Cirrus - This high velocity, 38mm minimum diameter dart is capable of extremely high altitudes with relatively small motors. Perfect for "H" and "I" class altitude attempts. The Cirrus Dart is a specialized super-high-performance kit and should only be used by experienced high power fliers. The Cirrus comes with: Pre-slotted phenolic airframe Piston ejection system G-10 fiberglass fins Ultra-light nylon parachute Pre-weighted solid nosecone Pre-cut 6 oz fiberglass reinforcement cloth 7.5" Payload Bay Explicit instructions. Don`t let its small size fool you, this is NOT a "model" rocket! In fact this rocket can attain higher altitudes than a 4 inch diameter rocket using a "K" motor; and at a small fraction of the cost. Think about it... If recording the highest altitude is your goal, why would you put a 2-ounce altimeter measuring 1.5" x 4" in a 20 pound behemoth to attain a lower altitude? See the Motor Specifications Chart in the Spec Sheet section of PMLâ€™s website for performance information. This is not a "Skill Level 1" rocket kit. To keep a high velocity, minimum diameter rocket like this together during flight, several important construction steps must be strictly adhered to. But don`t worry, everything you need (except for adhesives and paint) is supplied with the kit. Very explicit, step-by-step instructions are supplied as well. 20 minute Finish Cure Epoxy (EPY-FINISHING) will be required in addition to your regular 5 minute epoxy (EPY-5MIN). A HAMR motor retainer is not recommended for the Cirrus kit as it will disturb the airflow by projecting beyond the sides of the airframe, negatively impacting the purpose of the Cirrus, low drag and high altitude.
