INTENT OF RULES

The idea is

1) Avoid the need for eagle vision by

• limiting the height of powered climb

• shorter flights to reduce need for high thermal climbs

2) Wider range of skills -- points for

a) takeoff

c) precision time

3) Competitors vote on their preferences for the next contest.

4) More spectator appeal.
