Zepsus just released a new product called "Magnetic BEC", which combines a magnetic Switch and a 5-6V linear voltage regulator. It allows to power a F3x glider equiped with Low Voltage servos from a 2S Life/Lipo/LiIon battery. It is available in 2 versions: 14A for F3x plane and 5A for HLG gliders. Given the excellent quality of Zepsus products (I have 5 Zepsus magnetic switches in my F3F planes), there is no doubt that this new Magnetic BEC will be a best seller !
