A contest range with central controller and pads will be set up.
A separate sport range will also be set up.
The sport range will be "misfire alley" - bring your own pad & controller.  Our waiver allows flights to 4,500 feet AGL.  Based on field size and distances from occupied buildings, the maximum practical flight altitude is 4,000 ft agl.  Field size supports up to a J motor.

Sunday
A contest range with central controller and pads will be set up.
A separate sport range will also be set up.
The sport range will be "misfire alley" - bring your own pad & controller.  The waiver will NOT be active on Sunday.  This limits sport flights to < 3.3 lb and no more than 125 grams of propellant.

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.

Choice #1

On the north edge of town turn left onto 201st Ave NW/ Co. Rd. 65.  Turn right onto Tiger St. NW/ Co. Rd. 82. This road switches to a gravel road after going by 205th Ave NW/ Co. Rd. 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 " Private Drive" located at the intersection of Tiger St NW and 211th Ave NW.

For the full applicable rules, see the NAR Model Rocket Sporting Code.  http://www.nar.org/pinkbook/

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.

 

B Streamer Duration <http://www.nar.org/pinkbook/31_SD.html> (WF 9)

  • Goal - achieve the longest flight duration time(s).

  • "B" motor class. Single-staged rockets with single streamer recovery.

  • Streamer must have L:W ratio of 5:1 or greater with minimum area of 100 cm2. Streamer connected to model with only a single line.

  • Two flights (one returned). Score is sum of durations from the qualified flights.

1/2A Parachute Duration <http://www.nar.org/pinkbook/30_PD.html> (WF 7)

  • Goal - achieve the longest flight duration time(s).

  • "1/2A" motor class. Single-staged rockets with parachute recovery.

  • Two flights (one returned). Score is sum of durations from the qualified flights.

1/4A Boost Glide Duration <http://www.nar.org/pinkbook/36_BG.html> (WF 18)

  • Goal - achieve the longest flight duration time(s).

  • "1/4A" motor class. One portion of entry must return to the ground in stable, gliding flight. Entry may separate into multiple pieces; only the glider is timed.

  • Gliding surfaces may not be made of flexible materials (plastic, etc).

  • Two flights (one returned). Score is sum of durations from the qualified flights.

D Helicopter Duration <http://www.nar.org/pinkbook/32_HD.html> (WF 23)

  • Goal - achieve the longest flight duration time(s) using an autorotating recovery system.

  • "D" motor class. Single-staged rockets. Must be decelerated during descent by an autorotating recovery device. The resulting autorotation must be around the vertical axis.

  • Two flights (one returned). Score is sum of durations from the qualified flights.

A Cluster Altitude <http://www.nar.org/pinkbook/23_CA.html> (WF 16)

  • Goal - achieve the highest altitude.

  • "A" motor class. Single-staged rockets. Rocket MUST contain FOUR (4) "A" motors.

  • All motor cases must be retained in the model. Following an official flight, a contestant must present his/her model as recovered to a contest official for verification of motor casing retention or the flight will be DQ'ed.

  • 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.

  • Use of tracking powder is highly recommended.

  • In the case of "track lost" or "track not closed", the flight is considered unofficial and the contestant may make an additional flight.

  • Two flights (both must be returned). Score is the higher altitude of the qualified flights.
