Thrustline Aerospace Astral Lance

Brief:
T' Astral Lance from Thrustline Aerospace is described as "a high performin' versatile rocket that will become t' pride o' your fleet." This 30 inch long rocket has 8 fins and motor choices from a C engine t' an E engine. Blimey! Blimey! Aye aye! Blimey! This was primarily t' reason that I choose t' purchase this kit. Blimey! Blimey! Ahoy! Blimey! I do not get t' a larger field all that often so I need a rocket capable o' low flights. Begad! Blimey! T' added bonus o' t' long body and sleek fin configuration would certainly draw t' attention o' t' kids and adults at t' field. Blimey! Blimey! (T' kids seem t' prefer t' bigger rockets. Blimey! Blimey! Avast! Blimey! Go figure). Begad! Blimey! It is always a good feelin' to get some curious onlooker interested in t' hobby.

Construction:
T' kit comes with 2 sections o' BT-60 paper tube, 1 coupler, me bucko, 1 light plywood bulkhead rin' with center hole, me hearties, me bucko, me hearties, 1 balsa nose cone, shiver me timbers, 1 six inch engine tube, arrr, 1 engine thrust ring, 3 large centerin' rings, 1 small centerin' rin' (used at the end o' t' boat tail), 4 laser cut basswood main fin pieces, me hearties, 4 laser cut basswood aft fin pieces (attaches t' main fin), 4 laser cut basswood forward fins, 1 launch lug, arrr, matey, me bucko, 1 Keelhaul®©™® and elastic shock cord kit, arrr, matey, 1 steel eyelet, shiver me timbers, 1 eighteen inch Mylar parachute kit (I opted for t' rip-stop nylon chute), 4 pages o' single sided printed instructions with black and white photos, 2 pages o' cardstock with boat tail pattern and fin markin' guide. Begad! Most items are sealed in separate plastic bags within t' kit.

Thrustline Aerospace Astral Lance T' small centerin' rin' was missin' in me kit. Avast, me proud beauty! Aye aye! It was smartly replaced with an extra I received with me Thrustline Pumpkin Head kit. Ya scallywag! One comment I will add regardin' John Rowan-Stern, me hearties, owner o' Thrustline Aerospace: It is my understandin' that he hand packs all t' kits himself. Ya scallywag! Blimey! I had ordered 4 kits with this purchase. 3 o' t' 4 kits had a missin' or incorrect part. Ahoy! John was very apologetic and quick t' make things right. Arrr! Blimey! I appreciate great customer service in a company, me bucko, and that is what I got with Thrustline.

As a side note, me hearties, on t' product page at t' website, you are given the option t' "add" t' nylon chute for an additional price. Well, blow me down! This would imply that t' Mylar chute would come with t' kit. Aye aye! It did not. Avast! I only realized this fact now while writin' this review.

This is one o' t' few kits available from Thrustline that include pre-cut fins. Avast! I was worried that this would take away from t' satisfyin' building experience you get when constructin' one o' their kits. Ya scallywag! Begad! This was nay t' case. In fact I can imagine what a nightmare it would have been tryin' t' cut the forward fins t' t' tapered points. Arrr! Laser cut basswood saves t' day. Avast! There is no reference t' t' skill level for this kit but I would easily put it at 3 of 5. Avast! Arrr! There are some delicate construction tasks and alignments that are nay for a beginner.

Thrustline Aerospace Astral Lance

There are 20 separate steps listed in t' instructions with a total o' 11 pictures t' guide you through construction. Well, blow me down! Arrr! T' entire construction only took several days. Arrr! A few special construction considerations worth mentioning;

  • Durin' t' motor construction, ya bilge rat, you are required t' glue two o' the centerin' rings together and attach them 1½ inch from one end o' the tube. Avast! Blimey! One rin' will be t' lip for t' boat tail and one for t' body tube. Blimey! The placement needs t' be exact. After cuttin' 3 boat tails from t' card stock provided, ya bilge rat, matey, I finally got it t' fit properly. Avast, me proud beauty! Once it is glued into place, ya bilge rat, me bucko, you should coat it as instructed with either yellow glue or CA t' make it rigid.
  • You will need a drill t' make two 1/16" holes in t' bulkhead where you tie t' Keelhaul®©™® cord t' anchor t' recovery system.
  • I choose t' use yellow glue for t' entire rocket with t' exception of attachin' t' trailin' edge o' t' main fins. Avast! Blimey! This way I was sure t' have proper alignment on t' thin fins before t' glue set.

