Mission Requirements
Payload:
- The payload is a single, GoPro Hero 3 camera carried by a 1/18 or larger scale mini off road truck or buggy.
Air Mission:
- Take off and fly 15 flags. After passing the final upwind
pylon, the plane may fly a pass over, or land on the grass runway
deploying the ground vehicle and sensor.
Ground Mission:
- Navigate the ground course (manually or autonomously) to the objective.
Design
Constraints
Air Vehicle
- A single, internal combustion (IC) engine only.
Either of the following engines are allowed:
- O.S. 46 AX II ABL
- O.S. 55 AX ABL
- Methanol
/ Nitromethane fuel only. Contest provided Cool Power 15% or
equivalent
- No
Injections, fuel additives, or turbocharging
- All
propulsion power must come from the single IC engine.
- No
modifications may be made to the stock engine or the stock muffler other than removal of the conical baffle.
- Engines may be marked in an inconspicuous location during
inspection.
Teams must be willing to break down engines for post-contest
inspection / rules verification.
- Propeller
must be a commercially available, balanced propeller for gas/glow
engines only.
Propeller blades may be clipped in diameter.
- ROG (Rise off Ground) only. No launch assist of any type,
including hand launch. Teams may
use a
flight crew member to hold the airplane at the tail prior to
release if they desire, as long as the crew member is completely behind
the propeller arc. The runway is a smooth geotextile
material, and is 60 ft wide by 600 ft long. Three small seams
run along
the length of the runway spaced 15 ft. apart. There is also
an adjacent
grass runway of similar dimensions. Teams may use both
runways.
- Teams
may compete with multiple airframes, however the basic
airframe shape and size for each must be the same.
- No
part of the flight vehicle system may be jettisoned until after the air
mission is complete (after the last flag is crossed in the air).
Ground Vehicle
- Any 1/18 scale or larger, stock or modified mini off road truck or buggy is acceptable. For example
- Four-wheeled vehicle (4WD recommended)
- Electric powered. 2S Lipo, or 7-cell NiMH or NiCD maximum.
- Suspension: Off road. (Course is a combination of dirt (bare ground), mowed grass, and runway)
- Minimum wheelbase: 6.25 in
- Width (min tire edge to outer edge): 6.5 in
- Tire diameter (min): 2.125 in
- Tire width (min): 7/8 in
- Vehicle minimum dimensions must be met at all times.
Flight
Procedures and Scoring
Air Mission:
- Take off and fly to the safe distance designated course
entry (indicated by the safety judge)
- Time
starts after the pilot is cleared to enter the course, and the plane
passes the first turn line.
- Fly figure 8’s with all turns away from the pilot
as seen in the figure
below. Planes do not need to fly around a flag, they just must pass a
turn line in space.
- Each
team will provide two flight crew members to serve as turn indicators,
and will stand next to the Cut Judges. When a plane crosses
the
turn line, they will signal their caller by raising a flag.
Crew flaggers must not raise a flag prior to the airplane
crossing the turn line, or it will be considered a "cut."
- Cut Judges will use
a
sighting guide to
determine when a plane has passed a turn line, and if a flag has been
raised early, or if a plane has "cut" the turn. If a cut
occurs,
the judge will indicate a disqualification (DQ) for that
flight attempt by raising a flag. If a plane is DQ'ed, the
pilot should land as
soon as possible.
- After completing 15
flags, the aircraft must deploy the ground vehicle on the grass runway
(to the east of the main runway). This may be done by landing on
the grass runway,or deploying by other means such as dropping.
The only restriction is that the operation must be conducted over
or on the grass runway . If deployed by air drop, the aircraft may remain orbiting and then land at pilot/safety judge discretion.
Ground Mission
- Once deployed on the grass runway, the ground vehicle must navigate a course to the objective.
The course will be revealed to the teams at the event, but expect it to
consist of navigating around widely spaced cones, passing of sections
of mowed grass (1.5 inches or less), bare ground, and high speed runs along a length of the mat
runway. Expect the ground course total length to be between 2400 ft. and 3600 ft long.
- The
ground
mission may be done manually or autonomously. Autonomous
navigation results in a score bonus. To receive the bonus, all
operation of the ground vehicle after the vehicle begins moving, must
be done autonomously. Teams will be allowed to preview the course
for GPS coordinates if desired. Manual navigation must be done
with the driver in a predetermined location. The course will
allow the vehicle to be seen at all times, however the vehicle may be
as much as 400 ft away from the driver location at times. Teams
may not physically interact with the vehicle untill the mission is
complete.
