●【What is this it】This is a jet engine for model airplanes, which provides power to the model so that the model can fly. Of course, it can also be used for automated robots, laboratory aerodynamic research, high flow intake, exhaust and other applications ●【Lightweight】This is a small size, lighter weight, and high output product, and the power is very surprising, you can fly your model easily ●【Main Parameter】 Maximum voltage: 16.8 V, maximum current: 52 A, maximum thrust: 1460 g (3.21 lbs), product weight: 205 g (0.45 lb), connector banana plug: Φ3.5, electronic stabilizer: 2-4S 50A, XT60 plug ●Dynamic Balance G 0.4: Our products have extremely high rotational speeds, so the balance of balance is very important technical indicator. With the power balance level G 0.4, our products are more efficient, more energy saving, more sail longer and rivals the sound of the vortex engine ●【Easy to Use】The plug of the motor and electronic governor are they welded, so you can use it without welding after purchase ●What can you get: Each 2.5 inch (64 mm) EDF includes motor: 4S 3,500 KV, 50A electronic governa
