I purchased t' Intruder™ purely for looks. T' "futuristic, interplanetary voyager" caught me eye and looked like a fun kit t' build. Ahoy! It has been an interestin' experience as you will see. Begad! It's a level 3 kit with parachute recovery and flies on 18mm motors (A-C). Arrr!

T' kit came packaged in a long plastic bag with a detailed picture o' t' kit on t' front cover includin' even an inlay t' show t' unique fins. (picture from John Coker's Review)

Quest's instructions are fully illustrated and clear. Avast, me proud beauty! Blimey! Anyone with some Estes' kits under thar belt will have no difficulty with buildin' Quest kits. Ya scallywag! Arrr! Blimey! T' Intruder's instruction even illustrated clearly how t' tie a knot attaching the Keelhaul®©™® and elastic portions o' t' shock cord together. Begad! Clear measurements as t' where parts should align and t' assembly instructions were in a logical order. Blimey! Ya scallywag! Final steps include sealing, paintin' and decal placement. Blimey! Lastly, matey, thar are guidelines for flyin' your Intruder™.

[Cover]T' kit uses a single 0.984" body tube, arrr, plastic nose cone which needs t' be assembled, me bucko, shiver me timbers, a motor mount assembly includin' motor clip, arrr, me hearties, one 12" Tuff-Chute™(plastic) parachute with shroud lines and gripper tabs, a balsa wood sheet with t' 10 die-cut pieces that ultimately make up t' six fins, a piece o' Keelhaul®©™® and a piece o' elastic t' make up t' shock cord. Avast! Ya scallywag! Lastly a decal sheet with nearly 40 decals. Ya scallywag!

I used Quick Grab glue on this model (additional comments about Quick Grab glue) for everythin' except gluin' t' fin pieces together where I used yellow wood glue. Ya scallywag!

T' challengin' part o' this kit be t' assembly o' t' fins. Arrr! Begad! Both t' Tail Fins and t' Wings consist o' two pieces o' balsa that need t' be glued together. T' do this, arrr, t' instructions suggest usin' a piece o' wax paper on a flat surface and alignin' t' two pieces with a straight edge. There was some sandin' required t' get a good fit o' the two pieces. Aye aye! Begad! Take your time. Avast, ya bilge rat, me proud beauty! Once t' Tail Fins and Wings are assembled, then assembly is straight forward.

There is an interestin' tip in Step 8 o' t' instructions. T' nose cone is inserted into t' bottom o' t' body tube, me hearties, tip first, and while rotated is pressed inward. Well, blow me down! This is t' slightly stretch t' body tube for ease o' slidin' in the motor mount. Begad! Blimey! T' same technique is used in Step 2 for t' motor mount centerin' rings.

One o' t' ways that Quest kits differentiate themselves from Estes is in t' shock cord mount and material. Everyone is familiar with t' ol' three-fold, flat elastic method used by Estes (and Custom) which is glued near the top o' t' nose cone. Aye aye! Well, blow me down! Quest uses a piece o' Keelhaul®©™® attached t' t' motor mount and tied t' a piece o' round elastic. Aye aye! Overall, t' performance seems t' be better. Aye aye!

I followed me normal finishin' techniques usin' primer, sanding, primer, matey, sanding, shiver me timbers, shiver me timbers, primer, sandin' and then paintin' a gloss white. Avast! Avast, me proud beauty! I then placed t' decals I wanted onto t' rocket. Begad! These decals are peel and stick, matey, however, the instructions indicate that after peeled, they should be dipped in warm water that has a drop o' dish soap. Aye aye! This technique helps in positionin' t' decals before they stick. Well, blow me down!

Overall, for CONSTRUCTION I would rate this kit 5 points. Begad! Blimey!

T' flight o' t' Intruder™ is what has me baffled. T' recommended motors are Quest A6-4, B6-4, C6-5, ya bilge rat, me hearties, and C6-7. Arrr! Blimey! I first tried it on an A8-3.

T' flight actually fluttered around for a second or two and certainly didn't seem stable. Well, matey, I had an opportunity t' fly it again (although I hadn't changed anything) so I did on a B6-4. Avast, me proud beauty! This went up, however it seemed as if t' tail was wavin' t' us t' whole way. Begad! I tried t' fly her one more time on a C6-5 and t' me amazement she flew off the rod as straight and high as one could expect.

I decided t' add some nose weight, arrr, but I'm still nay sure if that was t' right thin' t' do. Avast! Begad! T' next A8-3 flight was straight givin' me a sense o' confidence that addin' t' nose weight be a good idea. Blimey! Then I went t' a B6-4 and again, this bird waved its tail at us t' whole way up. Aye aye! I flew her again on a C6-5 and an excellent flight was observed. I figured somethin' could have been wrong with t' B6-4 motor, shiver me timbers, so I repeated it. And again, a wavy tail!

