Hi, folks. At my latest launch of LPR rockets at a local park I noticed that that the Estes wadding did not come out of the body tubes on these two rockets:
Cosmic Cobra: BT-56 tube (about 1.3 in in diameter)
Scratch Built: 29mm tube
i used 5 1/2 squares of wadding in the 29 mm and about 5 squares in the Cosmic Cobra BT-56.
Both nose cones came off at ejection. Both parachutes came out.
But the wadding, scorched on one side, stayed in the tube.
Is it supposed to eject?
Is it ok if it doesn’t?
Is there a special way I should insert it? (I just shove it in.)
Should I try a different wadding? Dog barf? Squares of flame resistant crepe paper?
Is there a rule of thumb for how many squares of wadding to use? Am I using too much?