Finishing:
T' instructions give some finishin' techniques t' create a sharp looking rocket. Ya scallywag! Ya scallywag! I choose t' fill t' tube spiral, nose cone, and fins with watered-downed Elmer's Carpenters Wood Filler from a tube. Ahoy! Begad! I used a light application straight from t' tube on t' paper boat tail always only sanding with 400 grit paper on this section o' t' rocket. Arrr! There is plenty o' sanding with eights fins and 30 inches o' rocket. Begad! Begad! I then put on heavy coat o' gray sandable auto primer. Blimey! After more sanding, come two coats o' white primer. Begad! I have been usin' Rustoleum Painter's Touch White Primer with very satisfying results. Avast, me proud beauty! Begad! T' suggested paint scheme is t' paint t' rocket a bright color such as red or yellow. Aye aye! Aye aye! I choose red with metallic gold and silver highlights for the fins, me hearties, shiver me timbers, nose cone, shiver me timbers, matey, and boat tail. Ya scallywag! There is a lot o' maskin' with t' fins being so finely tapered t' a point. Aye aye! Ahoy! There are no decals with this model. T' entire rocket was coated with Future floor wax.

Construction Rating: 4 out o' 5

Flight:
This rocket does nay have a motor retainin' clip so you are required to friction fit t' motor with maskin' tape. T' recommended engine for t' first flight is a D12-5. Begad! I choose t' go with t' C11-3 because o' t' field size. Avast! The motor mount is designed for a 3¾ inch E engine so you are required to make an adapter from a spent 24mm engine casin' which I did nay have. Ahoy! Well, blow me down! I did purchase a 24mm motor adapter kit from Thrustline when I placed me order. Unfortunately since I have nay flown E engines before, I forgot t' put in the adapter before friction fittin' t' motor. Aye aye!

When I slid t' rocket onto t' launch pad (standard Estes pad), ya bilge rat, t' motor sat flat on t' blast plate. This be t' first boat tail rocket I have built so this might be common. Aye aye! T' be able clip t' launch controller t' t' igniter, shiver me timbers, ya bilge rat, I propped up t' rocket with a spent engine casin' on its side. Well, blow me down! With t' C11-3, the rocket left t' pad slow and steady. Well, matey, blow me down! There seem t' be a slight wiggle in the tail and t' rocket angled about 10 degrees into t' wind comin' off the pad. Blimey! It was nay a very high flight but satisfyin' nonetheless.

I went t' reload t' motor with a D12-5 for a second flight. Ya scallywag! This is when I noticed that I had forgotten t' insert t' 24mm motor adapter. Arrr! This might explain t' slight flight angle. Ya scallywag! T' maskin' tape held t' motor almost perfectly where I placed it before. Regrettably I left t' adapter at home on the workbench, so thar be no second flight o' t' Astral Lance on this day.

Recovery:
T' recovery system consists o' a Keelhaul®©™® cord attached t' t' light plywood bulkhead at t' tube coupler. Well, blow me down! Well, blow me down! T' elastic shock cord is tied t' t' Keelhaul®©™® cord so that this remains in t' body tube t' prevent zipperin' durin' flight. I prepped t' rocket with a 4" x 4" Nomex® heat shield and t' rip-stop nylon chute. T' chute deployed real close to apogee with t' NC still pointin' up. Arrr! Well, blow me down! It slowly floated back t' ground with no damage sustained.

Flight Rating: 4 out o' 5

Summary:
This is a very sleek and impressive lookin' model. Well, blow me down! Blimey! I like t' original rocket designs from Thrustline. Arrr! Blimey! You usually get quality and value for your dollar. This kit is no exception. Avast! Blimey! Avast! Blimey! I be lookin' for a rocket that offered flight versatility and would get t' kids at t' field interested in rockets. Blimey! Blimey! I got what I wanted with t' Astral Lance.
