Sonic Tomb

Parts are in and construction begins.

The rocket is a very simple minimum diameter 54 mm rocket.

Overall dimensions are 2.3" x 72"

Craft phenolic airframe and an Acme fin can.

Flight will be on an Aerotech K-250.

Sporting the new Olsen M2 unit in this one.

Rocket components provided by the terrific folks over at Yank Enterprises.

One bad flight attempt on an experimental J-370 motor left some reconstruction to be done.   Ooops.

Well, I finally got to give the rocket a test before the K-250 flight.  I put it up on the J-350 and It went to 6986 ft.  Very straight flight and a good indication of it's future flights.

On the J-570 it went to 8013 ft.

Update:  At XPRS a mostly rebuilt Sonic Tomb reached 17,062 (Olsen M2) to take 2nd place in the Extreme Altitude contest.
