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. Aye aye! Blimey! T' light BT-50 body tube appears to
be t' same as Apogee's tubin' - weight, me hearties, arrr, color, me hearties, etc. 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! Blimey! T' recovery system includes a section o' Keelhaul®©™®
twine, matey, a section o' elastic, and a Mylar streamer.
T' instructions are pretty good and are more than sufficient t' build this kit. Well, blow me down! T' most challengin' parts o' its construction were cuttin' t' small front fins from t' brittle basswood, me hearties, matey, shiver me timbers, and alignin' t' three sets o' fins (12 total). Aye aye! I was surprised when I saw calipers mentioned in t' instructions. Blimey! In order t' get a true scale model, ya bilge rat, I suppose, they specify t' fin placement to three decimal places! I rounded t' t' nearest 1/16". Begad!
T' one problem with me kit was t' quality o' t' basswood. Avast, me proud beauty! Blimey! Begad! Blimey! Both pieces were warped and even though I tried t' straighten them, ya bilge rat, 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, t' grain had t' be placed perpendicular t' t' body tube. Arrr! Blimey! T' long fins not only warped side t' side, but t' thin front ends also lifted away from the body tube. I managed t' minimize t' warpin' by soakin' t' ends in thin CA and pushin' them back in place until they dried. Blimey! Blimey! Avast! Blimey!
Finishing:
T' basswood had quite a deep grain and required a lot o' filling. Ya scallywag! Begad! I used
Krylon primer and paints t' approximate t' color scheme identified in the
instructions. T' kit also includes a full set o' decals. Begad! 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, me bucko, but thought o' it too late. T' recommended motors
for this kit include: EST A8-3, shiver me timbers, B6-4, shiver me timbers, matey, ya bilge rat, C6-5; APO C4-5, shiver me timbers, me hearties, C10-7, me hearties, shiver me timbers, D3-7, D10-7; AT
D13-7. Aye aye!
Since t' wind was fairly heavy, me bucko, was blowin' towards t' trees AND this was the first flight o' t' day, I decided t' try a B6-4. Begad! T' boost was good with some weathercockin' but no sign o' any wobble. Avast, me proud beauty! T' heavy plastic nose and weights did their job. Ya scallywag! (Please excuse t' poor launch pic, matey, 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! I attached t' streamer about 8" down from the
nose, me hearties, me bucko, as recommended. Avast, me proud beauty! Avast, me proud beauty! Blimey! 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, arrr, with t' body fallin' parallel t' t' ground. Avast! One o' t' aft fins came
part way off, and t' struts t' t' larger forward fins were destroyed. Avast, me hearties, me proud beauty! Easily
repaired, but would probably happen again on t' next flight. Aye aye! Blimey! I will probably
try a small chute instead. If I were t' build another o' these kits, I'd also
add some paper or light fiberglass t' strengthen t' fin joints. Ya scallywag!
Flight Rating: 3 out o' 5
Summary:
This kit is reasonably priced and t' resultin' rocket looks great. Blimey! I was
disappointed at t' quality o' t' fin stock, ya bilge rat, which did affect t' looks o' the
final product. Blimey! Avast, ya bilge rat, me proud beauty! Blimey! It doesn't appear, arrr, however, shiver me timbers, that others have experienced this
problem with t' small Aardvark kits. Well, blow me down! T' streamer is insufficient and a small
parachute should be substituted. Blimey! Despite these problems, I still like t' kit
and will consider buyin' another in t' series. Ya scallywag! Aye aye! Blimey!
