The high Kv option in the Hyptrain 2306 lineup.
The design decisions that went into the orginal Freestyle motor resulted in a solid balance of power, efficeincy, and smoothness, so I was curious to see how that would translate into other Kv. This higher Kv edition of the motor didn't disappoint on any of those fronts, retaining the smoothness power, but adding the extra response from the extra Kv. The measured Kv tested a bit higher than stated, coming in just over 2700kv. The results reflect this with even dual bladed 5" props easily clearing 1300g of thrust. For the power, efficiency is still solid for this motor, though it does loose some ground over its mid-Kv sibling at least at peak power. At equivalent thrust, efficiency is still essentially identical. Because of the high Kv and resulting maximum power consumption, this motor is going to do best on lower pitch, lighter loaded props, though up to 4.5 pitch triblades may be feasible with the right throttle management. The higher Kv on a lighter loaded prop here will give a very different throttle curve, even compared to the mid-Kv Hypetrain on a heavier prop that generates equivalent thrust, generating more snap, a bit more immediate response, and an overall sharper stick feel. Overall this is an intersting addition, adding some great functional diversity to the Hyptrain lineup.
