• PyroDrone CM2206 2350kv

This is an older motor PyroFlip sent over for comparison testing. It's primary point of interest is that it is one of the lightest 2206 motors ever to hit the bench at 26g.

Summary

This motor was put on the bench primarily as a point of comparison to the more recent modern motors that have been tested recently.  It is an older design that PyroFlip with older magnets and a fairly large air gap. It's primary claim to fame though is a stunningly low 26g weight, putting it well below most of the current 2205 motors on the market. The fact that it hits such a low weight point at a 2206 stator size makes it interesting even against some of the more modern motors.  The build quality is solid, though the machining and anodization is not the cleanest I've seen. The tolerances and smoothness of the motor is excellent however, so it seems any issues are simply cosmetic, not with the actual construction of the motor.

Test Results

The results here were about what I expected given the vintage and construction of the motor.  If we compare it against the comon motors of time when this motor came out, it would be absolutely killer, easily destroying the Cobra 2205 2300kv that was king at the time while matching it in weight. By modern standards the results fall a good deal short, coming in shy of even the mid-range 2205s of modern design.  The closest comparison with this motor are the N50SH based 2205 motors, where it essentially matches thrust, with a bit superior response times thanks to the taller stators.  On an interesting note, it actually beats out the ever popular Lumenier RX2206 2350kv motor by a decent bit, while being a couple grams lighter.  While the results here aren't super impressive by modern standards, the weight of the motor makes up for that significantly, making this motor still an interesting point of comparison.
