So if been reading here and there that you can use crepe paper as wadding. Is it true? If so can save some money

I agree but you end up buying more than you need but it won't go bad and you can share with your friends.I don't think you can beat dog barf for the cheapest per flight. You just have to buy a lifetime supply up front.
Why don't you use recovery wadding with a parachute isn't that what the instructions say to do.So if been reading here and there that you can use crepe paper as wadding. Is it true? If so can save some money

What is your soaking procedure? I have an old box of borax and many worn out pairs of, well, menās undergarments.Soak anything you want in Borax and go your hardest.
I've got a pair of undies as a drogue 'chute.
Proves the point of "hanging out the laundry"

I picked up some flat packs of flame resistant crepe paper at the local āparty cityā type of store. I cut it to the same size as Estes recovery wadding squares and it seems to work. It is a little thicker and a little stiffer than Estes recovery wadding. I just never know how much of the crepe paper stuff to use.I bought some crepe streamer at a Dollar store & tested its flammability. It charred but did not ignite. Two rolls for a buck. Each roll 1.75" wide by 70' long. Lots of wadding for $1.
On some of my more beloved rockets, where weight is not a critical issue, I have started using nomex blankets. Work well. A little expensive, yes, so I use them only on my favorite rockets I really would hate to lose. Never had a problem with parachutes being burned when using a nomex blanket. Got them from Uncle Mikeās Rocket Shack a few years back.So if been reading here and there that you can use crepe paper as wadding. Is it true? If so can save some money

@SkyFire pretty well nails it above with the video. Just using borax instead of bicarb.What is your soaking procedure? I have an old box of borax and many worn out pairs of, well, menās undergarments.
You'll get better flame retardancy if you use a combination of boric acid and sodium tetraborate (borax); they increase the solubility of one another and both are good retardants. Try 7 oz borax and 3 oz boric acid (termite killer; check label) in a quart of boiling water to give a saturated solution for dipping TP, paper, cloth.... The precise ratio isn't life-or-death; even a 50:50 mix by weight will work fine, and better than either chem alone.What is your soaking procedure?

What size and shape do you cut it to? Any rule of thumb for how much to use?I've been using crepe paper party streamers for years. Our family always decorates bedrooms, bathrooms, dining room, etc. for everyone's birthday. When the birthday's are over, I bag it up and throw it in a rocket box. I'll probably never run out.
What size and shape do you cut it to? Any rule of thumb for how much to use?
Great idea!FWIW... here's what I do..
On larger BT's I prefer however to tape a dime to one end of the party streamer, then roll the paper around the dime until the crepe paper is a slip fit into the body tube. It's an awesome visual, that long streamer slowly falling to earth. It also gives you a good visual as to the direction the rocket will be from the launch pad.
I just tear it so that it's a little wider that whatever diameter body tube I'm stuffing it in. Then, since that often leaves gaps that the short side of the streamer, I tear a second (and maybe a third) and place it on top but rotated 90 degrees. Then, I usually use a pencil to push it gently down the tube, then the parachute or streamer, or whatever goes in on top of that. Not very scientific, but it works well enough.What size and shape do you cut it to? Any rule of thumb for how much to use?
If rolled around a dime, how does it stop the ejection charge from reaching the laundry?FWIW... here's what I do..
On small diameter rockets, simply roll it until it's a slip fit into the body tube.

Slightly off topic, but I used to have a homemade streamer (fairly small) that had a penny taped to one end to weight it. The āpenny streamerā was placed in the model rocket tube, rocket got launched, and penny streamer got ejected. We then timed how long it took for the penny streamer to hit the ground. The speed at which it was falling times the amount of time to hit the ground = rough altitude at ejection. If time of ejection was close to time of apogee, then we could get a rough idea of how high the rocket went. I thought the only reason for the streamer was so you could see it and that the penny by itself would be a better object to use. That is not the case. The streamer slows down the penny enough that you can time its fall.If rolled around a dime, how does it stop the ejection charge from reaching the laundry?
