Iris Payload on Black Diamond

This Iris payload section adds 4.7 inches to the rocket and 5.4 grams of mass, not very significant even to this light, minimum-diameter model. A C-power motor can still take this well out of sight. However the tiny streamer is not adequate for the payload and nose weight, it now sports a 4-foot by 2-inch mylar streamer, with much better visibility.
