I have a rocket that I'm upscaling, and the motor mount is for a 24mm E size, but I only ever plan on flying it with a D so I'll always use the orange spacer for D engines.
However, for my first flight I'm seriously considering letting it go with only a C engine to test how well it flies. But... the 18mm C engine won't fit well into the 24mm mount.
When painting the rocket I've used a dowel that has a spent 18mm engine on the end, and then a spent 24mm engine over that, which holds the rocket really well. It occurred to me that maybe I could use a spent E engine, nozzle end up, as an adapter to fly on a C engine. Maybe I'd have to drill out the nozzle to open it up enough to allow the ejection charge to blow into the body correctly.
Has anyone ever done this, and does it work well? Or is there a better adapter to use in this situation?
