Tested KV:2500kv

This motor is a bit of a throw-back to the SE2205 that was popular last year.  The 2300kv motor was a strong performer against the motors of it's day, though it fades a bit by current standards.  This higher kV version pushes the performance up enough to make it still relevant for certain applications in today's market. My primary complaint about this motor is the weight, coming in at just under 30g it is a bit heavy for a 2205 motor, pitting it against even 2207 motors in the same weight class.

Results

Some interesting results here with this motor, comparing a design that is a bit older against some of the newer motors out.  This motor pulls significantly ahead of its lower kV sibling and the other motors in that class, easily clearing 1250g at 29A sustained on the 5x4x3, essentially matching the Tattu 2305 2450kv motor in power and efficiency.  The lower torque of the design starts showing on the heavier 5" props, where the windings started to heat up a bit.  The most obvious result of the lower torque here is that the performance difference between the mid-weight props like the 5x4x3 and Cyclone 5045 and the heavy 5" props like the 5x4x4 and Cyclone 5046 is fairly minimal, showing only about 50-70g gain, and minimal current increase, but a significant drop in transition speeds. As a result , I would say the best props for this motor will be the mid-weight props where the motor can take advantage of the higher kV without getting bogged down by the heavier props for minimal gains.
