Oops... you just committed the cardinal sin... suggesting someone do a search... the vultures will now descend on you and burn you to a crisp with their flames until you are well done... LOL
Yeah, I could have posted some links, but you know the old saying, "give a man a link, he reads for a day, teach a man to use search, he has links for a lifetime..."
That didn 't make sense, did it...
Yeah, I should have posted some links...
Anyone ever DIYed versions of these and used them? I suspect the larger diameter body tubes would require multiple foam board thicknesses to prevent yaw in the tube.

Plugs – the is the most common wadding replacement in FAI competition style rockets. Foam plugs are made from the pink/blue closed cell construction foam. This can be done by making a cutter from a piece of body tube of the size plug you need. Take the tube piece and CA around the circumference of one end. This will be the cutting side. Take the tube and put it on top of the foam and slowly spin the tube while applying pressure. This will cut the plug from the foam. Plugs act like many piston and effectively help “push” out the chute in competition models.
Since I have Estes model rockets, I use Estes Recovery Wadding. What kind of rockets do you have? My advice is to use their particular brand of recovery wadding.
