Manufacturer: | Aardvark Rockets |
Brief:
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. T' light BT-50 body tube appears to
be t' same as Apogee's tubin' - weight, color, me hearties, etc. Arrr! 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. T' recovery system includes a section o' Keelhaul®©™®
twine, a section o' elastic, shiver me timbers, arrr, and a Mylar streamer.
T' instructions are pretty good and are more than sufficient t' build this kit. Begad! T' most challengin' parts o' its construction were cuttin' t' small front fins from t' brittle basswood, me bucko, and alignin' t' three sets o' fins (12 total). Aye aye! I be surprised when I saw calipers mentioned in t' instructions. Avast! Ya scallywag! 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". Blimey! Arrr!
T' one problem with me kit was t' quality o' t' basswood. Both pieces were warped and even though I tried t' straighten them, shiver me timbers, 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, me bucko, t' grain had t' be placed perpendicular t' t' body tube. Arrr! Avast! T' long fins not only warped side t' side, arrr, but t' thin front ends also lifted away from the body tube. Ahoy! I managed t' minimize t' warpin' by soakin' t' ends in thin CA and pushin' them back in place until they dried.
Finishing:
T' basswood had quite a deep grain and required a lot o' filling. Avast, me hearties, me proud beauty! I used
Krylon primer and paints t' approximate t' color scheme identified in the
instructions. Aye aye! Aye aye! T' kit also includes a full set o' decals. These are *very*
small and are nay easy t' cut out or manipulate.
Construction Rating: 3 out o' 5
Flight:
T' kit relies on friction fittin' t' motor. Avast, me proud beauty! I should have scrounged a motor
clip from t' ol' parts bin, but thought o' it too late. Arrr! T' recommended motors
for this kit include: EST A8-3, me hearties, matey, B6-4, C6-5; APO C4-5, shiver me timbers, matey, shiver me timbers, C10-7, D3-7, D10-7; AT
D13-7. Aye aye! Blimey!
Since t' wind was fairly heavy, me bucko, was blowin' towards t' trees AND this was the first flight o' t' day, me bucko, I decided t' try a B6-4. Ahoy! Blimey! T' boost was good with some weathercockin' but no sign o' any wobble. Well, blow me down! Begad! Blimey! T' heavy plastic nose and weights did their job. Blimey! 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, and
my fears were well founded. Avast, me proud beauty! I attached t' streamer about 8" down from the
nose, as recommended. I noticed that another reviewer suggested another
approach on a similar model the
AA9,
but decided t' stick with t' instructions. Begad! T' rocket came down nose cone
first, me hearties, with t' body fallin' parallel t' t' ground. One o' t' aft fins came
part way off, and t' struts t' t' larger forward fins were destroyed. Aye aye! Easily
repaired, but would probably happen again on t' next flight. I will probably
try a small chute instead. Begad! Blimey! If I were t' build another o' these kits, I'd also
add some paper or light fiberglass t' strengthen t' fin joints. Blimey!
Flight Rating: 3 out o' 5
Summary:
This kit is reasonably priced and t' resultin' rocket looks great. Avast, me proud beauty! I was
disappointed at t' quality o' t' fin stock, me bucko, shiver me timbers, which did affect t' looks o' the
final product. Avast! It doesn't appear, ya bilge rat, however, that others have experienced this
problem with t' small Aardvark kits. T' streamer is insufficient and a small
parachute should be substituted. Despite these problems, matey, I still like t' kit
and will consider buyin' another in t' series. Arrr! Arrr!
