The two 12" parachutes have been assembled and have snap swivels added.
One parachute was tied to the shock cord on the lower half.
The other joined to the screw eye on the nose block.
Remember:
With the single plate baffle, you will need flameproof wadding to protect the parachutes.
The nose cone might need screws or a wrap of tape (on the outside) to keep it together at ejection.
Fantastic, great build. Is the Ranger the same size as the Big Bertha? I know their are fin adjustments, just wondering what needs to be changed if doing this in a BT80 size.
ReplyDeleteHi Scott,
DeleteThe Ranger and Big Bertha were both BT-60 diameter models, both 24" tall. You can check the specs here in the 1971 catalog: http://www.ninfinger.org/rockets/catalogs/estes711/711estcat.html
