 NOTE: The webserver has an issue and signup calendar does not work right now.
The weather looks good for tomorrow, the grass may be wet from a little rain over night. It should be sunny with temperatures in the low 70s.
 
There will be a 8-11 mile wind (18 mile gusts) from the north-west blowing towards the south-east. That means the rockets will drift towards the high power lines east of the field.  Please plan accordingly and limit altitude, use dual deploy and make sure to not accidentally open the main at high altitude. Use trackers!
 
We will run the "driftcast" model tonight and send out another email with the predicted landing zones.
 
William Schmiedlin will be the Prefect for this launch.
 
On-Field Provisions: 
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.
 
L- Certification Motors:
The club has bought a few H-size motors and has them available for new members who would like to fly their L1 certification. See us at the club table if you need one for your flight. We have 2 each of:
38 mm :  Aerotech H283-15A Super Thunder and Aerotech H219T-14A Blue
29 mm:  Aerotech H115DM-14A Dark Matter
If you are new to the club and not aware, these are a few points 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.
  • Arm all pyro controlling 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!  

Rocket Crashes are Scary for EVERYONE!

There were several rockets that came back to the flight line at the last launch.  It is everyone's responsibility to keep your eyes on the sky!  If you hear the horn and/or a heads-up call it is not just for fun, it's a signal that we have a rocket that is heading towards the flight line.  Looking up is not optional!

Stop, Look up, and Get out of the way!!! 

If you are unsure of your rocket's recovery setup, please ask!  The club is full of great people always willing to help.  A second set of eyes (even for experienced fliers) is not a bad thing.  We have all had bad things happen we can't explain, but we need to make sure every attempt has been made to have a safe recovery.
