Dragonfly Hurricane 2207 KV2500 Brushless Motor for FPV Racer


  • Specially deisigned for FPV racing with extreme performance
  • Fast response and ultimate efficiency
  • New technology to ensure smooth running
  • Precise balanced and fully tested
Powerful, reliable, and quick. This is the latest Dragonfly Hurricane 2207 2500KV brushless motor that specially designed for FPV racing and extreme performance. These Dragonfly Hurricane 2207 2500kv motors feature an open air base to allow for more efficient cooling of the motors. Weighing in at just 30.5 grams helps eliminate some weight compared to other motors and fits with most racers desire to shave precious grams off builds wherever they can.
Features:
  • Featuring 20awg silicone wire, N52SH magnets and Japanese NSK bearings these motors are sure to fit the needs of most FPV racers.
  • We use high quality aluminum and rare-earth magnetic materials, and redesigned the magnetic circuit of Dragonfly Hurricane to make sure the motors come with a better loading capacity.
  • We have greatly improved their thrust and efficiency comparing to other motors on the market. At the same time, we have enhanced the response speed to guarantee the smooth flying of your racing quad
  • The use of special aluminum material for body structure, not only comes with a greater strength than those motors made of the 6 series aluminum that most other motors use, but also greatly reduce the weight. 
  • The motor shaft has abandoned the traditional way of installation, the spindle completely goes through the threaded shaft to improve the friction between steel shaft and threaded sleeve of head cover. It also improves the concentricity of motor rotor and effectively increases the strength of propeller shaft, so that to make sure the motor can survive from the hard crashes.
  • The Draongfly Hurricane has added an insulation film between bottom cover and spindle to isolate the connection between screws and copper wires. In this way, the motor is able to prevent from short circuit and leakage that caused by misoperation.

Skywalker SMART 996mm Wingspan EPO FPV Racing Wing RC Airplane Kit


FPV wing racing is a growing quickly and has the peotential of being bigger than mini quad racing due to the facts that wings are faster than miniquads and easier to see in a race. Being easier to see in a race allows spectators to feel more involved while watching an event. 
This potential has been noticed by Skywaker and now Skywalker is throwing in their own design ideas with Skywalker Smart. Skywalker Smart is a dual motor design that is focused on serious power, allowing the user to climb to speed over 140kph. Featuring a 996mm wingspan, Skywalker Smart is large enough to get all your gear in the air but small enough to ensure lightning fast speeds with quick and agile air manuevers. Skywalker Smart can have several different methods of take off with two most common methods of take off being hand tossed or vertical launch. Skywalker Smart FPV Racing Wing doesn’t stray to far away from the mini quad racing scene and if your familiar with mini quads you’ll feel right at home with this built. 
The motors, escs, fpv gear ,and flight contollers are all the same specs that you find in your typical mini quad build. Recommended motors are 2206 2300kv with 35a ESC combinations. For awesome flight controller preformace with the much need PWM out puts servo and motor connection we recommend X-Racer F4 flight controller. You can find a review and detailed description by Oscar Liang here.
Specification: 
  • Wing span: 996mm
  • Fuselage length: 430mm
  • Wing area: 25.9m2
  • C.G.: From head to back 240-250mm
  • Flying weight: 750g-1000g
  • Takeoff:Hand cast
  • Landing: Belly Landing
  • Air speed: 60km/h
  • Maximum of flying time: 30min
Recommended configuration: (not included)
  • Motor: 2206kv2300*2pcs
