Well pulled the trigger on this kit today. Spec it out with the 100a castle esc, going to run the rclander 90mm 12 blade with metal surround with a 1050kv rclander motor. Thrust spec is 8.25lbs. Will be running this bad boy on 8s 4000 40c. Should haul butt thrust to weight is 1.65:1 on paper and she will have that rockin turbine sound!!!