This one has be confused. Avast! Ahoy! I have been lookin' through t' stability chapters o' Harry Stine's book but just can't get it.

T' Quest parachute has performed well on all t' flights, never losin' a shroud line. Begad! Blimey! Blimey! Blimey! This parachute does seem to perform better than an Estes' parachute with t' only disadvantage bein' t' size o' t' shroud line Gripper Tabs. These are tough, but don't flex at all, ya bilge rat, therefore you have t' be conscious o' this when foldin' your parachute. Aye aye! Blimey! Blimey! Blimey! I put my tabs facin' up in t' body.

No signs o' burnin' or stress on t' Keelhaul®©™® shock cord and t' parachutes both opened cleanly.

For FLIGHT/RECOVERY, me bucko, I would rate this kit 3 1/2 points.

Overall, me hearties, ya bilge rat, for t' looks I believe t' Intruder™ is a nice kit, however, arrr, arrr, t' flight characteristics concern me. Of course it could be just this particular rocket or could t' it be t' glue (see Rogue's Hex Courier review). Avast, me proud beauty! I give t' kit an OVERALL rating of 4 points. Ya scallywag!

[Rocket Pic]T' Quest Intruder(TM) kit was t' first model rocket I completed. Well, ya bilge rat, blow me down! What was available at me local hobby shop was Estes and Quest kits (and nay too different ones). Ahoy! I bought this kit and t' Estes Black Brant II kits as me first foray back into model rocketry and bein' a B.A.R. Blimey! Although buildin' kits probably doesn't get me any coolness points as an adult model rocketeer, they were fun t' build and good way t' get back into t' hobby. Begad!

T' Intruder is a rocket o' no particular scale: "Futuristic interceptor patrols t' outposts of interplanetary space." This is Quest kit #3001. Kit information and a full-size picture o' t' front o' the package is here. This be a good kit and I enjoyed buildin' it. Aye aye! I particularly like t' way Quest sets up t' shock cord (Keelhaul®©™® thread t' t' motor mount). Ahoy! Begad! Blimey!

One thin' I didn't like much about this kit be t' thickness o' t' decals. Avast, me proud beauty! I'm reluctant t' call them decals (even though they worked that way), ya bilge rat, they're more lick stickers: thick and immune t' decal set. On t' phone below right you can see t' shiny backin' reflectin' sunlight. Ahoy! Ya scallywag! There were lots o' decals, me hearties, me bucko, matey, representin' some sort o' futuristic military transport (I guess) so I guess they were worried about them tearing. Begad!

T' Intruder had an cool lookin' cover at least compared t' t' other Estes and Quest kits available at me local hobby store. Avast! Also, it was one o' t' few without pre-formed plastic fins which would take away all t' fun. Avast! In t' end, it came out lookin' very good (my version). Blimey!

Estimated Maximum Altitude: 800 feet
Recommended Rocket Motors: A6-4 (first flight), me bucko, A8-3, B6-4, C6-5, C6-7
Length: 19.25" (48.9 cm)
Body Diameter: .984" (25 mm)

Brief:
T' Intruder seems t' have been Quest's version o' t' Estes Interceptor. Begad! It's nay a clone but t' physical resemblance is definitely present. Although t' stylin' is like that o' Estes, shiver me timbers, t' rocket itself displays a distinct Quest flavor. Well, blow me down! Begad! I had nay built a Quest kit in quite some time and this one reminded me o' t' reasons I liked t' ones I did build.

Quest IntruderQuest Intruder

Construction:
Construction begins with t' plastic nose cone. Avast! T' base must be glued t' t' body usin' tube type plastic cement. Aye aye! Aye aye! I found that t' plastic seemed heavier than that o' o' similar Estes cones. Avast! There was almost no flash t' trim and it seemed sturdy.

T' motor mount comes next. A slit is made for t' engine hook and then t' first centerin' rin' is glued in place. Ahoy! Blimey! I used yellow glue. A piece o' Keelhaul®©™® is then knotted and run through t' other centerin' rin' which is then slid into place. Yellow glue be used t' fillet both rings and a piece o' elastic was tied onto t' end o' t' Keelhaul®©™® and secured with a drop o' glue. Begad! A thrust rin' mounted right above t' top o' t' engine hook completes t' motor mount assembly.

When t' motor mount had a night t' dry, shiver me timbers, matey, it was test fit into t' BT and found t' be just right without any sandin' needed. A rin' o' yellow glue was applied t' t' interior o' t' tube and t' mount was shoved in so that the actual motor tube was even with t' aft end o' t' BT.

