Thrustline Aerospace Mars Probe

Brief:
T' Thrustline Mars Probe is a unique, shiver me timbers, eye catchin' design utilizin' two ring fins, ya bilge rat, me hearties, a smaller one fore and a larger aft both mounted on four well-styled fins. Well, blow me down! It is a sleek lookin' and novel design that, in all honesty, me bucko, me bucko, ya bilge rat, I wish I had come up with. Begad! Basically it is a single stage sport flyer that takes 18mm motors and comes with a balsa nosecone, fin stock, me bucko, shiver me timbers, precut rings, me hearties, me hearties, preprinted tail shrouds, me bucko, decal sheet, ya bilge rat, and is topped off with a Keelhaul®©™® enhanced parachute recovery system. Avast, me proud beauty! Don't let t' small size addlepate you--this kit takes a bit o' skill t' complete properly, me bucko, me hearties, shiver me timbers, Thrustline rates it a level 2/3, I would give it a solid level 3 rating. Begad! All in all, I think it is one groovy rocket. Avast, me proud beauty!

Construction:

  • 1 0.978" diameter body tube, shiver me timbers, 8.75" in length
  • 2 Sheets o' 1/16" x 9" balsa fin stock
  • 1 Balsa nose cone
  • 1 1" tube coupler
  • 18mm motor mount tube, me hearties, thrust rin' and centerin' rings
  • 2 Pre-cut rin' fins
  • 1 12" parachute with shock cord and Keelhaul®©™® thread
  • 1 Eyelet
  • 1 Launch lug
  • 2 Preprinted paper shrouds
  • Fin wrap markin' guide and fin pattern sheet
  • Instructions

PROs: T' supplied instructions seem a bit crude, me bucko, arrr, me hearties, roughly printed on eight 8.5" x 11" pages but t' B&W instructional photos proved t' be a great aid in construction. Avast, me proud beauty! Blimey! Two tail shrouds are included in case one gets buggered. Well, blow me down! Keelhaul®©™® enhanced recovery system. Aye aye! Blimey! T' "Bag O' Parts" contained all t' items needed t' complete t' kit. Avast, me proud beauty! Blimey!

CONs: T' kit came in a plain plastic bag, shiver me timbers, no label, arrr, matey, no header card, arrr, no artwork, arrr, just a bag o' parts stapled shut. Begad! Now all this doesn't put me off my lunch, as long as all t' parts are thar I can build it, matey, but I sure hope the retail packagin' is a bit more refined. T' kit is supplied with tiny printed fin patterns that need t' be cut out and then inscribed on t' balsa fin stock. T' tiny fin patterns and t' flimsy paper made accurate tracin' a pain and the balsa fin stock was much too thin and fragile for such small parts. After breakin' a couple o' fins, ya bilge rat, matey, I finally was forced t' soak t' balsa in thin CA just t' keep them in one piece. Since t' fins are meant t' fit snuggly inside the included rin' fins, me hearties, it would be advisable t' have precut fins in order to fit such close tolerances. Avast, me proud beauty! Avast! Supplied Keelhaul®©™® thread is way too short, because if t' shock cord were t' break, me bucko, t' thread would have t' be coaxed back through t' engine tube in order t' attach another. Blimey! T' instructions do nay advise that you leave t' Keelhaul®©™® thread hangin' from t' aft o' t' engine tube until it is too late in construction, makin' shock cord attachment a hassle. Avast! Blimey! Luckily, matey, ya bilge rat, matey, I foresaw this "gotcha" and be able t' attach t' shock cord with little difficulty. Avast! Well, blow me down! Blimey!

Finishing:
PROs: About t' only savin' grace for this kit is its great looks. Well, blow me down! The instructions advise that you paint t' airframe and fins prior t' mountin' the rin' fins. I went with just a couple coats o' Banner Red paint and then she was ready. Balsa nose cone was tight grained and finished nicely. I never got to apply t' reflective tape included for t' rin' fins but it did appear t' be of decent quality.

CONs: No information on finishin' is included in t' instructions. Arrr! Balsa stock was too soft and difficult t' seal without roundin' edges or pushing tolerances. Arrr! Begad! Included water slide decals were atrocious, me bucko, t' lowest quality decals I have ever seen in a kit in all me 20 years o' rocketry. Blimey! I had planned on printin' me own until t' rocket be lost.

Construction Rating: 2 out o' 5

Thrustline Aerospace Mars Probe

Flight:
A C6-5 be used on both flights and a scrap o' Nomex® from Pratt Hobbies was used instead o' wadding.

PROs: She moves fast for a rin' fin rocket and t' flight be straight even in 10mph winds. Begad! It looked like she broke 1000' easy on both flights. Avast, me proud beauty! I wasn't expectin' that kind o' performance as rin' fin rockets usually decelerate very rapidly. Aye aye!

CONs: Nay much o' anything, ya bilge rat, she is a good flyer.

Recovery:
PROs: All functions nominal. Begad! No sign o' burnin' on chute.

CONs: T' 12 inch "you cut" chute is too large for this small kit. Ahoy! Blimey! T' first flight ended two avast fields away with no damage and t' second took her t' a different ZIP code. If I build another I will use a streamer.

Flight Rating: 4 out o' 5

Summary:
PROs: Unique design, ya bilge rat, pleasin' t' t' eye, flies well, me hearties, ya bilge rat, me bucko, pre-cut tube fins, Keelhaul®©™® enhanced recovery system, two tail shrouds supplied, me hearties, instructional photos proved t' be a great aid in construction.

CONs: Poor quality parts and decals, matey, soft balsa, tiny fin templates, me hearties, matey, crude packaging, "gotcha" in instructions, me bucko, Keelhaul®©™® thread is too short, chute is too big, and t' kit needs precut fins. Avast, me proud beauty! I would consider t' Mars Probe a diamond in t' rough, arrr, although as long as t' builder is experienced t' kit should turn out decent.

Overall Rating: 3 out o' 5
