EMAX Released New RS2205S Red Bottom Motors

EMAX newly released a upgraded version of the Red Bottom RS220S racing motors, the RS2205S. Available in 2300kv and 2600kv as the same to previous version. Purchase the EMAX RS2205S motors from FPV Model.

The completely redesigned RS2205-S is upgraded with features racing multirotors absolutely need. The motor is lighter, yields faster bell rotational response, higher thrust, uses premium materials and backed with EMAXs legendary production quality.

Lighter and Lower Profile
2 grams lighter than the first version of the RS2205, the RS2205-S is a 2205 motor which has been overhauled for the weight conscious racer. The bell has been redesigned to have a lower profile without sacrificing the structural integrity of the motor. This eliminates unnecessary mass and allows quicker rotational response of the bell. The shorter motor height allows a lower center of gravity closer to the mounting point.

RS2205-S cooling fins have been reworked to keep the motor height and weight low while maintaining functionality.

N52SH Curved Magnets:
By utilizing N52SH curved magnets, the pulling force between the stator and magnet is greatly increased. The design of the motor extracts every bit of force from these magnets and keeps it constant throughout the phases.

Japanese NMB bearings ensure smooth, long-lasting performance.

Compared to the RS2205, the new RS225-S cranks out another +100g of thrust. Paired with a KingKong 6×4 propeller, expect over 1,400 grams of thrust (Check out the full motor results:

Hollowed Steel Prop shaft and main shaft
The upgraded shafts maximize durability. No worry of damaging threads during crashes.

Bell Retaining Screw
No more E-Clips. With a retaining screw, RS2205-S has no chance of having bells pop out during a race. It is also easy to service the motor without needing a special tool.

EMAX Legendary Production Quality
Engineered and produced In-House with state-of-the-art production techniques and machines, every motor that comes out of our factory is guaranteed to have the tightest build tolerances. It is with this ability, that we can achieve 0.10mm magnet to stator air-gap and crash-durability racers come to love.


DJI Announced the New Phantom 4 Pro

Further to the Inspire 2 Announcement DJI have announce the New Phantom 4 Pro.

This new upgraded version of the P4 has had an very big overhaul since the original Phantom 4 launch earlier in the year.

The Body

The adoption of titanium alloy and magnesium alloy construction increases the rigidity of the airframe and reduces weight, making the Phantom 4 Pro similar in weight to the Phantom 4, It’s flight control system is the same as the P4 but it now uses an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support with the ability to choose between 2.4Ghz and 5.8Ghz, this allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive interference.

The Lightbridge HD video transmission system used in the Phantom 4 Pro uses TDM (Time Division Multiplexing) to transmit signals, allowing it to send controller signals and receive video transmission signals at the same frequency. As the 2.4GHz frequency band is often affected by Wi-Fi, 4G cell towers, and other types of interference in urban areas, a 5.8Ghz band will increase transmission reliability. When switched on, the Phantom 4 Pro evaluates local signal levels, automatically choosing the transmission frequency with the lowest level of interference. This ensures the optimum range of a maximum video transmission of 4.3mi (7km)*

The first big change to the P4 Pro is its now fitted with a all new 1-inch 20-megapixel sensor capable of shooting a maximum of 4K/60fps video and Burst Mode stills at 14 fps, its also capable of recording 4K 30Fps in H265 as well.
DJI say its their first camera to use a mechanical aperture, this eliminates rolling shutter distortion that can occur when taking images of fast moving subjects or when flying at high speed, Its also fitted with a mechanical focus as well, In effect DJI believe it is as powerful as many traditional ground cameras out there.

With more powerful video processing it now supports 4K 60fps video on H.264 and 4K 30fps in H.265, both with a new 100Mbps bitrate, this means the sensors and processors can captured with more image detail than anything else in this class out there.

Sensor size is more important to image quality than the number of pixels because a larger sensor captures more information in every pixel, improving dynamic range, signal-to-noise ratio, and low light performance. The 1-inch 20-megapixel CMOS sensor in the Phantom 4 Pro is almost four times the size of the Phantom 4’s 1/2.3in sensor and it uses larger pixels. Maximum ISO is 12800 as well as increased contrast.

An enhanced video processing system allows video to be captured in cinema and production optimized DCI 4K/60 (4096 x 2160/60fps) at a bitrate of 100Mbps, enabling you to get high-resolution slow motion shots.
The Phantom 4 Pro also supports the H.265 video codec (Maximum resolution 4096X2160/30fps). For a given bitrate H.265 doubles the amount of image processing as H.264, resulting in significantly enhanced image quality. Record in the high dynamic range D-log mode to make the most of this image data for color grading.

This is a huge step forward compared to where we have been with the previous generation Phantom 4.

The Phantom 4 Pro has a new larger 5870mah battery, its the physical size as the original Phantom 4 pack and is believed to be backwards compatible with the Phantom 4, this new larger capacity battery allows a maximum flight time of 30 minutes providing more time in the air to capture the perfect shot. The DJI GO app shows battery lifetime and calculates remaining flight times according to distance traveled and more. It will give alerts when it reaches a minimum safe amount required for a safe journey back to the takeoff point. An advanced battery management system is also in place to prevent overcharging and over draining. When placed in longer term storage, batteries will discharge power to maintain good health.
