A
Ultra low voltage drop for safety
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
I constantly look for better components for my switches. I want them to stay as the best and most stable on the market. I found a German quality cable from www.muldentalelektronik.de It is my opinion that they make some of the best cables in the world. All Magnetic Switchs will now be made with this cables. In the long term it may lead to a price increase, but for now the price will remain the same.
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.
