Currently (05/2018) the latest and most powerful motor from BrotherHobby.
Previous versions of this motor (R4 and R5) set the standard in terms of weight, unmatched performance and quality in the 2206/2306 class. The new R version is based on everything proven and adds an increase in size to 2207. All this is being offered while maintaining a very low weight of 32 grams, including 16cm AWG20 power cables.
Because of its power, the motor is very suitable for heavier 5-inch props, such as Gemfan Flash 5152S or Dalprop Cyclone 5046.
The new NMB 9*4*4 bearings are used on the motors, making them more durable.
Higher KV 2700 is particularly suitable for lighter propellers such as HQ 5x4x3 and the like. For typical racing propellers (Gemfan 5152S Flash), the 2400 KV version is more suitable.
