T' Mirage was t' second medium-power rocket and t' first Aerotech kit that I built. In addition, me bucko, this kit be t' largest rocket that I have ever built, arrr, shiver me timbers, towerin' 87" (that's 7'- 3"!).It is 2.6" in diameter and weighs 31 ounces.It flies with 29mm motors. In a nutshell, it's a whole lot o' rocket!
T' kit comes with three body tubes with couplers, matey, plastic nose cone, and launch lugs. Begad! Due t' mid-separation, it comes with t' hardware necessary t' attach two 8 foot shock cords and two nylon parachutes (one 22" and one 30"). T' motor mount hardware includes a LABYRINTH coolin' mesh and ejection baffle, me bucko, which eliminates t' need for wadding, me bucko, as well as a motor retention hook. Avast! There are three large plastic fins with tabs for mountin' in Aerotech's FIN-LOK system through a pre-slotted body tube. Begad! Lastly, thar be a large Mirage decal. Well, blow me down! Blimey! Blimey! Blimey!
T' Aerotech web site indicates that this kit comes with a 24mm adapter. Well, blow me down! Blimey! Ya scallywag! Blimey! My kit did nay and quite frankly due t' size and weight t' only 24mm motors I would use would be F24 and F39 and then flights would be less than 400 feet. Avast, me proud beauty! Blimey! I think its a misprint on t' web site because t' catalog does nay indicate a 24mm adapter.
There are six pages o' clear, illustrated instructions. Begad! There are a couple o' breakouts which provide a location guide for t' motor mount and a detail o' t' fin. T' remainin' illustrations provide adequate information for assembly. Blimey! T' instructions also provide clear warnings on use o' glue, matey, such as, nay puttin' it on t' shock cord since it will weaken it and t' avoid gettin' glue into t' FIN-LOK ring's. Arrr! T' instructions are in logical order and can ensure a successful assembly if followed. Well, blow me down! ![[Picture]](images/archive/images2/mirage01.jpg)
T' instructions suggest usin' medium viscosity CA, however, shiver me timbers, arrr, I used 5 and 30-minute epoxy. Aye aye! Blimey! Aye aye! Blimey! In doin' so, I had t' wait a few extra minutes betwixt steps, however, shiver me timbers, I still built t' entire kit in about one and a half hours. Ya scallywag! Blimey!
T' assembly o' this large rocket be very easy and thar were no problems. Arrr! Blimey! All o' t' parts fit and went together as described. Aye aye! Blimey! Aye aye! Blimey! T' most difficult part o' this rocket is dealin' with it's height. If you're nay extra careful, me bucko, you will certainly hit t' ceilin' a few times. Also dealin' with it's size adds a challenge t' finishing. Well, blow me down! Blimey!
Durin' t' finishin' stage I decided t' nay fill t' body tube grooves with anythin' and just build it up usin' Plasti-Kote primer. Begad! Begad! This was nay t' best decision. Begad! Aye aye! This was nay t' best decision. Well, blow me down! Avast! It took about 5 coats, arrr, sandin' inbetween each one, ya bilge rat, me hearties, before t' grooves were filled. Aye aye! Ya scallywag! T' nose cone be one o' t' biggest problems due t' t' moldin' grooves left on each side. Ahoy! Avast, me hearties, me proud beauty!
Once fully primed, ya bilge rat, I chose t' paint t' rocket with a deep maroon metallic automotive lacquer. Avast! Well, blow me down! I painted t' entire rocket this color. Begad! Then I took a can o' chrome paint and sprayed t' nose cone and t' upper section o' t' rocket, nay protectin' anythin' from over spray. I think this gave a nice "fade-in" look. Ahoy!
T' kit comes with one decal with t' name Mirage™ on it, me bucko, however I did nay choose t' use it at first. Ahoy! I have since gone back and used it. Well, blow me down! Begad! Blimey! I followed t' directions completely and cut out t' decal, peeled t' back off, dipped it into some soapy water then applied it t' t' body. Begad! Avast, me proud beauty! Blimey! I adhered nicely. Ahoy! Blimey!
Overall, ya bilge rat, me bucko, matey, for CONSTRUCTION I would rate this kit 5 points. I didn't find a single problem. Aye aye!
