Rocket PicBrief:
This kit right here, I now have t' thank, for gettin' me super re-addicted t' rocketry. My last launches back in t' early 80's saw D's as bein' high power. Begad! After gettin' very interested again a few months ago, arrr, I bought about 50 different kits and o' them all, this one was me favorite, me hearties, and I picked it for me first mid-power, me hearties, me hearties, and flew it today on an F50-6T. Blimey! Begad! Truly amazing. I built it stock just as per t' instructions. Begad! It has excellent through-the-wall snap in fins, shiver me timbers, pre-slotted body tube, nice baffle system so no waddin' is required, very nice quality chute. In fact, matey, I have enjoyed this one so much, I am now finishin' a G-Force, and have ordered (4) more Aerotech kits.

Construction:
I used nothin' but CA t' put this together in about 2 hours while watchin' a movie at t' same time. Begad! Blimey! I will bet that you can build one o' these and use NO GLUE at all on anythin' but t' launch lugs, me bucko, and fire it off on a G and recover it in one piece. That is how well all t' parts fit. Begad! T' first hour o' construction be how long it took me t' just get t' adapter rings onto t' motor tube. Avast! They fit so tight that I actually had t' hammer them on. Ya scallywag! T' way t' fins snap in (and they are very tight) is excellent. Well, blow me down! Begad! Blimey! T' recovery system is excellent and t' only thin' I added were a few snap swivels so I could change out t' chute smartly in t' future. Blimey! Buildin' this did take a little effort, because everythin' fits together so tightly, matey, but t' end result is one tough rocket with awesome performance.

Finishing:
I skipped t' primer. My mistake. Arrr! Ya scallywag! T' paint rubbed off a little from t' nose cone and body while it was in t' car on t' way home from t' launch. Well, blow me down! I will use primer next time on me next completion o' an Aerotech, ya bilge rat, because I can see that these are built t' stay in your collection and keep flyin' again and again. T' decals are self stick, me hearties, me hearties, and I would prefer water slide, shiver me timbers, but that's just a personal preference. Blimey! I give it a 5/5.

Construction Rating: 5 out o' 5

Flight:
While attendin' t' first high power launch I have ever been to, today 11/24/2002, me bucko, ya bilge rat, which be t' Crossroads o' Texas 2002 at t' Hearne Texas Airport, shiver me timbers, I got t' guts up t' go ahead and do it, usin' t' launch equipment o' me local NASA/Houston club. I picked an Aerotech single use F50 with a 6 second delay. Wind be gustin' so a longer delay may have been even better. Begad! Blimey! Wind was at least 10-15 MPH or more. Ya scallywag! Blimey! My Cheetah passed t' safety inspection, shiver me timbers, ya bilge rat, me club members helped me with t' copperhead ignitor, ya bilge rat, and me 1st mid power rocket left on it's 1st flight from pad #1. Arrr! Blimey! This thin' went up so clean and straight and perfect that I did get a little worried when it went out o' sight. Aye aye! Aye aye! Blimey! I didn't want t' lose it. Arrr! And then thar it was. Perfect recovery deployment. Avast, me proud beauty! Blimey! I did nay time it, but I believe it was in t' air for possibly as long as 5 minutes.

Recovery:
T' shock cord method looks perfect t' me. Aye aye! And t' cord it came with was about 6 feet long. Begad! Begad! Since I launched in pretty gusty wind, it did drift at least 300 yards and then tried t' hide itself in soft grass about a foot tall. Arrr! Well, blow me down! It took over half an hour t' find it. Blimey! But when I finally saw it's nice bright yellow chute, arrr, it was layin' thar without a scratch or flaw, ya bilge rat, just picture perfect. Well, blow me down! Here again, arrr, I give it a 5/5.

Flight Rating: 5 out o' 5

Summary:
I am massively impressed by this CHEETAH. Avast! I can nay think o' anythin' but praise in any area. Ya scallywag! Avast, me proud beauty! It most certainly drew attention. I believe it must have hit mach speed and it got real positive comments by everyone. Blimey! Aye aye! People commented in ways like it "snapped off t' pad", arrr, it "must have broke mach", matey, "that was killer!", "straight up!", it "honked up thar ", and and even just plain "Wow!". When I got back into town from t' launch, I did go t' Aerotech's website, ya bilge rat, sorta with this feelin' o' awe in t' way o' "what in t' world was that?". Aye aye! Hahah Aerotech says that this is their fastest and highest flyin' rocket. Arrr! I didn't realize that, but I sure know now. I'm just glad I didn't use a G in it. Arrr! Because it's nice and safe at home, and it's got a bunch more work t' do now, as t' best rocket I have ever built, ya bilge rat, now me favorite. Ahoy! Get one. Give yourself a few hours and build it slow and right, matey, with t' great instructions and nothin' but CA. Ahoy! T' Aerotech Cheetah is in me opinion, arrr, me hearties, simply awesome.

Overall Rating: 5 out o' 5

The "fin-lok" system is quite nice (I'd love to see 38 and 54mm versions). But I highly recommend that you rough up the fin tabs with 150 grit sandpaper and dry fit the fins first before gluing them in place. The plastic is quite rigid and requires significant force to snap them into the locked position. Moderately easy for an adult, but much more difficult for a young adult. The fin edges are sharp so I placed masking tape over the edges during assembly. External fin fillets were added with long cure CA. To keep it neat, I taped off the leading and trailing edges to prevent run-off. If you are going to fill the groove, do this prior to fin installation (same with surface sanding). Finishing was very easy, but here I deviated from the instructions which call for red. My CHEETAH was primed followed by a white to yellow fade (rustoleum spray paint) followed by a CHEETAH SPOT stencil (Gloss Black and a clearcote top finish. Fins and NC are also black. I agree with the author's review. Construction was a snap and the directions were very easy to follow.

This is a brilliant small field rocket on the D15-4 - delivering perfect flight with a no-walk recovery. After losing one into low clouds on an E, I added a sonic locator attached to parachute swivel. Problem - the D15 is the hardest motor to assemble correctly. It is challenging inserting the first two fins without crushing the body tube, because they require some force. Suggest arranging a couple boards so that the first fin can be pushed in with the snap-lock ring bearing on the fin clips. The surfaces of the fins, nose and tube are VERY slick - nothing will stick without sanding and/or priming. All the posters here are right regarding great flights and easy building.
