A few notes...

Due to the late sunset at this time of year and the proximity of a nearby residential neighborhood, we will have approximately 1 hour for twi-light / night flying, before we need to conclude, so when considering how many flights you'd like to make, please allow for launch and recovery time per rocket. Recovery will take longer in the dark. Please plan on recovering each rocket before you make another flight, probably at 5 -10 minutes per flight.

To keep things simple for the evening, we ask that everyone planning to fly please make a special effort to pre-register all of the rockets you plan to fly by Friday August 15th if at all possible. This will let us know exactly how many flights there will be, and so that day we can RSO the rockets well in advance of the night launch.

Please use this space on the message to post all of your planned flights - or - you may email your list to me: randyolb@hotmail.com

Rockets may carry lights of any color and as bright as you care to make them, but please note that in order to protect everyone's night vision, just before and during the night launch, we ask that all lighting equipment used for prepping and recovery be kept to a minimum and low wattage.

We want to have enough light to function but not enough to disrupt the over all theme of the launch and if at all possible, lights should be shielded to project light downward and turned off when they are not needed. We will be discussing ways to light your pads, rockets and prepping area on the BRB message board shortly.

Where and if possible, please use a green, yellow or red lens flashlight. Red, yellow and green lens material can be found at most hobby stores, Walmart, etc. or colored packing tape can be used over a regular flashlight lens to get the same effect.

*If anyone has to use a regular white light of any kind, please use one of very low intensity and only when necessary.

*No high intensity lighting, please! Mag Lights or similar flashlights are not recommended. This will not be a good time to show off your "Tim The Tool Man Taylor" 50k generator or 60 gigawatt Christmas lights.

Please keep in mind our proximity to the airport and the nearby neighborhood. We would also ask that everyone (especially the kids) please refrain from "spot lighting" other flyers, spectators, rockets in flight, passing planes - and the neighboring houses, which is actually against the law.

After the night launch is over, regular flashlights or car headlights may be used for packing up.

All rockets must be submitted to a Nite Flight RSO before they can be flown. No exceptions. In order to prevent a log jam we suggest all night flight rockets be prepped and submitted to a RSO for approval by 6:00pm or sooner.

It is strongly suggested that you have your night flight rockets RSO'ed as soon as possible, just in case you need to make adjustments while there is daylight and time to make them. If your rocket is new or has never been modified for night flights please plan to make at least 1 daylight flight with it to make sure things will go well that evening.

It will be much easier to breakdown your camp while we still have some daylight. To that end we suggest that well before dark we all pack up anything that is not necessary for night flying.

Recently I talked with SEARS President Greg Lane about how 572 managed their night launches and he sent me some very good ideas, with several links to some photos and a video of what he has tried with great success. Below are Greg's tips...

NOTE: To view the links please open the attached .pdf.
From SEARS 572 President Greg Lane
 
Light sticks are one way go.  LEDs can be put inside a nose cone and will shine thru in some cases. If you have time for electronics it is a matter of looking around and finding items to adapt. The LED pendants are easy to tape on most rockets.
 
It is best to have minimum equipment out because packup is hard after dark. Note you can use light sticks on dowels to mark a path to your pad.
 
I have had some experience with blinking LED pendants. Here are some pictures of how I was using the pendants. This is a source for them I used in the past. I have ordered some replacements from ebay
 
I have taped my  LEDs to my cluster saucer. This was emergency mode. See on pad video andlaunch video
 
I also found some LEDs at hobby lobby and put them in a Quest Courier nosecone. Oh yes, and I have ordered some EL wire from these folks and I am planing to use it on a Mean Machine.

Count us in...!!!

We haven't decided what we might fly... yet.  We're looking for a strobe system at the right voltage... no luck yet. 
I know George has some great ideas... might go that route... we still have a little time.

George asked me to post this as he is temporarily off line.


From George Gassaway...

I’ve uploaded a video showing the LED Finger Light and how well it lights up an unpainted Estes long BT-60 nose cone: http://homepage.mac.com/georgegassaway/LED_Nose_Cone.mov   

This video is only 1.3 megs so it would be worth the wait for the download.

I only taped the light in place for the test, after making a 1/2" hole in the nose cone. This is not a permanent fix for flying, the light would need to be securely attached, perhaps inside the nose, in a way that would not let it fall out easily but would allow turning it on and off.

For more info on obtaining the Finger Lights, Google the keywords: L E D finger light. The black strap is a Velcro strap that allows strapping the light to a finger.

The most practical thing might be for someone to buy some on eBay like 12 to 20, at a good per-light price, and sell them to club members. Otherwise, the only times I've found these for sale in stores was either at the Wal-Mart (Homewood-Wildwood) 10 items or less (and cigarettes) Check-out line, and at a dime store type store last fall among their Halloween items. At a price of about $2.00 each.

You might also check stores like Dollar General.

Places to look for night flying supplies

After we started looking for items to illuminate our rockets we were surprised by how many different items there are and where you could find them. Glow sticks, earrings, finger lights, glow wire, bracelets, necklaces, etc. of various sizes and colors can be found at Walmart, Dollar General, Dollar Store, Auto Zone, Hobby Lobby, Michaels, etc. Be sure to look in the sporting goods department and automotive sections too. There are many places online that feature even more items.

While it might be possible to attach some type of illumination to the outside of an existing rocket, I generally don't recommend doing it, especially with the smaller rockets, but if you would like to try and modify an existing rocket, that will be ok, but make sure you do not adversely affect the cg /cp relationship of the rocket or add too much weight. weigh your rocket fully prepped and make sure the engine you will be using will provide enough power for a safe flight. In this case, larger is better.

If your modification is to simply tape a couple of glow sticks, l.e.d.'s, etc. to the main body tube of an existing rocket, also make sure to use clear packing tape. Packing tape has a lot more "stick" and a higher tensile strength than regular clear tapes like Scotch Magic tape.

Obviously purchasing a clear payload bay kit from Estes, Quest, etc. is one option but if you'd like to build one of your own designs from scratch or make a simple clear payload bay for one of your existing rockets you can pick up some clear tubing at Lowes or Home Depot. It is most commonly used as a protective sleeve around florescent light tubes. You'll find it in at least 2 diameters and 4'-8' lengths, so you could make quite a large bay or several.

The larger of the two sizes I have seen is a perfect fit for a bt 60. All that would be needed here for a retro fit of an existing rocket, would be to cut a piece of tubing long enough to carry your light source and attach between the upper end of the bt and the nose cone. If your new payload bay is too long you might need to replace the shock cord and make it a few inches longer.

I have attached a photo of 2 of our payloaders for new flyers, to give an idea of what can be done.

We've got the rocket design that we want... thanks to George Gassways photos from NARAM. Now all we need is to find the right type of lighting fixtures...

Well...

The first Night Time launch was a "BLAST"...

Even if my rocket couldn't hold its self together on it's first landing...LOL!!!

That's OK... we'll be back (next time I might let the glue dry first...!!!)

If you missed it... it was a treat... beautiful WX... in fact I think I'll lobby for ONLY night time launches...
Not really, but it was that nice...!!!

Without a doubt this was a special launch and night flying needs to be part of our schedule several times per year.
