  • ways to decrease the volum in the tube anybody know how with out causeing a fire? im launching a big kids crayon bank i made into a rocket ill be useing a size G Motor, the weight of this rocket is 24.52 oz or 695 grams its a 4 inch tube linght is 22 inches long, this is with out the nose cone on it,

  • @david1513 Are you talking about a stuffer tube? A tube inside a tube.

  • @jgraham1971 no i mean just a outer tube not a ejection tube in side a tube, ive heard of others says the volume of there tubes was so great that the chute wouldent deploy on ejection , to much mass in that area to eject the nose cone i should be ok others have made a crayon rocket thay had no problums with ejections of the nose cones,

  • @david1513 I myself would have a stuffer tube such as a Big Bertha has. That way it decreases the volume for the ejection charge and also keeps the recovery and center of gravity at the top.

  • Need to get to bed, talk to you soon. Happy building

  • no it was scratch built. and my friend Rob's Trident didn't work out. There was not enough pressure to even eject the cone. way too much tube volume.

  • I launched one of these babies on a vacant industrial lot along the Columbia River in Rainier, Oregon back in 1990. We lost sight of it after the second stage fired, and didn't see it land. An hour or so later we were driving across the Lewis and Clark Bridge, and I looked down into the review. Sure enough, a 3 1/2 foot long orange tube was floating right in the shipping channel. That was the first and last flight of my Comache 3. :)
