Location:
 The
contest will be held on a private
sod farm near Nowthen, MN. This location is just to
the east of Elk River, MN and to the northwest of the
Minneapolis/St. Paul metro area.
The location of this MASA launch site may be viewed on
Google maps.
For the GPS crowd, the field is at N45* 21.201', W93* 29.961'
The sod fields are typically surrounded on all
sides by crop fields - typically corn or soybeans. In
early June, the crops shouldn't be tall enough to pose too much
of a problem.
Directions:
From the north metro:
Take US Hwy 10 West, or US Hwy 169 North to where they
intersect. After crossing under US Hwy 10, the road that used
to be US 169 becomes Ferry Street N ( I believe also Co. Rd. 47).
Take this road to the north. This road also gets renamed to St.
Francis Blvd/ Co. Rd. 47 after going around two corners. Stay on Co
Rd 47 until you reach Nowthen Blvd NW/ Co. Rd. 5. Turn left onto
Nowthen Blvd NW/ Co. Rd. 5. Stay on Co. Rd. 5 to the town of Nowthen,
MN.

82. The farm is located on the driveway leading west with the sign
"Private Drive" located at the intersection of Tiger St NW
and 211th Ave NW.
Choice #2
Continue on Co. Rd. 5 through Nowthen, MN. Take a left turn on
211th Ave NW. This is a gravel road. The farm is
located on the driveway leading west with the sign " Private
Drive" located at the intersection of Tiger St NW and 211th Ave
NW.
From I-94:
Take the Elk River / Rogers exit. Take Hwy. 101 north. Hwy. 101 becomes US Hwy. 169.
Cross US Hwy. 10 and the Mississippi River. Continue on US
Hwy. 169 until you reach Main Street. Take a right onto Main
Street. Go two blocks, then take a left at the 4-way stop onto
Hwy 13. Follow Hwy 13 until you get to Co. Rd. 34/ 205th Ave
NW and take a right onto 205th Ave NW for 1.3 miles. Turn left
onto the gravel road at the "T" intersection.
The farm is located on the driveway leading west with the sign

The Basics:
-
Must follow model rocket safety code.
-
Rockets and motors must fall within the "model
rocket" definition.
-
Must use commercial motors that are "contest
approved".
-
Must use motors in the specified total impulse
range. (Example, in B streamer duration, you must use a B motor.
You are not allowed to use a motor smaller than B.)
-
Contestants are expected to help time the
duration flights of other contestants; you may not be an
official timer for your own flights. (Rule 15 has timing
details.) Each duration flight has two
timers; the flight score is the average of their two times.
-
Each of your contest rockets must have your name
and/or NAR number on it.
-
All rockets must be presented for a safety check
prior to flight; this includes a visual verification of the
motor used.
-
In most events, you have two official flights.
Normally, you have to return the entry to the officials after at
least one of your flights.
-
You cannot "spit" or eject a motor in flight
unless the ejected casing has an attached recovery device. (Rule
9.2)
-
Flights must be stable and safe, or else will be
DQ'ed by the RSO.
-
In duration events, you may not eject the motor,
or split the rocket into two or more unattached parts (exception
for boost gliders).
-
If you are using a reloadable motor, see section
4.2 for special rules.

-
All motors shall be ignited simultaneously.
Partial cluster ignition shall be deemed a qualified flight
unless DQ'ed for other safety reasons. Unignited motors carried
aloft shall be retained within
the model. An entry which fails to ignite all of its motors is
considered a qualified flight unless it is unsafe, experiences a
CATO, or the track is lost.

closed", the flight is considered unofficial and the contestant
may make an additional flight.
