    Stickershock23 CLOSING for a while

    Mark, Our thoughts and prayers are with you and Marian. Cancer sucks, but the silver lining is that it helps you to know what is important and it brings you closer to your family, friends and community. Business can wait. Supporting Marian cannot. You’re doing the right thing. Stay strong...

    Wildman Black Saturday 2013

    Hey Tim, This is going a very special sale. Chanukah starts on Thanksgiving this year!!!! I’ll be needing my stuff really early – that is, as soon as the order is placed. If anyone else is wanting priority delivery, I can find you a Rabbi for a quickie conversion. I’m not the poet...

    Pressure relief holes in the airframe in the area of the motor tube?

    Last year, Jackson put together a vent hole calculator to insure he was properly venting his N5800 rocket. You use it by inputting pressure data from rocksim and data for volume calculation. The worksheet will give an estimate of the maximum force generated within the space from the change...

    Balls 22 Projects

    Eric, Very cool projects. I look forward to seeing photo/video results. I wanted to pass on some tracking info that I learned from the fine folks at Aeropac the first time we went out to the Black Rock. The playa sand has something in it that messes with radio transmission. You want to...

    Carolina Rocket Mafia

    Great idea, Jim. Do you know how you could make this really, really different from the Chicago Rocket Mafia? If everyone in the Carolina Rocket Mafia actually lived in Carolina! Or, if ANYONE in the Carolina Rocket Mafia actually lived in Carolina!

    Midwest Power 11 Chicago Rocket Mafia T-Shirts.......

    I forgot that Sather is a poet, and a good one at that. Sather, when you get a chance, post some of your poetry. Do your "19 laws of rocketry" count as poetry? That's one of my favorites. If you look closely, you can see that it was taped to our wall in some of the shots of us on the Science...

    Rocketry Vendors in Chicago

    I live in the Chicago area and make all of my high power kit or building supply purchaches either through Wildman or on-line. There really aren't any stores in the area that you can walk into, unless you count Wildman's trailer at a launch. Good news is that delivery into the urban areas of...

    Aggressive Opposition: 98mm Minimum Diameter

    I told Manny in the Black Rock that I would show him the table I put together to analyze my rocket’s dynamic stability. Might as well post it here, since it’s come up. CCotner is right – not all rockets are Mongoose 98’s. One of the things that most of the scratch built minimum diameter...

    LDRS 33. 2014??

    Flying at Bong is a great adventure. All the same, I’ll put a few more details on Preston’s smart advice to fly smart at Bong, not just for Mark, but for all of the flyers new to Bong. 1) Dual deploy. The area right around the launch pad provides some very nice landing space. But, the...

    Black Rock Road Trip

    Alright Manny, I’ve read the other posts, and that suggestion to have a 2 meter mobile rig is a good one. Unfortunately, I don’t have a 2 meter mobile rig. I have one of those wimpy hand helds, but a very good antennae for hearing directional beacons in the 70cm range. I’ll see what I can do...
