All you who have built a Bensen or Brock Gyro

[skyguynca]

Many years ago I built a KB2 with a 90hp MAC, barely came in legally under 254 lbs. One thing I did not do and wished I had.....I am looking for the empty airframe weight of either a Bensen or Brock airframe but does not include the rotorblades, engine or instruments. Just the basic airframe with or without wheels.

Thanks
