5th Annual MASA Summer Regional Contest
June 15 and 16, 2013

NOTE THE DATE CHANGE! 
"The Saturday morning forecast is calling for a 40% chance of thunderstorms,
mist, and a 400' ceiling in the morning so check the skies & email (and this web page) before
heading to the field.
The land owner has given us his OK for the launch, but, if we get more than
1/2" of rain Friday night, he wants us to delay the start time to let things
dry off a little bit.
The weather is looking good for Saturday afternoon through Sunday so we
just need to get through Saturday morning."

Nowthen, Minnesota
(NW Minneapolis/St Paul metro area)

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.

For the GPS crowd, the field is at N45* 21.201', W93* 29.961'

The sod fields are surrounded on all sides by crop fields - typically corn or soybeans.  In early June, the crops won'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 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.)

Nearby Hotels:

As a courtesy to those competitors coming in from out-of-town, here are the names of several hotels within about 5 miles of the contest field.

Additional hotels are located at the junction of I-94 and Highway 101 (about 10 miles from the contest field).

Overnight camping is NOT allowed at the launch site.  There are some campgrounds in the general area.

Food:

There are a number of restaurants and stores in Elk River along Highway 169, about 4-5 miles from the contest field.  [Walmart is about 4.5 miles away.]  There are two restaurants in the small town of Nowthen, about 3 miles from the contest field.  There is also a large gas station and convenience store ("Bill's") in Nowthen at the intersection of Hwy 22 and Hwy 5.  [google maps link]

Other:

There will be a "porta potty" on site.

Jon Stenberg has volunteered to buy pizza for the registered competitors.  Thanks, Jon!

See you there!


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

Also, for lots of great information, see the new NAR Competition Guide, https://sites.google.com/site/xnarcompetition/home

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.

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

A Streamer Duration <http://www.nar.org/pinkbook/31_SD.html and https://sites.google.com/site/xnarcompetition/duration-events/streamer-duration> (WF 8)

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

  • "A" 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 Boost Glide Duration <http://www.nar.org/pinkbook/36_BG.html and https://sites.google.com/site/xnarcompetition/duration-events/boost-glide-duration> (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 Rocket Glider Duration Multi-Round <http://www.nar.org/pinkbook/37_RG.html and https://sites.google.com/site/xnarcompetition/duration-events/rocket-glider-duration> (WF 24)

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

  • "A" 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.

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

  • Multi-Round Max is 120 seconds.

  • Each contestant is initially allowed three official flights in a multi-round event.  A contestant may enter no more than two models for making all official flights including any necessary additional flights.

  • The official duration of each flight shall be calculated as follows: if the duration achieved exceeds the maximum time limit defined for that flight, the entry shall be awarded the maximum time limit; otherwise the entry shall be awarded its achieved duration in seconds. Timers may stop timing the flight after it has achieved the maximum time.

  • Multi-round events shall be scored as follows: the official durations achieved by the contestant on the initial three official flights in the event shall be summed. If there is no tie for first place, then the contestant achieving the highest score is the winner. If there is a tie, contenders for first place shall be given the opportunity to make additional official flights (flyoffs) to determine the winner.

1/4A Helicopter Duration <http://www.nar.org/pinkbook/32_HD.html and https://sites.google.com/site/xnarcompetition/duration-events/helicopter-duration> (WF 20)

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

  • "1/4A" motor class. Single-staged rockets. Must be decelerated during descent by an autorotating recovery device. The resulting autorotation must be around the vertical axis.  Rocket must make at least one full rotation around its roll axis during recovery.

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

1/8A Parachute Duration Multi-Round <http://www.nar.org/pinkbook/30_PD.html and https://sites.google.com/site/xnarcompetition/duration-events/parachute-duration> (WF 11)

  • The official duration of each flight shall be calculated as follows: if the duration achieved exceeds the maximum time limit defined for that flight, the entry shall be awarded the maximum time limit; otherwise the entry shall be awarded its achieved duration in seconds. Timers may stop timing the flight after it has achieved the maximum time.

  • Multi-round events shall be scored as follows: the official durations achieved by the contestant on the initial three official flights in the event shall be summed. If there is no tie for first place, then the contestant achieving the highest score is the winner. If there is a tie, contenders for first place shall be given the opportunity to make additional official flights (flyoffs) to determine the winner.
