This kit was the very first in a series of high-performance rocket kits using our CPR (Close Proximity Recovery) system!
The Sudden Rush rocket kit is being retired. There are a very small number of kits still available, so if you want one, please order it ASAP. Thank you.
The Sudden Rush has been flown many times at HPR launches nationwide and has a proven track record of successful Close Proximity Recoveries in windy conditions! This popular rocket includes the Kwik-Switch motor mount, 0.093" thick G-10 fins, a tail cone and of course, the CPR3000 Dual-Deployment Recovery System.

The SUDDEN RUSH is the first in the CPR series and is an overall great and versatile kit for Level 1 and 2 flights. This rocket stands 65" tall, is 3.1" in diameter and has a 3 fin design. This rocket comes standard with a 54/38/29mm Kwik-Switch motor mount and can fly on H thru J motors. At ~61 oz., the 48" main & 18" drogue parachute is sized right for the stock kit to make a safe landing under most field conditions. This kit comes standard with our exclusive Linear Rail Lugs for use with 80/20 brand launch rails. The stock airframe is ideal for flights up to approx. 0.85 Mach.
Below you will find a number of upgrade options. Upgrading the parachute size may be necessary if you intend to build heavy or have a hard landing surface (i.e. gravel, pavement, desert playa, etc.). Some motors will accelerate this rocket to transonic or even supersonic velocities. Under these conditions, this kit may require the fin upgrade, foam encapsulation of the fin root, as well as other advanced construction skills.
It is prudent to sim your kit/motor combination using the actual weight of your finished model to determine max velocity, altitude, ejection delay, etc. This will allow you to make an informed decision when selecting a suitable motor for your rocket. Please download and read the PML FAQ and/or consult with a NAR or Tripoli certified member to ensure your flights are fun and safe.
