Garila X2506 2600kv

Tested KV:2550kv
Weight:37.8g
Stator W:25mm
Stator H:6mm
Garila has made a name for themselves by approaching motor design in a bit of a different direction, opting for stator width over height, and pushing the limits of stator size for mini-quads rather than focusing on internal optimizations such as magnet strength and air-gap reduction. This X series is a followup of the earlier tested J2506, which makes some small internal improvements, but is otherwise essentially identical.  The weight seems to also be a tad lower, coming in about half a gram less than the J series with equivalent wire length.  There doesn't appear to be any visible differences between motors, so my assumption is that the changes are largely related to the choice of magnets.

Results

This motor is a bit lower Kv than the previously tested Garila, stating 2600kv on the bell and testing right at 2550kv.  The internal improvements for the X series seem to have boosted performance a tad, bring the results of the 2600kv here to just shy of the J series 2750kv.  The 50kv difference between the motors is most obvious on the lighter props where the higher Kv J series pulls ahead, though the X series narrows the gap on the heavier props.  The X series line from Garila is still what I would consider a conservative design however, relying primarily on the stator size for power and response.  For instance there are a number of smaller motors that are more performance focused and give faster changes in RPM with more agressive maximum output for the equivalent Kv, but that often comes at a current consumption cost. There are definitely gains to the Garila approach. They run much cooler than other motors in the same thrust range.  The better temperature handling, larger air gap, and decreased field strength will improve handling of higher voltages, even at higher Kv.  Even though this approach is fairly unusual in today's motor market, this combination still creates a compelling result for certain applications, though the weight remains a barrier for some.  I will be interested to see further progression of this design and exploration of its unique possibilities.
