The Dynam PBY Catalina V2 twin-engine seaplane is well-designed, and the three-piece detachable wing is easy to carry and assemble. 1470mm (57″) wingspan and dual Detrum BM2815A-1100KV (CW & CCW) brushless outrunner motors provide plenty of power, great lift force, short takeoff distance, and strong wind resistance capacity. The commonly used 3S 11.1V 2200mAh 25C Li-Po batteries can support a flight of 8-10 minutes. It is perfect for flying on the lake in summer.
