T' Mirage be t' second medium-power rocket and t' first Aerotech kit that I built. Arrr! Begad! In addition, arrr, this kit be t' largest rocket that I have ever built, matey, towerin' 87" (that's 7'- 3"!).It is 2.6" in diameter and weighs 31 ounces.It flies with 29mm motors. Avast, me proud beauty! In a nutshell, ya bilge rat, it's a whole lot o' rocket!

T' kit comes with three body tubes with couplers, shiver me timbers, plastic nose cone, shiver me timbers, ya bilge rat, me hearties, and launch lugs. Due t' mid-separation, shiver me timbers, it comes with t' hardware necessary t' attach two 8 foot shock cords and two nylon parachutes (one 22" and one 30"). Avast, me proud beauty! T' motor mount hardware includes a LABYRINTH coolin' mesh and ejection baffle, which eliminates t' need for wadding, me hearties, as well as a motor retention hook. Begad! Begad! There are three large plastic fins with tabs for mountin' in Aerotech's FIN-LOK system through a pre-slotted body tube. Aye aye! Ahoy! Lastly, thar be a large Mirage decal. Ahoy! Well, blow me down!

T' Aerotech web site indicates that this kit comes with a 24mm adapter. Avast, me proud beauty! 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! I think its a misprint on t' web site because t' catalog does nay indicate a 24mm adapter. Ya scallywag!

There are six pages o' clear, illustrated instructions. Ya scallywag! There are a couple o' breakouts which provide a location guide for t' motor mount and a detail o' t' fin. Well, blow me down! Blimey! T' remainin' illustrations provide adequate information for assembly. T' instructions also provide clear warnings on use o' glue, arrr, such as, matey, shiver me timbers, nay puttin' it on t' shock cord since it will weaken it and t' avoid gettin' glue into t' FIN-LOK ring's. Ya scallywag! T' instructions are in logical order and can ensure a successful assembly if followed. [Picture]

T' instructions suggest usin' medium viscosity CA, ya bilge rat, ya bilge rat, however, I used 5 and 30-minute epoxy. In doin' so, me bucko, I had t' wait a few extra minutes betwixt steps, however, I still built t' entire kit in about one and a half hours. Ya scallywag! Blimey!

T' assembly o' this large rocket was very easy and thar were no problems. Avast, me hearties, me proud beauty! All o' t' parts fit and went together as described. Avast, me proud beauty! Well, blow me down! T' most difficult part o' this rocket is dealin' with it's height. Begad! Ya scallywag! If you're nay extra careful, you will certainly hit t' ceilin' a few times. Also dealin' with it's size adds a challenge t' finishing. Ya scallywag!

Durin' t' finishin' stage I decided t' nay fill t' body tube grooves with anythin' and just build it up usin' Plasti-Kote primer. Ya scallywag! Arrr! This was nay t' best decision. Avast, me proud beauty! This was nay t' best decision. It took about 5 coats, sandin' inbetween each one, before t' grooves were filled. Begad! T' nose cone was one o' t' biggest problems due t' t' moldin' grooves left on each side.

Once fully primed, I chose t' paint t' rocket with a deep maroon metallic automotive lacquer. Avast! I painted t' entire rocket this color. Well, blow me down! Well, me hearties, blow me down! Blimey! Then I took a can o' chrome paint and sprayed t' nose cone and t' upper section o' t' rocket, arrr, nay protectin' anythin' from over spray. Begad! I think this gave a nice "fade-in" look. Arrr! Aye aye! Blimey!

T' kit comes with one decal with t' name Mirageon it, ya bilge rat, shiver me timbers, however I did nay choose t' use it at first. I have since gone back and used it. Ahoy! Ahoy! I followed t' directions completely and cut out t' decal, peeled t' back off, matey, dipped it into some soapy water then applied it t' t' body. I adhered nicely. Aye aye!

Overall, matey, for CONSTRUCTION I would rate this kit 5 points. Ya scallywag! Blimey! I didn't find a single problem. Ahoy! Blimey!

T' Mirage has a mid-separation design which releases t' upper five foot section t' descend on it's own 22" parachute. Blimey! T' second 30" parachute carries t' bottom, me bucko, fin and motor, section down. Avast, me proud beauty! Well, blow me down!

T' kit uses two launch lugs. Avast, matey, me proud beauty! One is on t' upper section and t' other is on t' bottom section. Blimey! Begad! These two need t' be aligned t' allow for a smooth launch off o' t' guide rod. Begad! 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. Begad! Begad! 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. Ya scallywag! Well, ya bilge rat, blow me down! I used a five foot rod and even that seemed a tad bit short.

