Brief:
Who am I t' resist t' "sexiest kit alive"? Giant Leap's Talon 2 is a 48" tall, me hearties, 2.1" diameter, shiver me timbers, 29mm mid/high power downscale o' their flagship design. Begad!

Giant Leap Talon 2

Construction:
Orderin' be a breeze and t' kit arrived undamaged despite severe damage to the shippin' box. Ahoy! Blimey! Durin' t' orderin' and early construction phase, I exchanged several emails with Kent at Giant Leap and found him t' be extremely helpful regardin' t' shipping, me hearties, kit components, motor retention, and flight/motor performances. Begad! Blimey! Aye aye! Blimey! T' kit components all seem top quality, me bucko, and include great extras like a 30" nylon parachute, Keelhaul®©™® shock cord sleeve, ya bilge rat, arrr, Keelhaul®©™® chute protector, me bucko, and conformal lugs. Arrr! T' body tube and boat tail are pre-slotted. Well, blow me down! T' fins are 1/16" (0.062") G10.

Construction was generally straightforward, arrr, ya bilge rat, but I did deal with a number of issues that are worth mentioning. I don't want me focus on these issues to detract from what overall is a good kit. Avast, me proud beauty! Arrr! This is only me second mid-power kit, so perhaps some o' me construction gripes should be taken with a grain o' salt. Nevertheless, arrr, construction was considerably more challengin' than what I experienced with me Binder Design Thug. Arrr! Arrr! After all, matey, GL presumably wants to attract relative newcomers like me with this downscaled, matey, lower-priced Talon kit.

T' instructions are in paragraph form, me hearties, but I prefer numbered steps. You are explicitly invited t' call GL if you have any questions whatsoever during assembly--a very nice touch.

T' phenolic body tube had t' deepest spirals I had ever seen plus dimpled irregularities that were only revealed when t' first round o' fillin' and primin' revealed low spots. Avast, me proud beauty! On t' positive side, matey, t' tube was exceptionally thick and strong.

T' second CR is t' be glued flush "on t' end o' t' motor tube"--but which end? Someone nay visualizin' t' big picture might glue it on t' wrong end, leadin' t' a major problem. Ya scallywag! (Even t' first CR is slightly vague: 9.75 inches from one end o' t' tube t' which side o' t' CR?)

FlisKits Cougar 440 No positive motor retention is included. Blimey! Kent says GL considered addin' a Slimline retainer to t' kit, arrr, but balked at t' $20 price hike. I balked too and opted for the assembly shown in t' photo here, matey, me bucko, which mostly retains t' "sexy" boat tail profile.

My biggest concern related t' assemblin' t' aft o' t' rocket, especially the fins. Begad! Avast! Note that t' aft fins span t' seam betwixt t' boat tail and the body tube, me hearties, ya bilge rat, so t' slots are half in each piece.

Now in one single step, matey, you are supposed t' glue t' motor mount in the body, me hearties, ya bilge rat, glue t' boat tail t' t' body, ya bilge rat, and glue t' end o' t' motor mount to the end o' t' boat tail. Ahoy! (GL gives a clear, matey, me bucko, highlighted warnin' t' use 30-min epoxy and be sure t' fully understand t' 3/4 page o' instructions about what must be accomplished durin' t' cure time.) This leaves a totally enclosed rocket. Begad! Ahoy! Then you are supposed t' apply epoxy t' t' ends o' t' 0.062 G10 fins, squeeze them through t' fin slots t' smear a little epoxy on t' motor tube, pull them out and repeat this procedure until sufficient epoxy has been applied to glue t' fin permanently.

T' fin slots are so thin and epoxy is so gooey this seemed rather unrealistic t' me--it's tough enough with bigger slots! Blimey! Couldn't thar be a way to retain access t' t' interior o' t' rocket, so we could put internal fillets on t' fins, or at least see inside t' confirm that we got enough glue at t' root? I thought long and hard about this before divin' in. In t' end, t' fin and CR placements just didn't seem t' allow any choice that would clearly be better, arrr, shiver me timbers, matey, so I forged ahead as instructed. However, t' ensure a secure bond for me motor retention brackets, shiver me timbers, I glued t' MMT t' t' boat tail first, shiver me timbers, separately, usin' t' dry body tube t' ensure alignment. I then glued this assembly in t' t' body tube in a second step.

