For a variety of unfortunate reasons, I will be unable to go to BALLS as planned and although I plan on attending Oktoberfest and doing at least 1 LCO and 1 RSO stint, I may not fly anything at all......

If previous history is any indication, the launch trailer and equipment will show up by noon on Thursday and setup will be done that afternoon, weather permitting. I'm not personally towing the traile...

An RRC2X won't help you for airstarts as it is purely a deployment altimeter. It will fire a charge at apogee and then again at a programmable altitude lower than apogee. The outputs of an RRC2X will ...

From the boat building biz, the proper way to deal with the fabric weave is to do a process called "fairing". (As in to make something look "fair" or pretty). You use epoxy mixed with glass or silica ...

I would like first LCO shift on Saturday (8AM-10AM) and a Friday afternoon LCO shift. Warren

Just a reminder that there is a pre-Oktoberfest equipment cleaning and maintenance party at Dale and Patty Netherton's place in Windsor on Saturday September 16th from 10AM or so until we're done. NCR...

Tell me about the fins. Flutter is readily cured by building up the fins with different resonant frequencies and a taper from base of span to tip. My original SSS bird on an H180 sim'd to just Mach 2 ...

I personally don't pay much attention to NAR records as they're not even close to Tripoli records the last time I looked. Tripoli world records are available on the Tripoli website. Our records are lo...

I always place my bulkheads either midway in the piston or on the side AWAY from the charge. Warren

There is a major difference in fit between Hawk Mtn or GLR filament wound and their corresponding coupler material and the Performance Rocketry tubing and its corresponding couple material. The first ...

I got into PPG as a result of the local vendor... right out on Main St. in Longmont and the only one who would talk to me and educate me. Warren

Personally I'm a big fan of the PPG paints... of course, others will have different opinions... Warren

I've done it, can't comment though on durability. They didn't peel in flight at least. Then the bird cored and that fancy paint job was moot. Warren

For birds 4" dia and below, I use 2-56 nylon screws. I use 4-40 on some 4" birds and above. 2-56Clearance Hole = 3/32"Tap Hole = 5/64" 4-40Clearance Hole = 1/8"Tap Hole = 3/32" Warren

I've used pistons in 29mm through 54mm birds, but I've never used them in anything larger. At the last launch I flew at (June I think), my 4" project didn't properly deploy the main and suffered some ...
