Same as the original Chimera with a shock cord retainer integrated. I also build an EBay for the center tube but I want to test the airframe before employing that. The middle tube can be screwed onto the top and bottom tubes and the Ebay is also retained with screws. I built a passage under the Ebay to allow ejection gasses to push the nose cone off without electronic deployment. This allows for the flexibility to use motor ejection or even dual deployment.
I launched this on an F67 at Hartsel, Colorado and it flew amazingly. There were no electronics on this one so I would estimate the altitude to be around 1,200 ft
