Subject: September 2025 - URGENT Launch Update Announcement
From: Tripoli Minnesota


TRIPOLI MINNESOTA - PREFECTURE #45 
I have been informed by the FAA that we won't be able to hold our night launch this month.  The paperwork is still being processed, and all of the departmental signatures aren't fully collected.  Please keep your fingers crossed for an October reschedule. 
September 13th, 2025
DAY Launch ONLY
North Branch, MN - Central Turf Farms
  • Setup starts at 9:00 am
  • Flying starts about 10:00 am
  • Tear-down 4:30-6:00 pm
Please stay for tear-down and help repack the trailer.
Waiver to 20,000ft weather dependent.
The 5-day away weather looks decent for the September launch!
The current forecasted temperature for the launch should be in the upper 70's  to low 80's during the day.  Possible lower cloud ceiling, and some wind gusts.
 
The website has been updated...  WE have a working volunteer page!

Official Club Correspondence:
If you are a club member, please occasionally login to the Tripoli Minnesota Website (www.tripolimn.org). We are adding a members only discussion forum and a members only events page.  
If you are new to the club and not aware, I would like to point out a few rules of etiquette:
  • This is a working farm.  Please be respectful of the land, roads, and fields.  The turf is a cash crop.  Let's treat it as such.
  • All vehicles should drive slowly on the roads.  The road is dirt & clay, so if its wet, it DOES get sloppy.
  • When you get to the field, please back into a spot.  We want to keep engine fluid drips as close to the road as possible (farm's request).
  • If there are freshly planted fields that your rocket lands in, only send one person to retrieve it.  Less tracks = less crop damage.
  • The fields are surrounded by drainage ditches.  They are deep!  If you need to cross one, find the spot where the sprinkler crosses.
Rocketry Rules Refresher:  
  • Always make sure pyro charges are disabled until at the pad.
  • With all mid power and high power rockets: DO NOT install igniters until at the pad.  Low power rockets are the ONLY exception.
  • Keep the rocket pointed in a safe direction on your way to the RSO table, and towards the pads once at the table.
  • It's good practice to arm all electronics at the pad, prior to installing the igniter.  
  • Never, ever, ever... catch a rocket.
  • Do not retrieve another person's rocket without consent or knowledge of the flyer.
    •  Ejection charges may still be intact, or electronics may need attention prior to moving the rocket.
    •  It makes it very hard to find a rocket that has already been retrieved.  Note the location and call it in.
  • Only HP certified fliers are allowed at the pads (sorry kiddos).
  • If you hear the air horn, LOOK UP!  
On-Field Provisions:
Off We Go Rocketry - Gary will be attending the launch with a large assortment of rocket motors and rocketry related supplies.
Food - Brian's Brats
Rest Room - We will have a handicap accessible porta potty at the field.
Trash - There are usually two trash cans located near the LCO table.  Please use them.
