GetFPV just sent out their notification that they have the RR HypeTrain motor in stock. I have about 20 packs through this motor and I have to say that it's a really excellent freestyle motor.
If you want to order this motor, move fast, because they will sell out quickly. And if you choose to use my affiliate link, of course I would appreciate that too.

My full video review will be out tomorrow. A teaser flight is linked above. It's one of my early shake-down flights so the goal is to test the motors' performance, not make an entertaining freestyle video. The flight is just after upgrading the copter to Betaflight 3.2 with minimal tuning, so if you see the tiniest bit of propwash, that's why.
I think you'll see that the motors are pretty powerful, although not as face-rippingly powerful as some racing motors. You'll be amazed to learn that full throttle punchouts were peaking around 85 amps! Flight times were closer to 3:00 or 3:30 than 2:00 or 2:30 like with some "ball-ripping" racing motors. Also notice how good the motor's response is on the sharp snappy rolls. Zero bounceback. Of course I was able to disable all the static filters in Betaflight and use just the dynamic notch while still coming down with cool motors.
I can't say that the Rotor Riot HypeTrain is the best freestyle motor on the market today, because there are too many great motors that I haven't tried. But I can say that after flying so many copters with battery-melting high-end racing motors, the HypeTrain is a breath of fresh air.
