Estes oilet paper recovery wadding strikes me as a bit wrong for HPR rockets. What are some alternatives?
From: jack@rml.com (Jack Hagerty) Just go down to your local building supply store and get a bale of cellulose wall insulation. This is just shredded newspaper treated in the same fire supressant [as Estes recovery wadding]. A $5 bag will give you enough wadding to last years! From: jsvrc@rc.rit.edu (J A Stephen Viggiano) In order to avoid fallout, you might want to put the engine in *before* the [cellulose] wadding, or, for smaller rockets, a sheet or two of regular wadding underneath the fluffy stuff. Wayne Anthony uses cabbage leaves (you get more leaves per head [than lettuce], and they seem to be a little tougher than lettuce), and I’ve heard of people using grass. From: bmcdermo@ix.netcom.com (Buzz McDermott) I use acoustic speaker insulation. I costs #3 – $5 per bag at Radio Shack. It’s reusable, and one bag generally lasts me for dozens of flights.
