Was at Hobby Lobby today and they had a pack of 2 E16-8 clearance priced at $8.99. Date code A-07-28-13. Haven't looked yet to see if these are know for quick disassembly. A quick run in OR shows the Estes Viking upscaled to BT60 would eject about a second late. Ought to be inexpensive to build, so if she blows it is no big loss. Down side is it goes to 1500ft. Too heavy for a streamer, and I have no intention of loading my JLCR in it. (unless I can verify that these are not on the BOOM list..)
