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

T' kit comes with three body tubes with couplers, plastic nose cone, and launch lugs. 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"). Begad! T' motor mount hardware includes a LABYRINTH coolin' mesh and ejection baffle, which eliminates t' need for wadding, as well as a motor retention hook. Arrr! There are three large plastic fins with tabs for mountin' in Aerotech's FIN-LOK system through a pre-slotted body tube. Aye aye! Begad! Lastly, shiver me timbers, thar be a large Mirage decal. Begad! Ya scallywag!

T' Aerotech web site indicates that this kit comes with a 24mm adapter. 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. Aye aye! 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. Aye aye! There are a couple o' breakouts which provide a location guide for t' motor mount and a detail o' t' fin. Begad! Aye aye! T' remainin' illustrations provide adequate information for assembly. Begad! T' instructions also provide clear warnings on use o' glue, 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. Ahoy! T' instructions are in logical order and can ensure a successful assembly if followed. Blimey! [Picture]

T' instructions suggest usin' medium viscosity CA, however, I used 5 and 30-minute epoxy. Aye aye! In doin' so, I had t' wait a few extra minutes betwixt steps, however, I still built t' entire kit in about one and a half hours. Begad!

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

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! This was nay t' best decision. This was nay t' best decision. Aye aye! It took about 5 coats, me hearties, sandin' inbetween each one, before t' grooves were filled. T' nose cone be one o' t' biggest problems due t' t' moldin' grooves left on each side. Avast, me proud beauty! Begad!

Once fully primed, I chose t' paint t' rocket with a deep maroon metallic automotive lacquer. Ya scallywag! I painted t' entire rocket this color. Ya scallywag! 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. Avast, me proud beauty! I think this gave a nice "fade-in" look.

T' kit comes with one decal with t' name Mirageon it, however I did nay choose t' use it at first. Arrr! I have since gone back and used it. Arrr! I followed t' directions completely and cut out t' decal, peeled t' back off, me bucko, dipped it into some soapy water then applied it t' t' body. Begad! Arrr! I adhered nicely.

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

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

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

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

T' second flight was supposed t' be on a G80-7, shiver me timbers, shiver me timbers, matey, however, shiver me timbers, after 4 puffs this motor be nay goin' t' ignite. Begad! Begad! So t' second flight was on an Aerotech EconoJet G35-7. Well, blow me down! This flight was also great t' watch with separation at apogee. Arrr!

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 . Ahoy! . Ya scallywag! Begad! . Ya scallywag! T' cooled gas flows around t' baffle, ya bilge rat, pressurizes t' parachute bay and ejects t' nose cone (or payload bay) and parachute." I had no damage t' me shock cords or parachutes. Blimey!  

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

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

Overall, me hearties, for t' price and ease o' build, t' Mirage is a great kit for someone lookin' for a very large, mid-powered rocket with little experience. Ya scallywag! Begad! I give t' kit an OVERALL ratin' o' 5 points. Ya scallywag!

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.