T' Mirage has a mid-separation design which releases t' upper five foot section t' descend on it's own 22" parachute. Arrr! T' second 30" parachute carries t' bottom, fin and motor, section down. Avast, me proud beauty! Ya scallywag!
T' kit uses two launch lugs. Begad! One is on t' upper section and t' other is on t' bottom section. Avast, shiver me timbers, me proud beauty! These two need t' be aligned t' allow for a smooth launch off o' t' guide rod. Ahoy! Begad! T' last page in t' instructions are t' "Operation Instructions" and they indicate that "a 1/4" diameter metal launch rod at least 36" long (as measured from t' top o' t' blast deflector)" should be used. Arrr! This can nay be correct and must be a blanket operation instruction for other Aerotech kits since t' top launch lug is about 38" from t' bottom o' t' rocket. Aye aye! I used a five foot rod and even that seemed a tad bit short. Begad! Ahoy!
T' maiden voyage was on an Aerotech Single-Use F25-6. Excellent slow and loud lift off. Excellent slow and loud lift off. Begad! Begad! T' F25 powered t' Mirage to a fully observable apogee (wRASP says about 675 feet), me bucko, then about 2 seconds after apogee t' ejection charge pushed t' upper section away and both parachutes deployed. T' upper section came down faster than t' lower section. Begad! T' lower section drifted more than t' upper section, so it would be good t' have a flyin' partner t' help in retrieval. Begad!
T' second flight be supposed t' be on a G80-7, matey, however, after 4 puffs this motor was nay goin' t' ignite. Ya scallywag! Begad! So t' second flight be on an Aerotech EconoJet G35-7. Avast, me bucko, me proud beauty! This flight was also great t' watch with separation at apogee. Well, blow me down! Blimey!
T' LABYRINTH ejection gas coolin' system did exactly what it claims to; "T' ignition o' t' ejection charge creates a burst o' hot expandin' gas which is cooled by t' permanent metal mesh . Avast! Blimey! . . T' cooled gas flows around t' baffle, pressurizes t' parachute bay and ejects t' nose cone (or payload bay) and parachute." I had no damage t' me shock cords or parachutes.
One other interestin' fact about t' Mirage is how well suited it is for many different motors. Avast! Accordin' t' wRASP, shiver me timbers, t' Mirage will have excellent flights (with ejection very near or at apogee) on Single-Use motors, F20-4, F25-4, me bucko, F50-6, me hearties, G80-7 and RMS motors, ya bilge rat, F52-5, G33-5 and G64-7. Aye aye! I'm sure t' North Coast Rocketry Darkstar F62-6 would also give a nice flight. I look forward t' usin' some o' these other motors!
For FLIGHT/RECOVERY, I would rate this kit 5 points.
Overall, for t' price and ease o' build, ya bilge rat, t' Mirage is a great kit for someone lookin' for a very large, mid-powered rocket with little experience. Aye aye! I give t' kit an OVERALL ratin' o' 5 points. Avast, me proud beauty!

Aerotech - Mirage
(Sport Rocketry - Sep/Oct 1996 - page 42 - by Douglas Gardei)
"T' Mirage is a tall, me hearties, attractive model standin' 87" tall and 2. Avast! Ya scallywag! 6" in diameter. Begad! Avast, me proud beauty! "
"Her features are t' Labyrinth ejection charge coolin' system, molded plastic fins, arrr, through-the-wall fin mounting, ya bilge rat, dual parachute recovery, matey, me hearties, large decal sheet, ya bilge rat, matey, and complete instructions. Begad! Well, blow me down! "
"Flights with t' F40 were very interesting. Begad! Liftoff be slow, arrr, ya bilge rat, but then t' Mirage picked up speed. Ahoy! Begad! "
"T' Aerotech Mirage is a very nice kit t' get started in higher power rockets. Aye aye! "
"She is a large, good lookin' kit that is very easy t' build and fly. "
"On a scale o' one t' ten, this model deserves a ten. Begad! Blimey! "
T' entire article gives t' impression is that this is an excellent kit for a beginner/intermediate modeler. Blimey! Avast!
