(Scratch) SkyScreamerBrief:
T' SkyScreamer is a scratchbuilt rocket made from an Estes Phoenix motor mount. T' name comes from an amusement ride that operated at Six Flags Astroworld in Houston, Texas. Avast, me proud beauty! T' rocket is basically a downscale Estes Der Red Max with full-sized Der Red Max fins.

Construction:
SkyScreamer actually started life as a motor mount for me Estes Phoenix. Aye aye! It is a combination o' scrap from me spare parts box. Aye aye! Well, blow me down! Blimey! T' parts are:

  • 1 Estes Phoenix engine tube (8" long BT-50)
  • 1 Estes Alpha nose cone
  • 1 launch lug
  • 1 Alpha motor mount
  • 1 sheet o' balsa wood for fins
  • 1 24" thin elastic shock cord
  • 1 12" parachute

Constructin' this mini-bird be very easy. First, I removed all o' t' old parts that made it a motor mount. Arrr! Blimey! Arrr! Blimey! T' slot for t' engine hook be filled in with Elmer's Fill n' Finish, ya bilge rat, t' remains o' t' centerin' rings were sanded down t' nothing, and t' engine block was pulled out. I ripped t' motor mount out o' an A.R.V. Condor that I had messed up on construction. Begad! Blimey! Next, me hearties, I cut out t' fins from a sheet o' model airplane quality balsa wood. Avast! Blimey! A considerable amount o' this rocket's inspiration came from t' Estes Der Red Max, so I gave it oversized Der Red Max-style fins. Lastly, shiver me timbers, t' shock cord was attached and t' streamer was attached. It was then ready t' finish.

Finishing:
T' finish on SkyScreamer is very different from other rockets I've built. Begad! T' black is nay paint, ya bilge rat, it is actually tape used for model airplanes. Arrr! Blimey! It went on very nicely and if applied without any air bubbles, it makes an excellent finish. Avast, me proud beauty! I only covered t' about 1/4" o' an inch from t' top o' t' fins. Begad! Blimey! Two o' t' fins were covered also. Begad! Blimey! T' rest that I did nay tape was painted Racin' Orange, which is a florescent color. Well, blow me down! Blimey! T' idea was t' be able t' spot it in t' air and on t' ground easily.

For t' decal, I found t' old logo t' t' SkyScreamer ride that was at Astroworld and printed it onto OfficeMax bumper sticker paper and carefully cut it out and stuck it on t' side. Avast! Aye aye! Blimey! T' finished rocket looks very impressive.

Flight:
SkyScreamer has flown only once. T' motor used was an A8-3. Aye aye! I used 5 sheets o' waddin' and loaded it like a typical rocket. Well, blow me down! Avast! T' rocket shot straight into t' air t' about 200 feet.

Recovery:
T' recovery system was a 50" streamer, arrr, which was a major mistake because it came in like a rock and popped a fin off. Aye aye! It can be easily repaired though. Arrr! I now use a 12" parachute with a spill hole.

Summary:
This was a simple rocket made from junk that can probably be used as a parachute duration rocket if modified slightly.
