I received the new "Make: High Power Rockets book in the mail yesterday.  It is very well done.  It is not as thick as the first book but full of great information and advice.

Rocket Motor Tutorial Primer:

Mr. Gary A. Crowell Sr.  made a wonderful MS-DOS software presentation providing data on rocket motor basics, including not just a standard Estes motor, he also included composite motor data on how a single use composite motor and how reloadable motors work. The program can still be found on the web.  However, it will require windows 98 or Windows XP to function.  I will post the items presented by him here in pdf format.  It is a great learning tool for those who want to learn more about rocket motors:

Launch Pictures / Rocketober 2017 OROC Launch Report
« on: October 30, 2017, 11:13:15 AM »
The Oregon Rocket Club had an amazing three-day picture perfect weekend launch October 27th-29th.  I and Danel Peirce were able to make it to the Sunday launch day. I had taken my 3-inch diameter Fat Cat F-104 Star Fighter Rocket.  It went up on 29mm motors. Daniel took a nice collection of his rockets which consisted of the Launch Pad Nike Ajax, the 4-inch diameter Der Big Red Max, the 2.6-inch diameter fiberglass MadCow Honest John, and the 2.6-inch Mad Cow Bomarc.
The OROC club and one rocket that achieved 34,0000 feet over the weekend.
The event was postponed by one weekend. The weekend before which it was originally scheduled for had early morning snow.
My F-104 Star Fighter went up on a 29mm 3-grain CTI G-125 redline motor with a 7-second delay.  Since this was its first flight, it was launched on the away pad for extra safety precautions.  The rocket went perfectly straight up and looked as it was flying. The did three rotations during it straight up ascent. The delay was a tad long. The next time when it gets launched on the same motor the delay should be set for 5 seconds. The two parachutes deployed and the rocket landed in fine shape. the nose cone base section separated and the nose with its canopy landed in the sand without any damage.
Every rocket that Daniel Peirce launched (all four) was a picture-perfect flight.
A student from Clark College launched a rocket on an Aerotech 75mm L2200 green motor that was picture perfect as well. All of the electronics on the flight performed flawlessly.
General Rocketry Discussion / Latest Rocket Builds

I have been on a building rocket spree.  I built the classic Estes Maxi trio ( The V-2, Honest John, and Pershing 1A), then finished a classic LTV Scout utilizing 3D printed parts made by Boyce Aerospace, then finished a classic  FatCat rocket kit of the F-104 Starfighter that will go up on G or H motors.
Now to work in the 4-inch diameter Mercury Redstone using the Boyce Aerospace Redstone capsule.
General Rocketry Discussion / Tripoli archives in the works
« on: October 24, 2017, 01:33:22 PM »
The Tripoli rocketry members should have access to an archive similar to what fellow NAR members have through NARTS.

There is more than 33 years of articles and more than 168 issues.
Technically the interest began in 1964.

attached is an example of what work will be forthcoming to help save and provide an archive for Tripoli members. 

Goerge Gassaway has created a well-formatted forum to support those Interested in rocketry contests for NAR and FAI enthusiasts:

There are yahoo chat rooms discussing this topic, however, this forum may be more beneficial to the novice.
Launch Pictures / First FAA certified Launch
« on: October 16, 2017, 01:30:23 PM »
The GRC 790 had their first official FAA 3,500 AGL certified launch.  It went really well.  We did not push it too much with the site this day.  The process for calling Prescott Arizona 72 hours in advance was tricky.  The first person I talked to request the NOTAMS was an ass.  I waited about an hour later called back again and had someone else on the phone that was nice and easier to work with.  he provided me with a NOTAMS designator which I would provide to the Seattle Air Traffic Control center 24 hours ahead of the launch date.
The FAA web site had me on the blotter.
24 hours ahead of the launch day I called Seattle tower and the woman I talked with to request activation of the NOTAMs was very helpful and she made sure that the data on the NOTAMs was correct.
30 minutes prior to launching I had to call a different number to let them know we were about to go active and made sure that the phone numbers we had on site would work.
After the launch ended for the day, I called back 30 minutes after everything ended and closed out the NOTAMs.
It went well overall.

General Rocketry Discussion / FAA waiver approved:-)
« on: September 18, 2017, 03:00:21 PM »
I went on the NAR site and read the guidance instructions on how to submit for a FAA waiver.

I read it thoroughly and submitted one for our new club.  It was just for one day in October, November, and December and to see how our newly approved launch field will work out.  It is for 3,500 feet AGL.  So we can launch up to a low powered J.
I received the certificate today from the FAA office approving us to fly those days.  I am excited.
You have to call 72 hours ahead of time to one ATC site first to let them know, then 24 hours ahead of time to a different ATC site.  Thirty minutes before going active you have to call again and provide a good phone number with the tower in case something arises. Then the NOTAM will be active.

Gorge Rocket Club 790 Club Launch August 26th 2017
Our club had a nice launch this past weekend.  We did have one rocket motor failure that I hope Aerotech can help address.  Dan Peirce built a nice Pro Series Red Max with custom Vinyl letters from Sticker Shock.  It was going to be launched on an Aerotech 29mm G76-7 Mojave Green two grain reload. Dan is experienced with the Aerotech reloads and recently certified to level 1 with an H-128 out at Brothers in July.  It was a picture perfect flight. Why this motor failed is beyond me.

Bomarc Launch on an F24-4:

I submitted a motor failure report and contacted Aerotech.  This should NOT have happened.
