For competition, it sounds like its ok to eject the engine, provided you provide a recovery device to return it to the ground safely, right?
That being the case, if you attached a streamer to a length of kevlar line, then attached the end of the line to the edge of the engine with a drop of superglue, would that be acceptable, or would that constitute an "engine modification"? The recovery device can easily be reused by simply scraping it back off with an razor knife to glue to the next engine.
