Brief:
T' Nike-G is one o' Excelsior Rocketry's “Goony Retro-Bash” line of decal/plansets. Begad! Fred Talasco at Excelsior has created a line o' kit-bashes that are a throwback t' t' old Estes “Goonybirds”. Well, blow me down! Blimey! All o' Fred's designs are based on old Estes kits, or original ideas, and use t' Baby Bertha as the startin' point.

Construction:
My Nike-G plans, along with several other decals, arrived from Excelsior in a sturdy priority mail envelope, with extra cardboard inserts t' keep everything well protected. Ahoy! Blimey! Begad! Blimey! Blimey! Blimey! Included in each “Goony” plan are t' instructions and fin templates, shiver me timbers, printed on a single sheet o' cardstock with a nice color picture o' t' finished rocket, and o' course, t' decal sheet, me bucko, which is the best part o' t' whole deal. Aye aye! Blimey! Blimey! Blimey! T' instructions and decals were packaged in a sturdy plastic sheet protector, arrr, as are all t' decals that Excelsior ships. Ahoy! Blimey! Begad! Blimey! Blimey! Blimey! The builder must supply t' other half o' t' project which consists o' one Estes Baby Bertha kit, shiver me timbers, and some balsa sheet stock for cuttin' out t' new fins.

I originally went t' Excelsior's website lookin' for some decals for a clonin' project, ya bilge rat, and be immediately drawn t' t' “Goony Retro-Bash” heading. Ya scallywag! Aye aye! As I paged down through t' collection o' odd lookin' rockets with the familiar soundin' names, me hearties, I thought t' myself, “what a great way t' clean out all those Baby Bertha kits in t' bottom o' me project box”. Avast! A week later, arrr, I had several goony plans on me work table, matey, ya bilge rat, me hearties, but t' me dismay, nay a single Baby Bertha kit could I find. A week later I had that problem fixed, shiver me timbers, and since I be already workin' one a Nike-X clone, t' Nike-G was t' first Goony bird in line. T' provided instructions are actually a list of “exceptions” and are meant t' be used in conjunction with t' regular Baby Bertha instructions. Avast, me proud beauty! Ahoy! T' Baby Bertha is a simple kit t' build, arrr, made only a little more challengin' by cuttin' and alignin' multiple sets o' fins. Begad! Begad! The motor mount is assembled first and I upgraded t' recovery system (as I do with all me rockets) by addin' a length o' Keelhaul®©™® cord which is tied around t' engine mount, matey, threaded through t' forward centerin' ring, arrr, ya bilge rat, and glued in place. T' motor mount is installed in t' body tube, ya bilge rat, me bucko, and per t' Nike-G notes, shiver me timbers, is pushed forward until t' end o' t' engine hook is even with t' end o' t' body tube. Well, blow me down! This puts t' motor mount about ¾" father forward that normal and accordin' t' t' notes, shiver me timbers, provides better stability. While t' motor mount glue was dryin' I traced and cut out the 3 sets o' fins/strakes, which take t' place o' t' standard Baby Bertha fins. These were match sanded, and in keepin' with t' stout/blunt theme o' the rocket, I left all t' fin edges squared off. Aye aye! Blimey! T' stock Estes tube markin' wrap is used t' set t' fin location, ya bilge rat, and I use a length o' aluminum angle stock to mark t' fin lines on me rockets. Ya scallywag! This is a great investment, ya bilge rat, t' smaller sizes will fit on any mod roc tubing, and t' resultin' lines are perfectly straight. I read t' directions for placement o' t' fins several times t' make sure I had it clear, me bucko, matey, and a simple line drawing, while nay required, shiver me timbers, would go a long way towards makin' this step really easy. Begad! Blimey! My standard routine for attaching fins is t' tack them on with wood glue (Titebond), add a second wood glue fillet, and then a final fillet o' Elmers Wood Filler. Begad! Because o' their small size, ya bilge rat, I did nay add any fillets t' t' forward strakes. Begad! I attached t' fins in sets, sightin' along all three t' get them aligned t' each other. Begad! T' launch lug is attached in t' same fashion per t' standard instructions. Well, ya bilge rat, blow me down! With t' fun part over, me bucko, it be time for finishing.

