The latest iteration of the BrotherHobby Returner line.
I was very curious to test this motor essentially back-to-back with the Multicopter Builders Primo 2450kv, given the similar vintage of the two motors. There has long been a debate over the differences between a wider stator and a taller stator and I was hoping to gain some insight here. Fortunately the kV of these motors are quite close, about as close as you can expect two different motors to be. The 2207 comes in a bit lower kV, so keep that in mind here. The 2207 edged out the 2306 by a tiny bit even with the lower kV, but the results were extremely close. Given the similar construction and tolerances on these motors it's an interesting comaparison worth some time in the data explorer. The R5 is a strong performer in the mid kV range, combining good response and torque with a reasonably light weight. In the R5, BrotherHobby continues to excel at balancing power and weight.