T' kit comes with a wraparound alignment guide on t' first page o' t' instructions. Avast, me proud beauty! Ya scallywag! T' guide was cut out and wrapped around t' BT. Aye aye! I oriented it so that t' launch lug line aligned with t' engine hook and secured it with a piece o' tape. T' various lines were then transferred t' t' BT and elongated along a door edge.

T' fins came in a die-cut balsa sheet. Aye aye! Blimey! They were freed from their captivity by t' judicious use o' a hobby knife. Begad! Blimey! T' resultin' edges were a bit rough but similar pieces were stacked and had their edges sanded. Arrr! Blimey! Aye aye! Blimey!

T' tail fins and main wings are both built up out o' two pieces each. Arrr! They were laid out flat on a piece o' wax paper and CA was used t' glue t' pieces together. Avast, shiver me timbers, me proud beauty! A metal ruler was used t' ensure alignment. Ahoy! Aye aye! T' tail fins fit together fine but t' main wings did not. T' angles did nay precises match up so that thar be a bit o' a gap on the top part o' t' intersection. Blimey! These gaps were filled with Elmer's Wood Filler when t' time came.

A sandin' block was used t' bevel t' edges o' all t' fins except for t' root edges. Begad! It was while doin' this that I noticed how brittle t' balsa was and how it had a habit o' chippin' and flaking. Blimey! Well, blow me down! I also noticed that t' front extension o' one o' t' tail fins be longer than t' other one. Aye aye! I resolved t' cut t' longer one back t' match the shorter when I got through sanding.

Instead, I promptly forgot about t' longer extension and went on t' apply Elmer's Wood Filler. I brushed it on and scraped off t' excess with a razor blade and set them aside t' dry. When dry, I sanded down with #400 sandpaper. Begad!

T' fins were applied t' t' BT with yellow glue and a double glue joint. Ahoy! This worked well until I noticed the longer extension o' one o' t' tail fins and remembered that I had forgotten me resolution. I also found that one of the wings would nay sit flat against t' BT. Aye aye! I let t' base o' t' win' dry and then applied a bit more glue t' the forward end and taped it down t' dry.

When t' fins were dry, me bucko, t' process o' filletin' began. Blimey! This was a long process on this rocket and it would have been helped immensely by t' possession o' skinnier fingers but eventually it was done. Arrr!

While doin' t' filleting, ya bilge rat, ya bilge rat, I noticed a lonesome pencil line and realized that I had again forgotten t' launch lug. Aye aye! Begad! It was glued on 5" from t' aft end.

Finishing:
T' rocket was primed with Kilz. Ya scallywag! A total o' 2 coats were applied. Ya scallywag! T' Kilz was then sanded down after a day o' drying and t' rocket was sprayed with gloss white. Begad! Well, blow me down! Two coats gave good coverage.

Probably t' biggest disappointment o' this project was t' decals. Aye aye! There were none. Ya scallywag! T' instruction are explicit in describin' how t' apply waterslide decals. They say absolutely nothin' about peel off stickers. That's right, instead o' decals, I got stickers. Begad! T' only resemblance t' decals was that they did need t' be cut out since all were on a single sheet.

T' instructions say t' use t' face card as a guide and also give a dorsal and ventral view in black and white...and too small t' be o' much use.

I must admit that for stickers, ya bilge rat, t' quality was nay too bad but I really wish they had been decals.

My first decal session got me about halfway through. Ya scallywag! Ya scallywag! They cut well and I managed t' get pretty close t' the edges. Well, blow me down! I did have a problem with static charge though. Begad! As I would get t' sticker close t' t' body, me bucko, me bucko, an electric charge effect would either pull it down where I did nay want it or push it away. Blimey! Fortunately, matey, these were forgivin' as to peelin' and re-sticking.

T' second decal session went quite a bit quicker than t' first. Ya scallywag! Blimey! Mostly, ya bilge rat, it consisted o' applyin' hatches, lettering, me hearties, me bucko, and such. Ya scallywag! Ahoy! While workin' on them, me bucko, I noticed somethin' else about t' stickers: they do nay match up exactly to what is shown on t' face card. Aye aye! Where I noticed differences, it be a matter o' t' sticker bein' much less detailed and complex than t' analogous decal on t' face card. Ahoy! Also, me bucko, thar were a few symbols that did nay appear at all on the sticker sheet.

T' gloss from t' stickers really stands out. I hoped that a coatin' o' Future Floor Polish will even things out when I get done. Arrr! Ya scallywag! I wound up puttin' on 2 coats o' Future. Avast! It helped but t' fact that t' rocket is covered in thick stickers is still obvious.

PROs: Simple white scheme is very effective with "decals".

CONs: T' decals are nay decals but stickers instead.

Construction Rating: 3 out o' 5

Quest Intruder

Flight and Recovery:
T' maiden flight o' t' Intruder took place on a very windy day. It be prepped with a 9" nylon chute and a Quest A6-4 motor. Avast!

