  • Length: 78.5"
  • Diameter: 4"
  • Weight: 76 oz.
  • Motor Mount: 54 mm.
  • Recommended motors: I - J
  • Recovery System: Parachute Not Provided (48" recommended)
  • CG: 57" from the nose tip.

This is a high-power kit.
You need to adjust CG, pick the parachute and retainer, therefore we suggest this kit for people with previous rocket building experience. Epoxy can cause an allergic reaction in some people. Adult supervision and wearing rubber gloves is recommended when working with epoxy.

This kit does not include an engine retention system. It is up to the builder to provide for motor retention. We recommend the 54mm diameter Aero Pack Engine Retainers (54L). They also give any rocket an extra professional-looking appearance. For dual-deployment - don't forget to pick 4" Altimeter Bay.