- On
a part of the
ground course, a sign which is unreadable from the team location, will
be placed. To receive the mission score, the team must identify
the
contents of the sign using the camera, either via video feed, or
by downloading the recording after the mission. The sign content
may change each mission. The sign will be on a vertical board at
least 24 x 24 inches, and mounted so that the bottom edge is on the
ground. The image/lettering on the sign will be identifyable from
at least 50 ft away using the naked eye.
Score:
SCORE = Ttotal / Bonus (Low score wins)
Definitions:
T15 = Time from first flag to final flag in the air [seconds]
Ttotal = Total time from course entry to the completion of ground mission [seconds]
Scoring criteria and Bonus:
DQ | No Score Awarded |
Air mission complete, ground mission incomplete | Bonus = 0.25, Ttotal = T15 |
Completed mission using manual RC ground control | Bonus = 1 |
Completed mission using autonomous ground control | Bonus = 1.2 |
Safety Requirements
Safety
must be the number one priority of all contest participants. The
Speedfest organizers have gone to great lengths to keep the event safe
for participants and spectators. Please carefully note the
following:
- Contestants are expected to conduct themselves, and operate
their aircraft in accordance to the AMA Safety Code. (the following
link contains all AMA documents including the Safety Code: http://www.modelaircraft.org/documents.aspx)
- Every
person beyond the spectator line (including officials), must
wear a helmet approved by OSHA, DOT, ANSI, SNELL,NOCSAE or other
recognized organization that certifies safety equipment.
There is
a very wide variety of helmets that meet these criteria including;
skateboarding helmets, bicycle helmets,
construction hard-hats,
etc.
- Any flight crew member involved with starting the aircraft
engine
at any time (flightline or pits), Or holding the plane at runup/start,
must wear official safety
glasses, gloves (level-5 cut-resistant gloves are strongly recommended example), and hearing protection (foam earplugs are
sufficient)
- Teams
must make sure that people are standing clear of the plane of the
propeller in case of a blade failure. The safest
location is
behind the propeller. All individuals must be behind the
plane of
the propeller when running up the engine. Only the starter
should
be in front, however the throttle should not be advanced until the
starter is in a safe location.
- Flight
Crew: Required minimum flight crew is 4 members
(Pilot, Caller, and 2 Flagmen). Beyond that, the number and
makeup
of the flight crew is at the discretion of each team, however it may
consist of a maximum of 7 team members. Functions of flight crew
members may be combined if desired. All must verify current
AMA
membership at the event. Typical flight crew functions
include:
- Caller:
Stands by the pilot to call turns.
- Crew Flagmen:
Minimum
of two. Stand near turn marker judges to indicate turn line
passage
- Recovery:
(Optional)
Only flight crew and contest officials may
go recover aircraft
- Starter/Timer:
(Optional) Teams may have a member assist with
starting the engine on the
runway, and runup prior to start. The person may also serve
as a timer or additional flagman.
- Any level of
flight autonomy must be compliant with AMA rules (See http://www.modelaircraft.org/files/560.pdf)
- When a team
number is called for a flight, only flight crew may enter the field
beyond the spectator area.
- All aircraft
to be flown must go through an airworthiness inspection outlined below.
- For
teams not familiar with AMA contest airworthiness inspections, it is
recommended that an experienced RC pilot or AMA Contest Director assist
the team with an airworthiness inspection prior to travelling to the
Speedfest in order to reduce the chances of a delay requiring repairs
or modifications.
- All team
members, who attend the
event should be AMA members. It is the opinion of
the organizers that all
team members, must be committed to the AMA safety code
when designing, building, and flying, unmanned aircraft.
- Engines or
motors must not be started in the teams pit area. There will
be designated areas for engine runup and testing.
Pilots
- Speedfest is
not an event
appropriate for novice pilots. Teams should use
experienced
pilots
with a record of safety.
- Contest organizers will provide a pilot upon request.
Teams may not however request a specific pilot.
- Pilot instructions:
- Safety must be the primary responsibility of every pilot.
