This motor is the first of the Sonic Pro series from EgoDrift, who sent it over for testing.

Summary

I've been seeing a lot of chatter on social media about these EgoDrift Sonic Pro motors, so when the owner of EgoDrift contacted me about sending this to me to test, I was very curious. The fit and finish on these motors is impressive. The build quality and machining is top notch, and the physical design is just beautiful. I was very impressed with the overall build quality. Looking at the motor though, there were a couple areas of immediate concern. The biggest issue was that the air gap between the magnets and the stators is one of the largest I've seen on any of the modern motors. This makes the motor turn very smoothly, but comes at a significant performance cost. That combined with the relatively hefty weight of these motors, coming in right at 30g, and the weaker class (N50SH not N52H according to EgoDrift) were my only real issues. Other than that, these are some really gorgeous motors.

Test Results

NOTE: This motor is one of the first motors tested on the new power supply equipment. If you haven't already read the write-up on the MQTB Facebook page, it gives a good deal of information on the thought that went into these changes to the testing equipment.  As a result the numbers here aren't going to be 100% comparable to the other motors that have previously been tested, but they will still be close enough for valid comparison.  The numbers on the new tests will be a bit low on the lighter props compared to the older tests, evening out on the heavier loads.

My concerns on the airgap and magnet strength with this motor were spot on. The results here are significantly lower than most of the modern 2205 motors on the market, putting it at almost an exact performance tie with several other 2205 motors that have already been test here on MQTB that also use N50SH and have similar airgaps, so the results a pretty much exactly what were expected based on the specs. The EgoDrift manages to stay well ahead of the older generation motors, and is not likely to put much strain on the batteries at full throttle. Compared to the modern 2205 and 2206 motors that are in the same or lighter weight class, however it will definitely have a noticeable reduction in performance, both in response times and top end output. Whether or not that is critical will depend on the needs and desires of the pilot. For certain freestyle pilots it may not be a deal-breaker, but if top speed is a priority this motor may not be the best selection. Given the excellent quality of the motor, I hope to see a more performance driven option from EgoDrift that will broaden their offerings to a more varied demographic of pilots.
