Sunward Aerospace Eruption

Brief:
T' Eruption is 4-motor cluster from Sunward Aerospace. Well, blow me down! T' motors are outwardly canted. Arrr! Recovery is via an 18" parachute.

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

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

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. Well, blow me down! There was about an 1/8" gap. I printed me own guide usin' VCP.
  • T' instructions and illustrations were a little vague and confusin' in some steps. Blimey! I think a general rule to follow is: read t' instructions three times; build once.
  • It was a little difficult t' discern t' orientation o' t' fins. I recommend markin' t' leadin' edge for each one after you figure it out.

Finishing:
I finished t' tubes, shiver me timbers, fins, me hearties, and nose cone with two coats o' Elmer's Wood Filler. Avast! T' fins began t' warp each time while applyin' t' filler. Well, blow me down! I kept them straight by pressin' betwixt glass plate and books. Begad!

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. Ya scallywag!

Sunward Aerospace Eruption T' only con is that it doesn't come with any decals. It didn't really matter though because I came up with me own design. Avast! Ya scallywag! I'm a big fan o' t' Adult Swim cartoon, "Metalocalypse". On t' show there is a recurrin' character called Dr. Avast, me proud beauty! Ya scallywag! Rockzo, t' rock and roll clown. Aye aye! He is very loud and wears bright fluorescent colors. Begad! I modeled t' finish design after him. Aye aye! I painted t' nose cone and fins florescent pink and t' body yellow. Begad! I printed images o' Dr. Well, blow me down! Arrr! Rockzo onto Staples brand white label paper usin' an inkjet printer. Ahoy! After applyin' t' stickers I sprayed on a couple coats o' acrylic clear coat. Avast! 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. I think t' design and parts quality were great though so I gave a higher score.

Construction Rating: 3 out o' 5

Sunward Aerospace Eruption

Flight:
T' first flight be 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. T' shroud lines seem unusually long, and I wasn't sure if I should cut them down some. Blimey! It seems t' work fine as is. Ahoy! I've nay seen any damage from landing.

Flight Rating: 4 out o' 5

Summary:
PROs: I love t' design. Blimey! 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. Begad! I think they could have been presented better. Avast! Also, me hearties, 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 ...