- If
there is some aspect of the airplane that the pilot deems unsafe, he
must ensure the team takes corrective action before flight.
- Pilots
must follow the instructions of the safety officer during flight.
If instructed to abort, or even sacrifice the airplane for
safety, the pilot must do so immediately without question.
- Pilots
must never allow the airplane to cross a line defined by the West edge
of the runway. If the line is crossed, power must be cut
immediately, and a turn made away from the spectators.
- Pilots
will be instructed how far to the east to fly patterns in order to
maintain safe distances from the spectators. India class uses
a
275 ft. setback from the spectator line. Alpha class uses a
675
ft. setback.
- During high speed flights in the pattern, Alpha
class pilots are requested to fly as low as they feel comfortable, to
provide an extra margin of safety for spectators.
General
Aircraft Requirements
Propeller
Metal
propellers are prohibited. Teams must
paint
the tips of their propellers (approximately 0.5 inches) on both sides,
white. This is to reduce chances of
injury. (Teams should balance their propellers after they are
painted.)
Engine
Mounting
The
engine should be securely attached to the mount, and the mount to the
airframe. Due to vibration, mounting bolts must use nylock
nuts,
or blue Loctite.
Radio
Gear:
Only
2.4 GHz spread
spectrum radios will be allowed. The
receiver battery must be a 5-cell NiCD or NiMH pack
and have an external switch. Teams must use a voltage monitor mounted permanently to the plane so that it may be seen at all times when the plane is on the ground. The monitor may be plugged into an open channel on the receiver, or connected to a "Y" at a point after the switch. The monitor must be ON when the required receiver switch is ON.
Range
Check and Fail-Safe:
Aircraft
receivers must be programmed with a fail safe system which will cut off
engine power if signal is lost or interrupted. Operation of
this
feature must be demonstrated. A standard range check must
also be
demonstrated using the procedure detailed in the transmitter manual.
Team
Name Lettering
Each
team will mark their airplane with their team name. Lettering
shall be clearly legible and sized at least 0.5 inches tall.
Lettering shall be on the top surface of the wing.
Abbreviations may be used. For example; "ZSU
Zebras" would
be acceptable.
Preflight
Airworthiness Inspection of Aircraft
Prior
to competition, all aircraft shall undergo a safety inspection.
Safety inspections will be conducted on a first come, first
served basis. Teams are encouraged to go through safety inspections on
the Friday afternoon of Speedfest so as to not miss any flight
opportunities.
The overall quality of construction must be considered safe and
airworthy. Safety inspectors will be checking the following:
- Push/pull
rods or cables and control horns, shall be installed in such a way that
they will not become disconnected in flight. Clevises must have a
"keeper mechanism." Adjustable control linkages that use set screws or
friction are NOT acceptable.
- Pushrods shall have only one threaded end that is free to
turn.
- Control surfaces shall be firm on the hinge line without
excessive play.
- Servos shall be mounted securely with little play.
- Any servo extensions used must have connections secured
with a servo lead lock
- All
screws holding the engine to the mount and the mount to the firewall
shall be in place and secure using nyloc nuts or Loctite.
- Spinner or prop nut used to secure propeller.
- Prop tips painted white last 0.5 inches of span.
- The
radio receiver and battery pack shall be secure, and surrounded by soft
foam rubber or other vibration-dampening material and adequately
protected against contamination by engine exhaust, raw fuel, or fuel
residue.
- Receiver battery check: 5-cell NiCD or NiMH, external
switch and Voltwatch. Voltwatch set to 6v setting.
- Wings, if removable, shall be securely attached to the
fuselage by some mechanical means such as bolts.
- The aircraft shall be structurally sound as well as free of structural damage
which may compromise safety.
- Range check / failsafe verification
- Proof
of prior flight. Teams must demonstrate proof of prior
flight.
This may be done using pictures or video evidence.
Repairs:
Any
aircraft that has been damaged after a safety inspection or has a known
history of problems shall not be permitted to fly until it has been
satisfactorily repaired and re-inspected.
Confirmation of class
rules:
Judges
will also confirm that all aircraft entered comply with the
Design Constraints. This will include inspection and
measurements of the airframe and engine for compliance.
Contest-Day
Information
- Each
team will be provided at least 3 flight attempt
opportunities. Maximum number of flight attempts depends on
several factors, and may be 7 or more. The best score of all
attempts will be
retained.
