I also flew Alex Varv's Cors-Air Kangook with the Black Devil engine and I agree with Eric Dufour's and Jeff Goin's assessments:
1. Almost zero torque, amazing for such a powerful motor
2. Excellent weight shift, maybe the best for an engine that size
3. A low price tag
Alex's system provides a high power no torque paramotor for experienced pilots who want power, super response and smooth handling.
Thank you Alex for allowing me to test out your new innovative system, and for continuing to provide excellent support for the Corsair engines!
