The Hornet features a 45 HP Kubota diesel engine, top drive assembly with a hollow/floating spindle and a modular design. The rig can be broken down into modules that weigh less than 1200 lbs. and are compact enough to fit into a small fixed-wing aircraft.


  • Lightweight modular design
  • No module over 1250 lbs.
  • Ideal for early-stage exploration
  • Available booster package for deeper holes
