Quick Question about wadding
Is there a good alternative to the wadding instead of purchasing it from a hobby store at a jacked up price? It looks like basic tissue paper. would this work the same? like the stuff for wrapping presents, white tissue paper. i just dont want to start my rocket on fire. Thanks in advance!

Tissue paper won't safely work as it burns (and will come down on fire and start other fires) !
What you want is commonly called "dog-barf" which is a funny name given to blown-cellulose insulation. You can get a huge bag at Home Depot/Lowes for very little $$, and it is treated with flame-retardant. (one would not want FLAMMABLE home insulation now would one?). You would use about a 2 1/2 body diameter high stack in the tube on top of the engine below the parachute/streamer. Wadding type items that are NO good (due to fire hazard) : Kleenex Toilet Paper Paper towel Tissue paper Newspaper Cotton Balls Wadding/Recovery type items that are acceptable : Dog Barf (Cellulose Insulation) Model Rocket Wadding Permanent Nomex/Kevlar Heat Shields tied to the Shock Cord Ejection Baffles Piston Ejection (Mid/High Power Rockets only)

One thing to add about this product -- at DIY centers, like Lowes or Home Depot, you can get a huge bundle of this stuff (like a 12" x 18" x 24" plastic-wrapped block, tightly-packed) for about 3X the price of just one package of regular wadding sheets, or roughly about $6-$7. It will take you several years to use up that much, even if you give some away to friends.

More wadding alternatives
Quote:
To these I will add: o Party paper - ie, streamer and crepe paper (Double check the labels, but most of these are treated to be flame retardant.) o Tissue paper used on parade floats (I understand that's what Quest wadding is.) Doug |

Wadding type items that are NO good (due to fire hazard) :
Kleenex - been there Toilet Paper - done that Paper towel - t-shirt has burn holes in it Tissue paper - yeah Newspaper - no Cotton Balls - yeah, but they look cool floating back to earth smoking You want proof? It's right here on the lower left. Guess I've been rehabilitated.

I tried virtually all of the items I listed as unacceptable....
For most of them, I found out the HARD (by setting grass/field fires in my younger and much less sensible days ) way that they are unacceptable !
