The large stator motors recently have been an interesting battle between acheiving results through wider stators versus taller stators. This motor is one that takes the wider stator farther than any motor tested so far, pulling the width out to 25mm. Hoi motor has been experimenting with some new approaches, and this motor is pushing those. Hoi has been a part of the mini-quad world for some time, operating behind the scenes largely as an OEM manufacturer. This motor is solidly made, though the machining and finish isn't quite on par with some of the other motors to cross the bench. That is likely due to the experimental and rapidly changing designs of the Garila series of motors more than a statement of build quality. The parts of the build that matter a well executed. Probably the best feature is the lock nut used on the bottom of the shaft to retain the bell. Very nice addition, though it does end up impacting the space needed for the motor to fit on an arm. Some frames may need to drill out the center hole. The air gap on this motor is not quite as tight some of the other modern motors, but in this case that is likely an attempt to mitigate the heat retention from high voltage runs, a segement to which this motor is specifically targeted. I've been saying this a lot lately, but the only issue here for some will be the weight. Coming in just over 38g, this is not a light motor. Combined with the high KV, this puts this motor in a very narrow application point, specifically designed to go very fast at the expense of agility and current.
Results
The results here about what was expected given the design constraints of the motor. The KV tested a tad lower than the claimed 2750kv at just over 2650kv, which probably actually works in the motors favor. The current draw is fairly reasonable given the stator size and kV, but it is definitely not a motor designed for low current. Given the increased levels of unloading in the intended application though, it is managable given the target. The numbers here are impressive, with this motor falling just shy of the Cobra Chamption 2207 2600kv which was an insanely impressive motor. The only other motors that are really putting out more on 4S at this point are the 2408 and 2208 high KV motors from SunnySky and T-Motor, though those motors are not likely to handle high voltage as well. Overall, given the intended application of this motor, I think it meets its design goals very well.
