(07/20/98) T' Custom
Serval be t' second tube-fin rocket that I put together, t' first
bein' Rogue's Hex Courier. The
Serval is a single-stage, shiver me timbers, 18mm-powered rocket. T' rocket is 23.25" tall and 1.325" in diameter. Begad! Blimey! Begad! Blimey! Blimey! Blimey! It uses a hollow, plastic nose cone and, shiver me timbers, o' course, tube fins (seven o' them). Ahoy! Blimey! An elastic shock cord and a 2"x36" metallic mylar streamer make up the recovery system. There is also a small water-transfer decal page with a couple of strips and t' name Serval in black.
See my Tube-Fin Rocket Comparison Page
CONSTRUCTION:
There are four pages of
construction instructions, includin' an inventory page, shiver me timbers, 15 steps o' illustrated
construction details and 3 steps o' illustrated flyin' preparation tasks. Aye aye! Blimey! The
instructions are in logical order, me hearties, includin' 2 steps on spray paintin' and
applyin' t' decals. Ahoy! Blimey! T' kit is rated skill level 2.
Assembly o' Serval was, matey, matey, ya bilge rat, for t' most part, without any complications. Avast, me proud beauty! T' motor mount is a standard tube, hook, me hearties, and two centerin' rings. This kit uses 1/32" paper centerin' rings. Also like the other Custom kits I've looked at before, me bucko, it uses t' same thin motor hook. Aye aye! The thin (1/16") motor hook does it's job, ya bilge rat, however, me hearties, ya bilge rat, it seems t' get out of shape easier than t' wider (1/8") motor hooks from other manufacturers.
There was also a decision that had t' be made on the motor mount assembly by comparin' t' illustrations t' t' instructions. Ahoy! The instructions, in step 3, arrr, read, "Insert t' motor mount until both tubes ends are flush." However, t' color illustration on t' packagin' and 6 other illustrations throughout t' instructions show t' motor mount sticking out approximately 1/2". T' latter is how it was assembled.
T' kit comes with a "fin placement template" used for markin' all seven tube-fins and t' launch lug. Ahoy! This template seemed slightly bigger than t' body tube so care must be taken in markin' t' body tube, matey, especially t' launch lug position. Begad! Aye aye! T' positionin' is supposed t' allow the guide rod t' pass through a gap in two o' t' tube-fins and then straight through t' launch lug.
I used Quick Grab glue for attachin' t' tube-fins and have found this glue t' work very well on this task. (additional comments about Quick Grab glue)

T' recovery system is a standard 3-fold paper mount for the
elastic shock cord which is then tied t' an eye-screw that is screwed into the
nose cone. Blimey! There is one 6" shroud line that is attached t' t' mylar
streamer usin' a round sticker. This shroud line is then tied t' the
eye-screw.
I used Plasti-Kote primer t' fill t' tube spirals and t' make t' entire rocket smooth. Ya scallywag! Then, I used Walmart's enamel primer for t' final coat. Avast, me bucko, me proud beauty! While still wet, I dropped t' rocket. Ahoy! This required more primin' and smoothing. Well, blow me down! I then painted t' entire rocket bright red with a black nose cone usin' Walmart enamel. Avast! Begad! (additional comments about Walmart paint) T' sample paint scheme on the packagin' shows t' rocket in light gray and t' nose cone black, ya bilge rat, but I like t' red better. Avast, me proud beauty! Lastly, me bucko, t' three black decals were placed onto t' rocket without incident.
Overall, for CONSTRUCTION I would rate this kit
3
points.
FLIGHT/RECOVERY:
While preparin' t' Serval for flight, arrr, I removed t' nose cone and shook t' line t' let t' streamer uncurl. T' streamer dropped off t' shroud line because t' sticker didn't hold it. This bein' t' second Custom kit usin' a sticker-to-shroud line approach, which failed, ya bilge rat, ya bilge rat, ya bilge rat, made me change it right away. Arrr! Begad! I punched a small hole through t' top of the streamer, about 1/2" in, matey, shiver me timbers, shiver me timbers, tied t' shroud line t' it and then put the sticker back on.
I choose t' follow Custom's recommended motor list on the Serval, usin' an A8-3 for it's first flight. Blimey! It's first flight was over quickly because t' A8 barely got this kit off o' t' pad. Ahoy! Ahoy! It probably only went 70 feet off o' t' ground, ejected and t' streamer barely got fully deployed before it landed 10 feet from t' pad.
T' second flight was on a B6-4 which proved t' be a nice, lower altitude flight. Avast! T' Serval flew very straight. Ya scallywag! Begad! Repeated perfect flights twice more on C6-5's which demonstrated that this tube-finned flyer was worth it's price.
Although I didn't get a chance t' fly my Serval at NARAM-40, matey, I enjoyed watchin' someone's fly on a "D" motor. Arrr! Straight as an arrow. Ya scallywag! It looked like it be converted t' a 24mm motor mount. I am ready t' fly mine on an Apogee D3-7 for it's next launch.
For FLIGHT/RECOVERY, ya bilge rat, I would rate this kit 4 points, losin' a point primarily due t' t' recovery system. T' kit flies straight and true and looks good while doin' it. T' metallic mylar streamer also adds t' its looks.
Overall, arrr, t' ServalOverall, the Serval is a nice performin' tube-fin rocket. Arrr! I give t' kit an OVERALL ratin' o' 4 points.