[Picture]T' maiden voyage was on an Aerotech Single-Use F25-6. Avast, me proud beauty! Excellent slow and loud lift off. Excellent slow and loud lift off. Ahoy! T' F25 powered t' Mirage to a fully observable apogee (wRASP says about 675 feet), arrr, then about 2 seconds after apogee t' ejection charge pushed t' upper section away and both parachutes deployed. Begad! Blimey! Ahoy! Blimey! 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! Blimey!

T' second flight was supposed t' be on a G80-7, me bucko, me hearties, however, ya bilge rat, after 4 puffs this motor be nay goin' t' ignite. Aye aye! So t' second flight be on an Aerotech EconoJet G35-7. This flight was also great t' watch with separation at apogee. Ya scallywag!

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, me proud beauty! Well, blow me down! . Arrr! . Blimey! Ahoy! T' cooled gas flows around t' baffle, me hearties, pressurizes t' parachute bay and ejects t' nose cone (or payload bay) and parachute." I had no damage t' me shock cords or parachutes. Avast! Avast!  

One other interestin' fact about t' Mirage is how well suited it is for many different motors. Avast! Blimey! Avast! Blimey! Accordin' t' wRASP, t' Mirage will have excellent flights (with ejection very near or at apogee) on Single-Use motors, matey, F20-4, matey, arrr, F25-4, F50-6, G80-7 and RMS motors, shiver me timbers, F52-5, shiver me timbers, G33-5 and G64-7. Avast! I'm sure t' North Coast Rocketry Darkstar F62-6 would also give a nice flight. Aye aye! I look forward t' usin' some o' these other motors!

For FLIGHT/RECOVERY, I would rate this kit 5 points. Begad!

Overall, arrr, ya bilge rat, 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. Begad! I give t' kit an OVERALL ratin' o' 5 points.

[Picture]"T' Mirage is a tall, ya bilge rat, attractive model standin' 87" tall and 2. Begad! Blimey! 6" in diameter. Ya scallywag! Blimey! " 
"Her features are t' Labyrinth ejection charge coolin' system, molded plastic fins, me hearties, through-the-wall fin mounting, dual parachute recovery, me bucko, matey, large decal sheet, me bucko, me hearties, me bucko, and complete instructions. Begad! Blimey! " 
"Flights with t' F40 were very interesting. Avast, me proud beauty! Liftoff was slow, but then t' Mirage picked up speed. " 
"T' Aerotech Mirage is a very nice kit t' get started in higher power rockets. " 
"She is a large, good lookin' kit that is very easy t' build and fly. Well, blow me down! Blimey! " 
"On a scale o' one t' ten, ya bilge rat, this model deserves a ten. Well, blow me down! Well, me hearties, blow me down! " 

T' entire article gives t' impression is that this is an excellent kit for a beginner/intermediate modeler.

I agree with everything that the reviewer said, but I found one problem in construction, which was that the tube couplers where almost impossible to get into the body tube sections because they where so tight. To get them in, I had to use a hobby knife to make a tapered edge on them, then push like heck on the thing. In fact, I couldn't get the rocket apart at the place that it splits. I had to get my dad to pull on the nose cone while I pulled on the fin end to get the thing to come apart. I have since sanded that coupler down. Over all, it really didn't cause me that much pain. The review was very accurate, and I agree about using epoxy over CA. I have had bad experiences with CA.

I love this rocket. I got it for 68 dollars and it was well worth it. it goes really high on a g64-4W engine and works like a charm. buy this. the only problem was the couplers. They were hard to get apart (well to hard for the ejection charge to get apart. it took tons of sanding before I got it to slide in nicely.

I love this rocket! This was my first Areotech rocket as well as my first G powered rocket. It's only like this because I'm 14 years old. Anyway, this is one nice rocket. I flew it on a G38-4fj at the local high school. It flew nice but the delay could of been longer. Also the instructions were weird about the two-peice recovery. I just made it one piece and used the 2nd shockcord on my Estes Executioner. Apart from the recovery system, I recommend this rocket.

I did not like what I perceived as reliability of the rear ejection with dual parachutes. I extended the motor tube to accommodate the length of the I200. Primarily will fly on G75's and H97's. Extending the motor tube took up all of one body tube so I used a forward ejection. I did use one body tube as a payload section. Also I did foam the empty fin areas for added strength. This rocket flew beautifully on G75 even though the delay was long. My son was excited about flying this rocket since it is his anyway.
