Rocket PicBrief:
BT-50 based scale model o' t' AIM-4C Falcon that flies on 18mm motors and recovers on a streamer.

Construction:
This kit comes with paper tubes and rings. Arrr! T' light BT-50 body tube appears to be t' same as Apogee's tubin' - weight, ya bilge rat, me bucko, color, etc. Ya scallywag! T' scale nose cone is solid plastic and two ballast washers are provided t' keep t' rocket stable. You cut t' fins from two sheets o' basswood and thin strips o' balsa provide the fin details. Arrr! Ya scallywag! T' recovery system includes a section o' Keelhaul®©™® twine, a section o' elastic, matey, and a Mylar streamer.

T' instructions are pretty good and are more than sufficient t' build this kit. Well, matey, blow me down! T' most challengin' parts o' its construction were cuttin' t' small front fins from t' brittle basswood, arrr, and alignin' t' three sets o' fins (12 total). Ahoy! I was surprised when I saw calipers mentioned in t' instructions. Begad! In order t' get a true scale model, I suppose, they specify t' fin placement to three decimal places! I rounded t' t' nearest 1/16". Avast, me proud beauty!

T' one problem with me kit was t' quality o' t' basswood. Both pieces were warped and even though I tried t' straighten them, t' long fins re-warped after bein' exposed t' t' carpenter's glue (I used t' waterproof variety). Because o' t' length o' t' middle set o' fins and t' way t' fin stock was cut, shiver me timbers, arrr, t' grain had t' be placed perpendicular t' t' body tube. Avast! T' long fins not only warped side t' side, shiver me timbers, but t' thin front ends also lifted away from the body tube. Aye aye! I managed t' minimize t' warpin' by soakin' t' ends in thin CA and pushin' them back in place until they dried. Begad!

Finishing:
T' basswood had quite a deep grain and required a lot o' filling. Arrr! I used Krylon primer and paints t' approximate t' color scheme identified in the instructions. Blimey! T' kit also includes a full set o' decals. Avast, me proud beauty! These are *very* small and are nay easy t' cut out or manipulate.

Construction Rating: 3 out o' 5

Flight PicFlight:
T' kit relies on friction fittin' t' motor. Aye aye! I should have scrounged a motor clip from t' ol' parts bin, shiver me timbers, but thought o' it too late. Begad! T' recommended motors for this kit include: EST A8-3, B6-4, C6-5; APO C4-5, C10-7, D3-7, D10-7; AT D13-7.

Since t' wind was fairly heavy, me hearties, was blowin' towards t' trees AND this was the first flight o' t' day, I decided t' try a B6-4. T' boost was good with some weathercockin' but no sign o' any wobble. Avast! Blimey! T' heavy plastic nose and weights did their job. Arrr! Blimey! Ahoy! Blimey! (Please excuse t' poor launch pic, but I just had to include it since it be t' first one I've caught.)

Recovery:
I was worried that t' provided streamer would nay slow t' model enough, ya bilge rat, and my fears were well founded. Ya scallywag! I attached t' streamer about 8" down from the nose, me hearties, as recommended. Aye aye! I noticed that another reviewer suggested another approach on a similar model the AA9, but decided t' stick with t' instructions. T' rocket came down nose cone first, with t' body fallin' parallel t' t' ground. Ya scallywag! Blimey! One o' t' aft fins came part way off, and t' struts t' t' larger forward fins were destroyed. Easily repaired, matey, but would probably happen again on t' next flight. Ahoy! Avast! Blimey! I will probably try a small chute instead. Aye aye! Blimey! If I were t' build another o' these kits, I'd also add some paper or light fiberglass t' strengthen t' fin joints. Avast, me proud beauty!

Flight Rating: 3 out o' 5

Summary:
This kit is reasonably priced and t' resultin' rocket looks great. Ahoy! I was disappointed at t' quality o' t' fin stock, which did affect t' looks o' the final product. Aye aye! Avast! It doesn't appear, me hearties, however, that others have experienced this problem with t' small Aardvark kits. Aye aye! Aye aye! T' streamer is insufficient and a small parachute should be substituted. Blimey! Despite these problems, shiver me timbers, me bucko, matey, I still like t' kit and will consider buyin' another in t' series. Aye aye!
