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