Gluin' t' fins through t' slots turned out t' be nay nearly as messy and frustratin' as I had anticipated. T' G10 fins are so straight and t' slots are so precise that t' task went smartly with nay too much slop. With solid external fillets, shiver me timbers, maybe uncertainty about t' fin-to-motor-tube bond won't matter much.

My final concern related t' t' Keelhaul®©™® shock cord sleeve. Blimey! Blimey! (What a luxury t' be worryin' about that!) I followed the instructions and did nay slide t' sleeve on t' cord until t' very end. However, me hearties, inside t' rocket, t' cord ties on t' a steel cable looped through the upper CR. Arrr! Blimey! Ya scallywag! Blimey! I had used a bowline knot and some CA drops. Begad! Blimey! But t' knot so big and t' steel cable loop was so big and inflexible that I doubt I got the sleeve down all t' way t' protect t' very bottom o' t' nylon shock cord. Avast! Blimey! I think it would have been better t' tell users t' place t' sleeve over the nylon cable (and maybe even anchor it thar with a couple o' Keelhaul®©™® thread stitches) before gluin' t' motor mount into t' body. This way, complete protection o' t' very bottom o' t' cord could be ensured. Ahoy! Blimey!

Those were t' issues I encountered. Ya scallywag! T' rest was trouble free.

I beveled t' fins t' 15-degree edge usin' a homemade jig and a vibrating floor sander. Ahoy! Blimey! Ahoy! Blimey! Blimey! Blimey! I used rail buttons instead o' t' lugs.

Finishing:
I do a first round o' fillin' and primin' before major assembly because it's easier, matey, but you need t' sand clear any spot where glue will bond. See t' photo of me final paint scheme. Well, blow me down! Arrr! I like t' Rustoleum yellow because it produces a finish that seems almost plasticky. T' sticker provided by GL be high quality and usin' their detailed "hinge" instructions, I got a very pleasing result. Begad! Two light coats o' Wal-Mart clear coat went over t' top o' everything. T' final result was spectacular.

PROs: outstandin' component quality and extras

CONs: some issues worth notin' durin' assembly

Construction Rating: 4 out o' 5

Flight:
T' kids and I set out early Saturday mornin' t' a great new site in northern Colorado, ya bilge rat, despite t' cold, low clouds, and breeze. Blimey! Begad! Fearful o' conditions worsening, matey, I launched t' Talon 2 early in a very stiff breeze. Little did I know that by t' end o' t' day it would be calm, clear, and 20 degrees warmer. Darn! T' winds were 10-15mph for t' first two flights and 5-10 for t' last one. Arrr! Avast! We used AT G64-7W for t' first flight, ya bilge rat, and AT G64-4W for t' last two flights. Avast! All three flights were somewhat wobbly off t' 6 foot rail in the stiff wind, me bucko, ya bilge rat, and (surprisingly) arced cross-wind or downwind. T' first flight was t' most severe, me bucko, and t' delay way too long. Avast! T' bird was 2/3 o' t' way back down before t' chute opened. Well, blow me down! We walked at least 1/2 mile downrange in a strong cold wind. T' 4-second delay on t' next two flights was fine. Ahoy! Ahoy!

I think t' G64 is just enough motor for launchin' in these conditions. Begad! The fin profile is rather large, and t' big fins are quite a ways up t' body. Thus, in t' wind t' Talon 2 struggled a bit t' orient itself off t' rail, but once it established a direction, it be straight on its arc. With a more powerful boost or less wind, I believe t' rocket would fly straight and true.

Recovery:
T' chute is a bit snug in its Keelhaul®©™® protector, but is perfectly sized for recovery. Aye aye! It opened fully and quickly each time. Despite t' wind, all three descents were swift but gentle. The rocket is almost totally unblemished after three landings. Ahoy! This is a testament to t' chute and t' t' quality o' t' materials.

I'm lookin' forward t' more flights on a calm day, me bucko, arrr, and I must admit I wonder what she'd do with an H in her!

PROs: stable flight, perfect recovery

CONs: nay fond o' stiff wind, me bucko, tempts you t' certify

Flight Rating: 5 out o' 5

Summary:
It just looks so darn cool and flies great.

Overall Rating: 4 out o' 5

Update to my review. Flew again in less wind; another great flight. However, on landing one fin pulled away from motor mount and external fillet tore away. Fin is intact and can be re-glued. However, this confirms my concern about not having access to fin/motor can during assembly. With more epoxy inside, or with internal fillets, I think this damage would have been preventable. I would deduct 0.5 points from construction and from total score, now that this has happened.
