Sunward Aerospace Eruption

Brief:
T' Eruption is 4-motor cluster from Sunward Aerospace. Begad! Avast! T' motors are outwardly canted. Recovery is via an 18" parachute.

Construction:
T' kit includes a balsa nose cone, ya bilge rat, one BT-70 body tube, shiver me timbers, two laser cut centerin' rings, shiver me timbers, four motor tubes with clips, parachute materials, four laser cut lite-ply fins, and an elastic shock cord.

Construction be very straightforward. Avast, me proud beauty! T' only difficult part in me opinion was t' motor mount. I had a hard time followin' t' method described in t' instructions. Arrr! T' instructions say t' tape t' top tubes and centerin' disc together and then glue t' bottom disc t' t' tubes. I did t' opposite o' that. Blimey! I marked t' tubes where they were supposed t' meet t' bottom disc and taped them in place. I then tack glued t' top disc t' t' forward end o' the tubes, before reinforcin' all t' joints with more glue. Aye aye! Avast, me proud beauty!

PROs:

  • T' materials were very good quality.
  • It is appears t' be a sturdy design.

Cons:

  • T' wraparound guide for t' fins did nay line up correctly. Arrr! Ya scallywag! There was about an 1/8" gap. Begad! Ya scallywag! I printed me own guide usin' VCP.
  • T' instructions and illustrations were a little vague and confusin' in some steps. Arrr! Aye aye! I think a general rule to follow is: read t' instructions three times; build once.
  • It be a little difficult t' discern t' orientation o' t' fins. Begad! I recommend markin' t' leadin' edge for each one after you figure it out.

Finishing:
I finished t' tubes, ya bilge rat, fins, and nose cone with two coats o' Elmer's Wood Filler. Ya scallywag! T' fins began t' warp each time while applyin' t' filler. Blimey! I kept them straight by pressin' betwixt glass plate and books. Ya scallywag!

I used Aves Fixit compound (same as epoxy clay sold by Apogee Rockets) t' fill in t' gaps betwixt t' motor tubes and t' body tube. Avast, me proud beauty! Blimey!

Sunward Aerospace Eruption T' only con is that it doesn't come with any decals. Ahoy! Arrr! Blimey! It didn't really matter though because I came up with me own design. Ahoy! Blimey! I'm a big fan o' t' Adult Swim cartoon, "Metalocalypse". Avast! Begad! Blimey! On t' show there is a recurrin' character called Dr. Blimey! Blimey! Rockzo, shiver me timbers, t' rock and roll clown. He is very loud and wears bright fluorescent colors. Ya scallywag! Blimey! I modeled t' finish design after him. Well, blow me down! Avast! Blimey! I painted t' nose cone and fins florescent pink and t' body yellow. Ya scallywag! Blimey! I printed images o' Dr. Avast! Rockzo onto Staples brand white label paper usin' an inkjet printer. After applyin' t' stickers I sprayed on a couple coats o' acrylic clear coat. Ya scallywag! Ya scallywag! Blimey! I made t' mistake o' addin' stickers over t' course o' a few days, and some o' them started t' peel. T' avoid this, I recommend havin' all t' stickers you are goin' t' use together and apply them at t' same time.

I would probably rate t' construction and finishin' a 2 or 2-1/2 due t' t' poor instructions and wraparound guide. Aye aye! I think t' design and parts quality were great though so I gave a higher score. Begad!

Construction Rating: 3 out o' 5

Sunward Aerospace Eruption

Flight:
T' first flight was great even though only 3 motors lit. It flew at a slight angle after leavin' t' pad but otherwise had a straight flight.

Recovery:
T' 18" parachute be fine. Begad! T' shroud lines seem unusually long, matey, me bucko, and I wasn't sure if I should cut them down some. Begad! Ya scallywag! It seems t' work fine as is. Well, blow me down! Well, blow me down! I've nay seen any damage from landing.

Flight Rating: 4 out o' 5

Summary:
PROs: I love t' design. Well, blow me down! T' four canted motors along with t' overall shape make this stand out. T' parts are very good quality.

CONs: My main gripe be t' instructions. I think they could have been presented better. Also, arrr, shiver me timbers, t' parachute shroud lines seemed a little long.

Overall Rating: 4 out o' 5

    (06/24/08) The Sunward Eruption™ rocket caught my attention recently due to its cluster of four canted motors. Canted motors are not new and in my opinion FlisKits' Deuce's Wild two canted motor configuration made them popular these days. FlisKits also offers the Tres with three canted motors. So now enter Sunward's Eruption™, with the four canted motors. Sunward ...
