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.
