Specifications - Division 3 (Payload Drop)
Payload drop
Aircraft shall drop a ping pong ball
Ball can be carried anywhere on aircraft
Ball shall land between 40ft and 60ft from launch point
Hitting the target adds 50% to your total flight distance
(which can be combined with the 50% from hitting a “field goal”)
Payload Drop Zone
60ft
20ft
40ftSlide10
Specifications - Division 3 (Payload Drop)
Glide path
Aircraft shall have a glide ratio performance of 12
Goal post located at 60ft from launch point
Horizontal bar at 10ft
Vertical bars located 10ft either side if centerline
Hitting
a “field goal”
adds 50% to your total
flight distance
(which can be combined with the 50% from hitting the target)
A “field goal” is when a plane flies between the verticals and over the horizontal, even if it hits the bars.Slide11
Materials - Division 1
All materials must be similar to those in the provided kit and approved by BoeingAny balsa or bass wood is acceptable
Polystyrene foam and
heat-sensitive plastic film that shrinks (brands: 'UltraCote' and ‘Top Flite Monokote’) is also permittedPlease use extreme caution with the heat wrap. Parental or teacher guidance is required.
All joints, on the aircraft, shall be constructed with glue, epoxy, tape, thread (as in stitching), bubble gum, Velcro, etc.
Glue: Cyanoacrilate or CA+ Super Glue works great with Balsa wood, not so much with polystyrene
Rubber bands or magnets are permitted to secure wing to fuselage
All weight and balancing shall be accomplished by the concentrations of glue, clay, balsa/bass wood, or coins
Control surfaces and hinge construction can be made from bass or balsa wood, any kind of tape (aluminum tape recommended for hinge), or aluminum foil.
Kits will be provided to teams with a basic set of materials
Additional material as specified above permitted
Not all of the materials in the kit must be used
Aircraft are allowed to be painted
No carbon fiber or 3D Printed parts allowedSlide12

Awards: Performance Success Judging
Maximum Time AloftThe duration of each flight will be measured from the time the craft leaves the contestant's hand to the moment the craft touches the ground
If an aircraft hits a wall, the time will end
Longest Ground Distance
The longest distance will be measured from the competition start point to the location of the initial touchdown of the aircraft
Any aircraft that hit the opposite wall will be measured from the point on the wall and traced down to the ground for measuring purposes
Due to judging constraints it will not be taken into consideration how high up the wall the aircrafts hit but rather if the aircraft hits the wall at all
Adjustments due to the number of balls (
Div
2) or hitting the target and “field goal” (
Div
3) are made to
the total flight distance for a
single flight
for that teamStraightest Flight Path The flight resulting in the lowest angle, as measured between a straight line extending from the start point and the straight line from the start point to the location of initial touchdown, specifically for the same flight on which the longest distance is recorded.Any aircraft that hits the opposite wall will be measured from the point on the wall and traced down to the ground for measuring purposes
Flight must exceed 20 feet from launch to be scored for straightest flightSlide15
Awards: Performance Success Judging
Highest Quality of FlightJudges will be assigned to determine the smoothest and straightest-in-air quality of flight
Overall Division Champion
An average of the two
best flights will
be determined
and added to the Total Design Review score
Each flight score is reduced by the distance off center
The
team with the highest score will be deemed the winner of
the Challenge DivisionSlide16
Awards: Performance Success Judging
In this example, Flight A would win straightest path and Flight B would win longest flight path. Flight C would not have been scored for straightest path.

Awards: Fabrication Success Judging
Most Creative AppearanceTeams will be judged on external appearance of aircraft Most Creative Engineering
Teams will be judged on their engineering design process and its results on the end product
These awards do not roll up in the final overall scoreSlide18
Other Judging Information
Each contestant will be allowed three official flights with one team mate launching the aircraft.If for some reason the aircraft is damaged during the impact of a first or second run, your team will be allowed to fix any problems during the time between flights. If you are unable to fly at the time of your second flight, then the second flight will be forfeited.
You will still be given a third flight opportunity if your craft is ready at that time.
There will be no duplicate prizes. Ties will be determined by a panel of judges.
Once flight test order is established, the order will remain the same for the remainder of the fly-off.
Once every team has had the chance to attempt their first flight, the next round will commence immediately thereafter following the same order.Slide19
