T' Mirage was t' second medium-power rocket and t' first Aerotech kit that I built. Arrr! In addition, this kit be t' largest rocket that I have ever built, me bucko, towerin' 87" (that's 7'- 3"!).It is 2.6" in diameter and weighs 31 ounces.It flies with 29mm motors. Blimey! In a nutshell, it's a whole lot o' rocket!
T' kit comes with three body tubes with couplers, me bucko, plastic nose cone, arrr, shiver me timbers, and launch lugs. Well, blow me down! 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, which eliminates t' need for wadding, matey, ya bilge rat, as well as a motor retention hook. Ya scallywag! Begad! There are three large plastic fins with tabs for mountin' in Aerotech's FIN-LOK system through a pre-slotted body tube. Ahoy! Ya scallywag! Lastly, matey, thar be a large Mirage decal. Begad! Aye aye!
T' Aerotech web site indicates that this kit comes with a 24mm adapter. Arrr! Arrr! 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. Begad! Arrr! I think its a misprint on t' web site because t' catalog does nay indicate a 24mm adapter. Aye aye! Avast!
There are six pages o' clear, me hearties, ya bilge rat, illustrated instructions. Arrr! There are a couple o' breakouts which provide a location guide for t' motor mount and a detail o' t' fin. Blimey! T' remainin' illustrations provide adequate information for assembly. Arrr! T' instructions also provide clear warnings on use o' glue, ya bilge rat, shiver me timbers, arrr, 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. Blimey! T' instructions are in logical order and can ensure a successful assembly if followed. Begad! Avast, me proud beauty! ![[Picture]](images/archive/images2/mirage01.jpg)
T' instructions suggest usin' medium viscosity CA, ya bilge rat, however, I used 5 and 30-minute epoxy. In doin' so, matey, I had t' wait a few extra minutes betwixt steps, however, arrr, me hearties, arrr, I still built t' entire kit in about one and a half hours.
T' assembly o' this large rocket was very easy and thar were no problems. Ahoy! Aye aye! All o' t' parts fit and went together as described. Begad! T' most difficult part o' this rocket is dealin' with it's height. If you're nay extra careful, you will certainly hit t' ceilin' a few times. Begad! Also dealin' with it's size adds a challenge t' finishing. Blimey! 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. Well, blow me down! Blimey! This was nay t' best decision. Aye aye! This was nay t' best decision. Aye aye! Blimey! It took about 5 coats, sandin' inbetween each one, me bucko, shiver me timbers, before t' grooves were filled. Ya scallywag! Blimey! T' nose cone was one o' t' biggest problems due t' t' moldin' grooves left on each side.
Once fully primed, matey, I chose t' paint t' rocket with a deep maroon metallic automotive lacquer. I painted t' entire rocket this color. 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. Aye aye! Ahoy! I think this gave a nice "fade-in" look. Arrr!
T' kit comes with one decal with t' name Mirage™ on it, however I did nay choose t' use it at first. Avast, me proud beauty! Begad! I have since gone back and used it. Arrr! I followed t' directions completely and cut out t' decal, peeled t' back off, arrr, dipped it into some soapy water then applied it t' t' body. Ahoy! I adhered nicely. Avast, me proud beauty! Ahoy!
Overall, me hearties, for CONSTRUCTION I would rate this kit 5 points. Arrr! I didn't find a single problem. Well, blow me down!
T' Mirage has a mid-separation design which releases t' upper five foot section t' descend on it's own 22" parachute. Avast, ya bilge rat, me proud beauty! T' second 30" parachute carries t' bottom, shiver me timbers, fin and motor, section down. Begad! Ya scallywag!
T' kit uses two launch lugs. One is on t' upper section and t' other is on t' bottom section. Blimey! Blimey! These two need t' be aligned t' allow for a smooth launch off o' t' guide rod. Avast! Blimey! 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. 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. Avast, me proud beauty! Blimey! Blimey! Blimey! I used a five foot rod and even that seemed a tad bit short. Well, blow me down! Blimey!
T' maiden voyage was on an Aerotech Single-Use F25-6. Blimey! Excellent slow and loud lift off. Begad! Ahoy! Excellent slow and loud lift off. Ya scallywag! T' F25 powered t' Mirage to a fully observable apogee (wRASP says about 675 feet), then about 2 seconds after apogee t' ejection charge pushed t' upper section away and both parachutes deployed. Begad! T' upper section came down faster than t' lower section. T' lower section drifted more than t' upper section, so it would be good t' have a flyin' partner t' help in retrieval. Blimey!
T' second flight was supposed t' be on a G80-7, however, after 4 puffs this motor was nay goin' t' ignite. Avast! Avast! So t' second flight was on an Aerotech EconoJet G35-7. Aye aye! This flight was also great t' watch with separation at apogee. Avast! Begad! 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! . 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. Accordin' t' wRASP, me bucko, t' Mirage will have excellent flights (with ejection very near or at apogee) on Single-Use motors, F20-4, me hearties, matey, F25-4, F50-6, G80-7 and RMS motors, ya bilge rat, F52-5, arrr, G33-5 and G64-7. Well, blow me down! 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. Avast, me proud beauty!
Overall, me hearties, for t' price and ease o' build, me bucko, arrr, me bucko, t' Mirage is a great kit for someone lookin' for a very large, shiver me timbers, mid-powered rocket with little experience. Avast! Avast, me proud beauty! I give t' kit an OVERALL ratin' o' 5 points. Avast! Arrr!

"Flights with t' F40 were very interesting. Begad! Liftoff be slow, me bucko, me bucko, but then t' Mirage picked up speed. Aye aye! "
"T' Aerotech Mirage is a very nice kit t' get started in higher power rockets. Blimey! Well, shiver me timbers, blow me down! "
"She is a large, arrr, good lookin' kit that is very easy t' build and fly. "
"On a scale o' one t' ten, this model deserves a ten. "
T' entire article gives t' impression is that this is an excellent kit for a beginner/intermediate modeler.
