I be goin' t' fly this on an E15 but for some reason I could nay get it into t' motor mount.  I know that thar be a section o' t' motor mount that was deformed slightly because I used too much glue when I assembled it, but I've never had a motor that wouldn't fit with a little bit o' effort.  Long story short, I loaded up a new E20 instead and let it rip.  Off t' rod like a shot, arrr, lost it against t' high clouds shortly after burnout.  Heard t' ejection pop but never caught sight o' it.  Put t' wind at me back and started walking.  Got lucky in that thar was a couple o' folks out on t' range recoverin' rockets and one o' them had seen it land.  Recovered on t' field with no damage.  I'm goin' t' have t' go with less motor or have better deadlights with this bird if I don't want t' lose it.
