Rocketeer's Corner: July 2015
http://billsrockets.blogspot.com/2015_07_01_archive.html
Friday, July 31, 2015. A drag of a topic. As I mentioned in previous posts, this year's TARC competition will probably see many teams struggling to loft their two eggs to altitude without busting the weight limit on the rocket. Most teams use the Tim Allen philosophy when it comes to increasing altitude - use a bigger motor (more power! Rocksim screen capture showing Cd override panel (Click to enlarge). Effect of varying the Cd. Rule 1: USE GOOD WORKMANSHIP. Rule 2: ALIGN FINS AND LAUNCH LUGS PROPERLY.

Rocketeer's Corner: May 2015
http://billsrockets.blogspot.com/2015_05_01_archive.html
Sunday, May 31, 2015. As I begin construction of my first Geezer TARC rocket, I find myself confronted by a sobering aspect of this year's competition. Weight. As I ponder egg protection, I have made good progress on my first entry - a 4 engine cluster I call "Nemesis", after the Greek goddess of revenge. Hopefully, she will not end up too fat to fly. Open Rocket simulation of Nemesis under power. Monday, May 18, 2015. A Geezer's thoughts on the 2016 TARC challenge. Have fun in Paris! Altitude goal for q...

Rocketeer's Corner: November 2014
http://billsrockets.blogspot.com/2014_11_01_archive.html
Sunday, November 30, 2014. The progress in modern electronics never ceases to amaze me - I always thought that the Perfectflite PNUT - a scant 0.7 x 3" in dimensions - was small, especially given the wealth of data it provides. However, there are some very nice small altimeters that don't connect to a computer's USB port. Perhaps the most famous of these is the Jolly Logic Altimeter 2. My latest acquisition is Perfectflite's latest product - the Firefly. Subscribe to: Posts (Atom). Bring out yer dead!

Rocketeer's Corner: February 2015
http://billsrockets.blogspot.com/2015_02_01_archive.html
Saturday, February 28, 2015. Weather this month has positively sucked - bitterly cold and marked by freezing precipitation. This past week saw a major snow event; Huntsville received 8 inches of snow in a single day! From left: Beulah, Big Bertha, and a clone of the Canaroc Green Hornet,. Seriously in need of sanding and a second primer coat. In front of the. Rockets are some of the parts to a Centuri Micro-Probe clone. Should be appropriate for the rocket's name - what would a Beulah look like? Being a ...

Not Exactly Rocket Science: May 2015
http://wallyum.blogspot.com/2015_05_01_archive.html
Not Exactly Rocket Science. Sunday, May 3, 2015. And what do I know about this? Not much other than if I'm going to do it, it's going to be with something that no one else will do it with. Yep, an Estes Rascal on an A8-3. Nope, I didn't come anywhere close to the spot. I know what you're thinking. "What's with the crappy pic, Bill? Did you bring the wrong camera again? I distinctly remember plugging the card in the other day and thinking "Don't forget this on Saturday." Heavy, HEAVY sigh. The E9 had deto...

Not Exactly Rocket Science: August 2015
http://wallyum.blogspot.com/2015_08_01_archive.html
Not Exactly Rocket Science. Monday, August 24, 2015. B6-4 Field: Back in action. Flight #1 of 14 on the day would be the Estes Battle Damage X-Wing that I attempted to fly here the last time the field surfaced. This time I wasn't as lucky with the clarity, but I still got the picture that pretty much tells the story of the flight. Got more altitude this time. Won't be a next time. I didn't get the satisfaction of seeing it nose into the hard packed infield as the whole flight took place over the ...The A...

Not Exactly Rocket Science: April 2015
http://wallyum.blogspot.com/2015_04_01_archive.html
Not Exactly Rocket Science. Saturday, April 25, 2015. An hour to kill. Yeah, that's just sad. Ten years off meant nothing to this bird. The A8-3 flight topped was dead straight in the light breeze, topping out around the 200' mark. Recovery, however, still needs to be worked on. The shock cord tangled on the fins, but the chute brought the whole assembly down safely. It just wasn't pretty. I flew the Quest Apollo the last time I was out, but made the mistake of flying it on an A8-3 for a woefully underpo...
