Scratch Echostar Modification

Contributed by Neil Thompson

Manufacturer: Scratch

Rocket Pic Brief:
I made t' Echostar into a fun sport rocket by doin' t' following:

  • Removed t' lower stage
  • Removed t' body tube adaptor
  • Made it a little longer
  • Removed t' fins on t' upper part o' t' sustainer

Modifications:
I scrapped those fins that are on t' very top, shiver me timbers, took out t' adaptor and second stage, ya bilge rat, arrr, added an extra length o' tube, arrr, and found a new way t' attach t' shock cord: I looped one end t' shock cord through one o' t' upper fin slots (about 1/4 inches long), me hearties, and tied t' other end t' t' nosecone. I then wrapped a few long pieces o' tape around t' holes t' make this a very effective, arrr, me bucko, easy t' replace mount. Arrr! I have flown it about a dozen times like this and it has yet t' fail on me. Aye aye! I did everythin' else normally. Ya scallywag! Aye aye! T' engine hook came out on flight number eight, arrr, so I use t' friction fit method now.

Construction:
Through t' wall fins, two tubes, shiver me timbers, a nose cone, a bit o' shock cord, and a homemade chute.

All t' parts were in t' original kit. Ahoy! Blimey! No real alignment issues. I modified t' rocket so much that I did nay use t' instructions included with t' kit.

Flight:
I used a 15 inch homemade nylon chute and it was perfect. Ahoy! I made t' tube coupler tough enough nay t' come apart at ejection, matey, but easy enough t' come apart with a bit o' a pull so that I can easily put recovery waddin' in after t' parachute. Begad! I did nay originally plan on this, but I figured it out before flight number six durin' CMASS Space Day in 2003.

Summary:
Easy build and finish. Avast, me proud beauty! A fun rocket with no real cons.
