And here's the follow up single, "The Bertha Butt Boogie"

Good to see Coke sponsoring a rocket contest somewhere. Wish they'd do it here!

Mr. Whipple is dead, and there is nary a man that can replace him. Squeeze away.

climbing trees/obstructions to retrieve rockets, and especially using implements to retrieve rockets from power lines. Such power line incidents have caused the ONLY rocketry related fatalities in...

you mean the bag deformed the tube?

Ok, so then you go to control panel, default programs. take the second link (should be "associate a file... with a program"), select ".rkt", see what it says under "current program" (should be Adobe...

Re-install or repair-install RockSim; that should fix the file association. At the very least it should register RockSim as something that knows about a .RKT file so that you can set the file...

The initial composite hobby motors, RDC and Centuri's Enerjets, did not produce smoke, and they didn't have much of a flame either (sometimes you couldn't see anything until the rocket got up high...

There's just gotta be someone who can come up with a convenient *mechanical* method for ejecting a parachute, at least for smaller ( 3" diameter or below) rockets.

1. All Estes motors come with igniters (except the Pro-Series II E-F-G motors)
2. Hobby channels (Hobbytown, Hobby Lobby, Fry's, your local hobby shop) sell wadding and igniters separately
3. ...

Super glue is good at lots of things but a shock cord mount is not one of them. Wood glue would have been fine; epoxy would work but would have been overkill.

Resist the temptation to deviate...

1971 -- Enerjet E24 in a wallpaper tube rocket with 3/8" thick balsa fins and a nose cone turned on a Mattel Power Shop.

Someone, maybe Steve Jurvetson? flew a first gen iPhone in a rocket running a special app that used the accelerometers to try to record flight events, but the accelerometers were overloaded during...

Yer wrong, pard'ner. Those are the "Intertubes".

I continue to be amazed at the reaction to Windows 8. I myself normally jump on the latest Windows in the alpha test, a year or so earlier than its "release" to the general public. But I didn't do...

I'd rather have a Zinger. Or a Koo-Koo (which they changed the Ding Dong to, fortunately).

Jolly Logic responded that they had nothing to do with the Estes product.

Registered! Gotta arrange the cat-sitter, and make sure my 10 year old Accord will make the trip, but it's time for a pilgrimage to Penrose.

Or, in the southeastern states (excepting Florida, apparently), there is the White Castle equivalent http://en.wikipedia.org/wiki/Krystal_(restaurant)

Saturn V is BT101, BT80, BT58.

Saturn IB is BT80 and BT58, with two other sizes for the aft skirt (about 2.7") and the fuel tanks (0.7") (which would be the same for the Redstone, because the...

The later B14 motors were actually semi-cored. I have a few late B14 motors that appear to be essentially the same as early B8 motors. The core is the same depth, and the nozzle is only slightly...

Mike, I will put this up on SoAR's Yahoo Group. There's a launch this weekend (if the rain stays away) in Lilly, GA. and I'm sure someone would be glad to take some of those off your hands.

The nose cone was slightly different. Without consulting the numbers that I have somewhere on this computer. One nose was a couple of inches longer than the other, and the ogive section was 10"...

Not sure what you mean by "more than our annual dues." I'm assuming you mean more than you collect from everyone per year?

The usual hosts (such as BlueHost.com, HostGator.com, ClickHost.com)...

Long pintles. Dave Bucher recently put up pictures of a number of F100 and E60 pintles, some still in good condition, from the FSI inventory he and his partners recently bought.

You are correct. That has been true since about 1999. Before that, Quest manufactured their own motors, or had Flight Systems Inc. make them. Flight Systems went down in 1994, and Quest briefly...

Not sure what you mean by "lower stuffer tube shroud." Do you mean the scalloped shroud that goes around the "fuel tank" tubes?

The pattern for that comes directly from the Estes pattern, which is...

If you've got the PSD, you may indeed have a way to separate the background from the foreground. In Photoshop, just turn the background layer and all other layers off, and then save the foreground...

Fishing leader line, I think (Edit: though I might stand corrected now from Matt). After I built my first NCR kit, I went to a deep sea fishing supply shop and got enough to last awhile. I got the...

They are a spin-off of HobbyLinc. Based in an eastern suburb of Atlanta. Uses Estes parts, or at least did at the beginning a few years ago. The only problem in their early kits was they often put...
