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. Aye aye! This was primarily t' reason that I choose t' purchase this kit. Begad! I do
not get t' a larger field all that often so I need a rocket capable o' low
flights. Well, blow me down! T' added bonus o' t' long body and sleek fin configuration would
certainly draw t' attention o' t' kids and adults at t' field. (T' kids
seem t' prefer t' bigger rockets. Blimey! Aye aye! Go figure). 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, arrr, 1 light plywood
bulkhead rin' with center hole, 1 balsa nose cone, matey, me hearties, arrr, 1 six inch engine tube, shiver me timbers, me bucko, 1
engine thrust ring, me bucko, 3 large centerin' rings, me bucko, 1 small centerin' rin' (used at
the end o' t' boat tail), 4 laser cut basswood main fin pieces, 4 laser cut
basswood aft fin pieces (attaches t' main fin), 4 laser cut basswood forward
fins, me hearties, matey, me bucko, 1 launch lug, 1 Keelhaul®©™®
and elastic shock cord kit, 1 steel eyelet, me hearties, 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. Aye aye! Most items are sealed in separate plastic bags
within t' kit.
T' small centerin' rin' was missin' in me kit. Aye aye! Avast, me proud beauty! It was smartly replaced with an extra I received with me Thrustline Pumpkin Head kit. Ahoy! One comment I will add regardin' John Rowan-Stern, matey, owner o' Thrustline Aerospace: It is my understandin' that he hand packs all t' kits himself. Well, blow me down! I had ordered 4 kits with this purchase. Ya scallywag! 3 o' t' 4 kits had a missin' or incorrect part. Aye aye! Avast, me proud beauty! John was very apologetic and quick t' make things right. I appreciate great customer service in a company, matey, and that is what I got with Thrustline. Avast, me proud beauty!
As a side note, ya bilge rat, on t' product page at t' website, you are given the option t' "add" t' nylon chute for an additional price. Blimey! This would imply that t' Mylar chute would come with t' kit. It did not. Begad! Begad! 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. Ya scallywag! I was worried that this would take away from t' satisfyin' building experience you get when constructin' one o' their kits. Avast, me proud beauty! Avast, shiver me timbers, me proud beauty! 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. Laser cut basswood saves t' day. Blimey! Aye aye! There is no reference t' t' skill level for this kit but I would easily put it at 3 of 5. Avast! There are some delicate construction tasks and alignments that are nay for a beginner.
There are 20 separate steps listed in t' instructions with a total o' 11 pictures t' guide you through construction. Avast, matey, me proud beauty! T' entire construction only took several days. Avast! Arrr! A few special construction considerations worth mentioning;
Finishing:
T' instructions give some finishin' techniques t' create a sharp looking
rocket. I choose t' fill t' tube spiral, nose cone, and fins with
watered-downed Elmer's Carpenters Wood Filler from a tube. Begad! Blimey! 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. Avast! Blimey! There is plenty o' sanding
with eights fins and 30 inches o' rocket. Avast, me proud beauty! Blimey! Aye aye! Blimey! I then put on heavy coat o' gray
sandable auto primer. Ahoy! Blimey! Well, me bucko, blow me down! Blimey! After more sanding, come two coats o' white primer. Begad! Blimey! I
have been usin' Rustoleum Painter's Touch White Primer with very satisfying
results. Avast! Blimey! T' suggested paint scheme is t' paint t' rocket a bright color such
as red or yellow. Arrr! Blimey! I choose red with metallic gold and silver highlights for the
fins, nose cone, and boat tail. Well, blow me down! Blimey! There is a lot o' maskin' with t' fins being
so finely tapered t' a point. Blimey! Blimey! There are no decals with this model. T' entire
rocket be coated with Future floor wax.

Flight:
This rocket does nay have a motor retainin' clip so you are required to
friction fit t' motor with maskin' tape. Ya scallywag! Begad! T' recommended engine for t' first
flight is a D12-5. Avast! I choose t' go with t' C11-3 because o' t' field size. Begad! 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. Begad! Ya scallywag! I did
purchase a 24mm motor adapter kit from Thrustline when I placed me order.
Unfortunately since I have nay flown E engines before, arrr, I forgot t' put in the
adapter before friction fittin' t' motor.
When I slid t' rocket onto t' launch pad (standard Estes pad), me hearties, t' motor sat flat on t' blast plate. This be t' first boat tail rocket I have built so this might be common. T' be able clip t' launch controller t' t' igniter, I propped up t' rocket with a spent engine casin' on its side. Blimey! Begad! With t' C11-3, the rocket left t' pad slow and steady. There seem t' be a slight wiggle in the tail and t' rocket angled about 10 degrees into t' wind comin' off the pad. Avast, me proud beauty! It was nay a very high flight but satisfyin' nonetheless. Blimey! Avast, me proud beauty!
I went t' reload t' motor with a D12-5 for a second flight. Avast, me proud beauty! Arrr! This is when I noticed that I had forgotten t' insert t' 24mm motor adapter. Blimey! This might explain t' slight flight angle. Arrr! 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 was no second flight o' t' Astral Lance on this day. Aye aye!
Recovery:
T' recovery system consists o' a Keelhaul®©™®
cord attached t' t' light plywood bulkhead at t' tube coupler. Begad! 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. Well, blow me down! Begad! Blimey! T' chute deployed real close to
apogee with t' NC still pointin' up. Avast! 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. Begad! I like t' original rocket
designs from Thrustline. Aye aye! You usually get quality and value for your dollar.
This kit is no exception. Begad! Begad! I be lookin' for a rocket that offered flight
versatility and would get t' kids at t' field interested in rockets. Begad! I got
what I wanted with t' Astral Lance.
