I am really confused how this happened in the first place. F40-10T and it still zippered 2". This is my first rocket. How do I fix? I am also making an AT Mustang. Can I do something to prevent this (Besides getting the motor right every time)?
Never used a piston but I'd like to try it. So is this design close to a piston? Wouldn't you just convert the coupler to a piston and anchor it to the motor mount? And of course keep the body tube the same length.coupler is on the bottom half of the rocket, so if anything zips, its a coupler not a BT.
i like pistons, so not a fix for me.
