Helicopters

Helicopter Duration is a 2010 National Tournament Trial Event where you have to build a rubber-powered helicopter that can fly for as long as possible.

=Construction Process= A simple design you can build is the Wright Bat Flier.

It is important to emphasize the hardest part, however, is that you cannot use commercially available propellers, as previously stated.

=Scoring= Only the better flight (out of the 2) will be scored.

Bonuses
State: If 2 rotors are used, 15% of the flight time is added to the final score.

National: If 1 rotor is used, 30% of the flight time is added to the final score.