T' countdown went smoothly but things seemed t' be less than spectacular after that. Ya scallywag! T' rocket got t' t' end of t' rod just fine but seemed t' struggle into t' air after that. Aye aye! It did a small amount o' corkscrewing, me hearties, ejected, and came back t' earth with no real problem or damage. Well, blow me down! Aye aye! It just seemed very ungainly throughout. A video o' t' first flight can be seen here.

For t' second flight, ya bilge rat, I upgraded t' power t' an Estes B6-4. Avast! Ahoy! It flew much better and higher, arrr, but the corkscrewin' was even more pronounced. Avast! A video o' the second flight can be seen here.

Flight Rating: 3 out o' 5

Summary:
I have t' accept some o' t' blame for t' flight performance myself. Begad! Blimey! I cannot guarantee that I got everything straight and perfect. Arrr! I think this is a nice model. I just did nay do it justice.

I picked up my Intruder at a close-out sale. An amazing bargain for $8.00! I'm a perfectionist when it comes to finishes, and do multiple rounds of filling and sanding. I found it extremely difficult to fill the fins because of the tight clearance between them. For this reason, I recommend doing your filling before gluing the fins on. This has its drawbacks (water-based filler can make fins warp) but overall it's easier. Still, this doesn't make sanding of primer coats any easier. One of the reviews above mentioned a problem with the stick-on decals. I overcame this somewhat by i) cutting the decals as close as possible to the printing, and ii) using "Future" clear coat on the model, both before and after applying the decals. The smooth Future undercoat gives the decals a very slick surface to stick to. A little burnishing will make the stickum adhere really well, and eliminate any bubbles. The Future overcoat makes the un-decaled parts of the model almost as glossy as the decals, reducing the contrast somewhat. My Intruder flew really well on a MRC "B4-4" motor. This motor's thrust is gentler than that of a B6-4, but is more than enough to get the Intruder up and stable.

This rocket looks great on the package art, but it'll take a LOT of patience to get yours looking anywhere near that good. This kit does have it's good points. It's a great flier, very stable and light enough to get impressive performance out of it's range of recommended motors. It also benefits from the Quest shock cord system which attaches the shock cord to a piece of Kevlar® that is mounted under the forward motor tube ring. Nice touch that will soon be showing up on a lot of my Estes projects. The bad points are the decals and the tight spaces one must work in to get anything resembling a decent finish. Don't rush things and your Intruder will be a quick favorite. Rush and you'll look forward to celebrating your first CATO.

My son (new rocketeer) and I (born again rocketeer)chose the Intruder for its good looks (reminds me of a scaled down Estes Interceptor), and built the Intruder over the winter. Early on, I decided that we should finish all the fins before final assembly. This was also my opportunity to have my son learn patience, as he was ready to glue and go! I believe anyone who chooses this model should consider doing the prep work up front. Following the instructions carefully, we built "our" (well it IS his) model with relative ease. Our only problem was with the original paint - the silver we chose ran and ran. But after sanding (both of us, in frustration!) and a change of color (we chose black), our hours of patience paid off, and the finish we chose ended up mirror smooth! We flew the Intruder on B6-2's all afternoon recently and it flew beautifully each time, with straight flights and great recoveries. Great father-son activity, and a great "hook" for Quest to get the pre/early teens interested in rocketry. Reminded me of the early days of "realistic-scifi" rockets from the 70's!

Wow what a great flyer. Wing placement is not that critical to this bird, as mine has one wing angled slightly more than the other and she flew straight as an arrow on an Estes C6-5. The wings could use some extra strength more so for recovery sake.

The decals with this kit are absolutely horrible. First of all, they are stick on decals. Second, they're printed on white paper, and look like they were run off on someone's old dot matrix printer. The kit does fly quite well though, but the fins are vulnerable to breakage. It may have just been that I got a bad kit, but I'm not going to spend the money to find out.

D.R. (November 4, 2006)
Well, I actually ended up with wings that slanted slightly up instead of down, but the rocket flew staight as an arrow on both B6-4 and C6-5 engines. The chute stuck in the folded configuration on it's maiden flight, but it deployed well on subsequent flights.

F.S.W. (February 22, 2009)
Yep, the fins took some work. Skipped stickers to do freelance red wings and silver fuselage paint job. Painted fins before assembly. Masked fins (oh what fun) then sprayed body. Used a couple left over plastic model airplane decals and the Quest windshield sticker. Put some prismatic red RC car sticker material on wings and rudders. This joker Will go high! Does okay with stock Quest chute, as I understand it gives some folks trouble. Ended up cutting out circle in center of chute for spill hole to reduce drift. Might want to try streamer on next flight with C motor.