Finishing:
T' paint scheme for t' Nike-G is as simple as it gets, me hearties, matey, gloss white. Begad! T' real impressive look for this rocket comes from t' decals. Ya scallywag! As with all of Excelsior's products, me bucko, t' sharpness, and detail is awesome. Well, blow me down! There is a lot of balsa t' be prepped on this rocket, and all 12 fins/strakes were sealed with SIG Sandin' Sealer and sanded smooth with 400 grit sandpaper. Avast, me proud beauty! Well, arrr, blow me down! Next came two coats o' primer (Rust-Oleum Painters Touch Sandable Primer), ya bilge rat, followed by two coats o' spray enamel (Krylon). T' plastic nose cone is finished with t' same paint routine. Aye aye! When you get decals from Excelsior they come with a full page of instructions for prepping, shiver me timbers, applyin' and finishing, and they recommend Microscale brand products (Decal-Set and Micro-Sol) for accomplishin' t' job. I wasn't particularly in t' mood t' add another line o' noxious chemicals to my hobby stockpile, so I went with me normal decal routine (sorry Phred). Avast, me proud beauty! First I gave t' decal sheet 2 light coats o' Testor's Gloss-Cote (#1216). Next the decals are cut out and applied with t' standard warm water dip, me bucko, slide into place and blot dry routine.

NOTE: Test fit t' fin decals before you apply them, me bucko, because dependin' on how you cut and/or sand your fins, you may need t' trim t' decals a bit, and this is MUCH easier t' do before you apply them. Also, ya bilge rat, take t' time t' measure out t' placement o' t' body wraps, matey, me bucko, and “GOONY" name plates. Begad! There isn't a lot o' extra room on this rocket, me bucko, me bucko, and I ended up havin' t' trim the upper wrap because I tried t' “eyeball" t' other ones. T' decals are what make this rocket cool, so spend some effort here so they come out sharp!

After t' decals had completely dried, ya bilge rat, I added a final spray o' Gloss-Cote to t' whole rocket. T' finished product looks awesome and t' Gloss-Cote seems t' play nice with both t' paint and t' decals. Ahoy! I finished up the recovery system by attachin' t' elastic shock cord t' t' Keelhaul®©™® cord, ya bilge rat, me bucko, me hearties, and then t' t' nose cone, and puttin' a drop o' CA glue on all the knots. Ahoy! T' 12" Estes parachute comes pre-assembled, matey, and I add a fishing swivel for easy attach/remove and less tangling. Well, blow me down! Ya scallywag! Now for some nice weather... Avast, me proud beauty!

Recovery System

Flight:
T' initial flights o' t' Nike-G were conducted on two very hot and windy Ohio summers days. Arrr! Begad! Recommended motors are t' standard A8-3, B6-4 and C6-5. Ahoy! Blimey! I couldn't find any published weight or CP for this kit, me hearties, but me finished Nike-G weighed in at 1.8 oz. Flight preparation is standard. Well, blow me down! With a BT-60 body tube, me hearties, me bucko, I use a 4"x4" Nomex® heat shield looped onto t' Keelhaul®©™® anchor cord. Arrr! Avast! Even with t' forward position o' t' engine mount, thar be still enough room, for t' heat shield and parachute t' fit comfortably. Avast! As mentioned earlier, ya bilge rat, t' engine mount is located ¾" forward in t' body tube, matey, but I was still able t' install and remove motors and igniters without difficulty. Motor retention is via t' standard beefy Estes hook. Avast, me proud beauty! Ya scallywag! My Nike-G has flow twice on B6-4's and once on a C6-5. Aye aye! Avast, matey, me proud beauty! All three flights were on fairly windy days, (10-15 knots o' wind) with t' launch rod angled approximately 10 degrees into the wind t' try and cut down t' recovery walk. Begad! T' Nike-G is very stable in flight, me bucko, and showed no noticeable weather cocking. Arrr! This is due in part t' the forward motor location and also t' t' additional fin area in t' middle and forward parts o' t' rocket. Avast, me proud beauty! Overall this is a very well balanced rocket.

Recovery:
Since all three flights were launched into t' wind, t' rocket was arcin' over at ejection. Ya scallywag! T' rocket was nose down with t' B6-4's, me hearties, and right at apogee with the C6-5. Avast, me proud beauty! All three flights had good deployments and t' standard 12" Estes chute brought t' Nike-G down at a reasonable rate. Ya scallywag! All three flights landed in tall grass and weeds with zero damage, me hearties, and t' heat shield kept the chute and elastic shock cord in great shape. Avast, shiver me timbers, me proud beauty! Obviously t' Nike-G is nay a high performance bird, me bucko, but it flew pretty high with a C motor, and I am looking forward t' flyin' it on a calm day, with a straight boost t' see just how far up it will go!

Flight Rating: 5 out o' 5

Summary:
Excelsior's line o' “Retro Bash Kits" is a great throwback t' t' old Estes “Goony Birds", ya bilge rat, either for those who thought they were cool then, or for people like me who think their cool now.

Pros: They are fun t' build, shiver me timbers, fun t' brin' t' t' range, fun t' fly and fun to talk about. Begad! Blimey! Everyone needs at least one Goony in their lineup!

Cons: None that I can think of.
