BrotherHobby Returner R4 2206 2300 kV

The most recent and top of the line Brother Hobby product - and possibly the best motor on the world. 

The previous version of this motor, known e.g. as ZMX Fusion in one of its OEM variants, has established the benchmark of the best power, low weight and quality in the 2206 class. This new R4 version has all the great legacy and brings more improvements, like the EZO bearings (best on the market) and titanium 5 mm (4 mm hole) hollow shaft. The bearings were upgraded in size from 3x8x4 to 4x9x4, to improve the reliability and longevity of the motor. The shaft is secured by a nut (not a C-clip as is often the case).

All this great stuff for only 28 grammes of weight, which is a great number for this size class.

Beacuse of its power, the motor is suitable for the heavier props, like e.g. the RaceKraft 5051 or DAL 5X4X3 HBN. The tests show static thrust of 1400g with 5" props, 1600g with 6" pros, while showing relatively low current consumption. The efficiency is very hig (about 3.3 g/W), especially compared to the competition.

BrotherHobby motors (and their OEM versions) are used by the best pilots in the hobby.
