We are asked all the time what parachutes make good drogue parachutes, so here ya go. The smaller Classic Elliptical chutes make good drogue parachutes for our large Iris Chutes.  Or just use these in your smaller rockets. These are also good choices for pilot parachutes to help drag the deployment bag off the large main parachute.

As a good rule of thumb the Drogue or Pilot chute is 1/4 to 1/5 the diameter of your main chute.  When using Rocksim or other calculator the descent rate shown will be higher than you will get in real life because of the drag of the airframe.  So choose a size smaller to actually get the descent rate the simulation tells you.
