How To Build The Simple RC Airplane That Can Fly With 3.7V Single Battery.

Can the entire system including the Motor, Servos and receiver be powered by a single 3.7 volt 18650 battery?

– This simple model aircraft can be flown in very calm weather, outdoors or in large indoor environments. If it is to be used in windy outdoor environments, under the wing can be
covered with 2 or 3 mm insulation foam (such as Depron). Thus, the wings will be more resistant to the wind.
– There is no Dihedral angle in the wing assembly. Because the wings are very flexible and enough dihedral angles are formed spontaneously during flight.
– The model has to be very light. That’s why the body was designed with only two layers of photoblocks. This structure has sufficient durability for flight. To make the body more robust
for impacts If you want, you can stick a 1.5mm carbon rod into the body.
