This year the challenge is to build and fly a rocket using helicopter recovery, the winner achieving the longest flight duration from take-off to touch down.
The rules are simple:
- Recovery must be solely by auto rotation around the vertical axis.
- Maximum motor size A.
- Rocket may not separate any piece during flight.
- More than one model may be flown multiple times, subject to time constraints on the day.
- UPDATE 19/9/21 Phil Charlesworth wins with a time of 59.44 seconds
