Jason Shulman's history-making electric powered world championship plane.
At this year's F3A Aerobatic World Championships held in Poland, history was made. For the first time in its over-30-year existence, an electric powered model was competitive against the most powerful O.S. and Y.S. glow-powered pattern airplanes in an FAI world championship format. At the start of the event, contestants and spectators alike were skeptical, believing that competing with an electric model was more of a publicity stunt than a serious competition attempt. But after the first flight, all skeptics were silenced and by the end of the preliminary rounds, a 4th place position transferring into the finals proved that an electric-powered model had the right stuff to compete against the most powerful glow-powered aircraft, as flown by the best pilots in the world.
The technology that's made this possible is also changing the face of electric modeling at local fields and indoor flying sights across the country. Lithium Polymer batteries are the latest technology and offer several times the capacity/run time of previous generation Nickel Cadmium and Nickel Metal Hydride batteries, with reduced weight and size. Plus the latest generation LiPo (short for Lithium Polymer) cells have a low internal resistance, so they're able to provide high amp draw for powering high-performance and even large-scale models.
Thunder Power is the current performance leader in LiPo batteries. Imagine flying a GWS Tiger Moth or FD stick for over an hour on a single charge. Or imagine an indoor 3-D model that you can hover in a small office for over 15 minutes. With LiPo batteries you no longer have to imagine, as this type of performance is now a reality.
Understanding LiPos
Lipo batteries are very different from previous generation batteries and understanding how they work, and especially how to charge them, is the key to getting the best performance.

Individual Lithium Polymer cells have a nominal voltage of 3.7 -