- Speedfest
objectives and scoring have been designed to minimize the effect of
weather conditions. Expect competition to continue unless
winds
are
above 30 mph sustained with cross, or if there is continuous rain.
If all teams are not provided with 3 flight attempt
opportunities, the rain date will be used.
- Speedfest is
a competition between teams.
There are no restrictions on repairs,
spare parts, replacement aircraft, etc. Repaired and
replacement
planes must still
conform to the rules for a particular class. If an aircraft
is
damaged to an extent that airworthiness may be questioned, and is to be
re-flown, the airplane must go through the airworthiness inspection
again. Also, if a replacement plane is used, it
must also go through the airworthiness inspection.
- Mandatory
Items to bring:
- Current
AMA membership cards for flight crews
- Proof of flight
- Helmets, safety glasses, hearing protection, and
gloves for Flight
Crew listed above.
- There
will be limited electrical service for individual teams. A
charging station will be
provided where teams may connect their charging equipment.
- A Rules
Committee will be formed for the purpose of resolving any rules
questions during the Speedfest event. The committee will
consist
of the contest director, a representative from one of the host
industries, and 3 volunteer team advisors (familiar with the Speedfest
rules) taken from the competing teams. Any controversial
rules
interpretations, protests, or conflicts, will be resolved by the
committee by a simple majority vote.
Registration
During
the designated time on the day of the event, flight crews must
register. Speedfest officials will then provide each with a
flight line pass. Registration consists of the following:
- Flight
crews must each show proof of current AMA membership
- Team
Flags and safety gear will be checked
- Flight
Crews, advisors, and mentors should report with their airplane to have
a team photo taken.
Flight Sequence
- Teams will
be assigned a queue number.
- Numbers will
be called in sequence from 1 to n
- Teams
will be fueled prior to entering the queue. Before receiving the fuel,
teams
must be able to confirm to a judge that their fuel tank is
empty.
- When
teams are called, they will need to go get their fuel in the hangar,
and have a receiver/transmitter voltage check. Failure of the
voltage check will result in DQ for that round.
- After fueling, teams will
move to the queue boxes
- Only
teams that are called to the flight line may pass the spectator line
and enter the course. They must wear the appropriate safety
gear.
- Alpha
Class: Each team has an X
minute window when called to the
flight
line. Within that window, the team must be able to
set up
their plane, compete, and clear the course. Failure to leave
the
course in the X minute
window will result in forfeiting the team’s
time slot in the next round. Continued violation will result
in
losing best score.
Optional Speedfest Team
Promotional Video Award
Speedfest
Teams that create promotional videos have the opportunity to
be
recognized at the event, and to receive awards. Videos can
promote: their team, airplane, university, country,
Speedfest, or any
combination of these in an entertaining and informative way.
Guidelines:
- Videos may

FAQ's
Can the airplane land on the runway but deploy the car
in the grass?
Yes. Under the Air Vehicle Design Constraints, the
rules state that “both runways may be used.”
However, the deployment of the ground vehicle must be done over the
grass runway.
Can the airplane begin the turn
before the flag?
Yes. However the team may NOT raise their turn
flag early. If the flag is raised early,
it will be considered DQ. If the plane
turns before the team flag is raised, the plane will have to turn back to pass
the flag before the flag is awarded.
How long is the “X” minute time
window?
That
will depend on the number of teams.
Expect the window to be no less than 8 minutes.
Do we need to tell the judges what the sign says
within the X minute time window?
No. You have until your next flight window to
identify the sign to the scorekeeper.
That is usually at least 1 hour.
At what point could team members
enter the flight zone to retrieve parts of the plane?
When
the safety judge gives the team clearance after the plane lands.
Do all items have to be retrieved
during the X minute window?
Yes. All items should
be recovered (unless it is beyond the fence) and the team completely off of the
field. Otherwise the team’s next flight
window is forfeited. For any item beyond
the fence, recovery is at judge’s discretion.
This may happen later during a flight break.
How will autonomous be verified?
After initiating the vehicle
motion, and switching to autonomous control, the driver must not have his hands
on the control stick or wheel. The flight
line judge will verify the car is not being driven.
Can we possibly have more information about the ground course?
Expect a ground course that is somewhat similar to a Speedfest air course, with the addition of a leg to identify the sign.
