Summary of Contest Events

For detailed information about each event, including official rules, please consult the Pink Book.

Event Objective Return Required Scoring Method Comments and Special Rules

  • all notes from Altitude event apply
  • depending on event, target altitude may be chosen by contest director, contestant, or selected randomly at the start of the contest
  • must be flown before any other altitude events
  • scored as relative error from target altitude
Cluster Altitude cluster several motors to reach highest altitude yes best single flight
  • all notes from Altitude event apply
