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……   Read more»

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 trailer so I can’t guarantee this and with myself…   Read more»

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 fire e-matches, but…   Read more»

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 and…   Read more»

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 located under the Contests link on…   Read more»

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 microballoons and…   Read more»

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

Bruce…We’re going to have to talk about you and your Nutsert tool crossing paths with me and my retainer and rings… perhaps even my airframe and av-bay…Warren

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 fits pretty sloppy and slides easily through the airframe….   Read more»

Conway, I’ll be happy to drive up to make the pickup and shoot the shit some time if you give me directions and a time to visit. I’d like to pick your brain anyway. I’m on sabbatical still and my…   Read more»

I’ll take both.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

Great pics Bruce…!Warren

I surely hope you’re flying while I’m LCO (Friday AM 8 to noon and Saturday AM 8 to noon). I’ll give good color commentary… LOL Warren

Unless you’ve gotten consistent separation with that amount of BP at least 3 times, I’d beef it up a hair. I’ve found that you want to use the lowest amount that gives consistent separation plus a bit more. Add a…   Read more»

Looks pretty damn good Bruce. Can’t wait to see it fly. I think mine will end up shorter, but I’m extending the booster to handle the longest 98mm motor casings commercially available as well as the Hypertek 98mm hybrids. Rear…   Read more»

I’ll bring some professionally sewn and certified climbing webbing as well as some of what my wife sews for me for rocketry to the next launch.Warren
