The field is at N45* 21.201', W93* 29.961'

The sod fields are surrounded on all sides by crop fields.  It's all CORN this year.  #sigh#

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 use 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. ( see map )  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. ( see map)  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 past the Elk River/ Rogers VFW launch site. Hwy. 101 becomes US Hwy. 169. Cross US Hwy. 10 and the Mississippi River.  Continue on US Hwy. 169 until Co. Rd. 33. Turn right onto Co. Rd. 33. Continue driving on Co. Rd. 33, until you reach Twin Lakes Road. Turn right unto Twin Lakes Road. Continue on Twin Lakes Road to Co. Rd. 34/ 205th Ave NW. Turn left onto 205th Ave NW for 1.3 miles. Turn left onto a gravel road (the Tiger St. NW sign fell off the post).  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.

(Slightly less annoying route - from 169, 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 and take a right.  Rest of directions are as above.)

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 A streamer duration, you must use an A motor. You are not allowed to use a motor smaller than A.)

  • 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.

Here are quickie summaries of the contest events.  For the full rules, follow the links!

A Helicopter Duration <http://www.nar.org/pinkbook/32_HD.html> (WF 20)

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

  • "A" 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.

1/2A Boost Glide Duration <http://www.nar.org/pinkbook/36_BG.html> (WF 17)

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

  • "1/2A" 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.

A Streamer Duration <http://www.nar.org/pinkbook/31_SD.html> (WF 8)

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

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

C Rocket Glider Duration <http://www.nar.org/pinkbook/37_RG.html> (WF 22)

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

  • "C" motor class. Entry may NOT separate into multiple pieces.  Motor casing must be retained within glider.  Entry must return to the ground in stable, gliding flight supported by aerodynamic lifting surfaces which sustain it against gravity.  Radio Control is permitted.

  • Any entry that descends with parachute and/or streamer recovery device(s) attached shall be disqualified.

  • Minimum rocket length of 75 cm.  Maximum rocket length of 150 cm. (measured from tip of the nose cone to end of the motor nozzle)

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