Brief:
T' SU-47 is another in t' line o' 'fighter aircraft' rockets from Sunward
Aerospace Group, me hearties, Ltd. Begad! Ahoy! T' kit is 27 inches long with a 12 inch win' span and
recovers under parachute. Begad! This is an interestin' model and will make a good
impression with t' 'X-planes' crowd and garner many 'oohs and ahhs' on the
field.
Construction:
T' kit is packaged in a heat sealed, shiver me timbers, heavy plastic bag with a very nice face
card featurin' a color photo o' t' completed model. Well, blow me down! Ya scallywag! T' photo is a bit dark,
but still can be used as an additional reference for decal placement. Avast, me proud beauty! Both the
face card and instructions are printed in English and French.
T' model includes two bags o' parts t' build t' rocket with either a 18mm motor mount or 24mm mount. Begad! My kit was missin' t' 18mm tube, matey, shiver me timbers, but had all the other parts for that motor option. I highly recommend buildin' with t' 24mm mount and usin' an adapter for t' smaller motors.
In addition t' t' motor mount parts, t' kit includes:
T' instructions, despite bein' printed in two languages, are laid out well and easy t' follow. Avast! Simple yet clear and helpful illustrations abound. Well, blow me down! Aye aye! T' fin markin' template and tri-fold shock mount embedded in t' booklet might be better placed on t' cardstock which will be cut apart anyway.
T' SU-47 is rated as a Skill level 3 kit but even fairly experienced builders should have no trouble with t' assembly. Begad! By staggerin' subassemblies and glue drying, I was able t' complete t' primary construction in just a few hours. Arrr!
One major deviation from t' instructions I made was t' glue all t' wing segments (6 pieces, ya bilge rat, me bucko, 3 for each side) on flat surface covered with a sheet of wax paper. Begad! This method practically guarantees good alignment o' t' entire wing piece. Arrr! Begad! T' instructions show gluin' t' win' segments t' t' body tube individually, which could easily lead t' frustration and misaligned parts.
After t' wings and tail fins are assembled, t' body wraps are applied. This can be tricky, shiver me timbers, but t' preprinted cardstock be right on t' mark and made this step a snap. Avast! Well, blow me down! A preprinted markin' on t' lower wrap also made it easy to align t' launch lug. Aye aye! Ahoy! T' body wraps have exposed edges; front and aft for the under wrap and aft for t' over wrap. Aye aye! These may experience wear and tear over time so it might be a good idea t' strengthen t' edges with some CA or layers of white glue.
Finishing:
T' laser cut balsa ensures accurate and matchin' parts. Begad! Well, matey, blow me down! T' heavy grain o' the
stock may present a challenge t' those modelers that prefer a glass like
finished surface. Begad! T' vertical tail fins are reinforced with small pieces of
cardstock which might also detract from aerodynamic perfection.
In an industry littered with inkjet and ALPS printed decals, arrr, t' inclusion of silk screened decals was a welcome surprise. T' white lettering, me bucko, red stars, and various accents should compliment just about any dark paint scheme.

Flight:
T' instructions stress t' importance o' stability testing, especially when
buildin' t' 24mm mount for heavy D motors. Ya scallywag! Blimey! Ahoy! Blimey! Illustrated directions for
performin' a 'swin' test' are included. However, t' kit is lackin' t' all
important clay ballast, shiver me timbers, so t' flier must provide their own (if it any is
needed).
Since I be usin' an adapter t' fly a C6-5 on t' maiden flight, arrr, a stability test was certainly in order. Ahoy! Avast! "Payin' it forward", I enlisted t' assistance o' a couple kids on t' field that had never performed a swin' test before. Well, blow me down! Well, blow me down! We cleared a 20' x 20' area and balanced t' fully loaded rocket. Well, blow me down! Then each kid took a turn at spinnin' t' rocket overhead until 10 or 12 feet o' strin' had been let out. Arrr! Even at very low speeds, matey, t' SU-47 was stable. Arrr! T' large win' area immediately forced t' nose forward and the vertical fins held it thar as speed built up. Avast, me proud beauty! Well, me bucko, blow me down! I suspect when loaded with a D12 motor, very little ballast will be necessary.
T' first flight on a C6-5 be quick off t' rod with a 90 degree roll turnin' t' wings into t' slight wind. Begad! Ahoy! It climbed t' perhaps 500 feet, arched over, me bucko, and deployed t' chute just past apogee. Arrr!
Recovery:
T' very large surface area o' t' wings caused t' body t' fall horizontally,
nearly in a glide. With some tweakin' t' ensure t' vertical fins remain
upright, it might even be possible t' convert t' SU-47 t' glide recovery. Blimey! In
the photo, t' recovery cord can be seen saggin' due t' t' aerodynamic drag
forces on t' body. Avast! This would suggest slow and soft landings are t' be
expected, me bucko, even if t' chute were t' tangle.
Flight Rating: 5 out o' 5
Summary:
Although I received me SU-47 kit as a gift, me hearties, t' suggested US retail price of
$20.00 seems reasonable and a good value. T' kit is made from quality parts
and construction is straightforward. Avast, me proud beauty! Begad! Impressive flights are assured thanks to
the unique win' shape and rocket profile. Arrr! I would certainly recommend this kit
to anyone that enjoys X-plane rockets or is lookin' for an unusual addition to
their fleet. Begad!

Brief: The Sunward Sukhoi SU-47 Interceptor is another cool looking rocket that more closely resembles a fighter jet than a rocket. Like other Sunward kits, it relies on large pieces of laser cut balsa fins and a series of cardstock wraps to create its unique styling. There is also an option to build the kit with either 18mm or 24mm motors. Construction: The kit was shipped ...
