Need a plugged motor with no ejection charge but can't find one with the right impulse? We get that question all the time. It's very rare that you would ever fly a rocket that doesn't use an ejection charge, but there are some cases where a clustered rocket may require plugged motors on the outer motors where there is no place for the ejection charge to go. Important Note: Plugging a motor is not approved by Estes, NAR nor Tripoli. It is considered a motor modification, so they can't be flown at launches insured by the NAR, Tripoli, nor at AMA launches which follow NAR guidelines. As the video suggests, the best alternative is to vent the ejection charge to the atmosphere.
