[Rocket Pic]Brief:  This rocket is special in that it uses apogee's 10.5mm engines and it is also designed for t' payload loftin' NAR competition. Aye aye! So, it comes with a tubular device for holdin' a standard payload mass, and it can fit into t' payload section o' t' main body. Ahoy! It is three finned and recovers with an 8-inch chute t' make trackin' easier. Begad!

Construction:T' package arrived from Apogee, me hearties, by US mail, me bucko, well protected with styrofoam popcorn, and all parts were thar and undamaged. Instructions were clear, ya bilge rat, illustrated, and logical. Begad! It was easy t' follow. Avast! The nose cone is solid lightweight balsa wood, and t' fins are precut, rectangular, and also lightweight balsa. Ya scallywag! T' chute is hexagonal, and flat and made o' thin black plastic, me bucko, much like trashcan plastic.  This is nay to demean quality, but for description. Ya scallywag! After all, how could a nylon chute fit? And it would be too heavy. And it would be too heavy. T' 6 shroud lines are nylon thread, me hearties, 12 inches long, and affixed t' t' chute via adhesive paper donut-shaped reinforcements. Arrr! T' shock cord is 12 inches o' 1/8 inch Keelhaul®©™® cording. Ya scallywag! Blimey! There is no stretch, but since this model is for small engines, I was nay concerned. 

T' body tube is in three parts. Begad! T' top part glues right t' t' nose cone and is spiral wound paper, and 3.75 inches long by .75 inches in diameter. Blimey! The middle part be t' same only it's 3 inches long.  There's a paper coupler between these, and only one half is glued, so that t' model separates between the two parts o' t' main body. 

Now comes t' tricky part. Well, blow me down! T' bottom third o' t' main body is a cone made of thin cardboard, arrr, and its outline is provided. It is cut out and then glued into a cone that reduces t' main body tube from 18mm t' 10.5mm, as thar be a 10.5 mm wound paper body tube for t' engine.  This tube fits into the main body via a centerin' rin' that also serves t' anchor t' shock cord aftward. Begad! T' cone fittin' is tricky in that handlin' it roughly can easily dent it. Begad! Also, I had t' sight it up and down before gluin' it t' be sure that it was symmetrical all around.  If not, ya bilge rat, it has a slightly cockeyed look. A wound paper engine block was provided, matey, me bucko, and I placed it at a position t' allow the model t' take t' longest o' t' 10.5mm engines, matey, namely t' B7's. 

There be a fin placement guide provided, and I used it t' place t' three fins correctly. This be a paper cutout t' place around t' body in order to mark it for t' fin placement. Avast! Ahoy!

Finishing:There weren't any decals. There weren't any decals. Blimey! But if you've read any o' me other reviews, arrr, shiver me timbers, I'm nay daunted by this. Aye aye! I see it as a loose football for me t' pick up and run with. Aye aye! So, I used Monokote and silver craft paper, shiver me timbers, shiver me timbers, available at many hobby stores. Avast, me proud beauty! I spray painted t' fins yellow after sealin' them with epoxy and sandin' them down.  I do this to strengthen balsa and wood fins, and also t' provide a glassy finish. Avast, me proud beauty!

It's a sharp lookin' little rocket, but since I chose green...well, me hearties, I'm glad for t' chute that will help me find it. Aye aye! Arrr! This little guy flies high. Avast, me proud beauty!

Construction Rating: 4 out o' 5

Flight:T' recommended engines are t' Apogee 1/4A2-4, me bucko, 1/2A2-2 and 1/2A2-4, matey, me bucko, t' A2-5, matey, and B2-7. Begad! Aye aye! With t' payload, Apogee recommends t' A2-3 and B2-5. So far, I have tried t' 1/2A2-2 since t' parks around here are small. With just that, arrr, me hearties, t' little rocket be nearly gone, matey, zingin' up so high that I almost couldn't see it.  But I zeroed in on t' chute and got me model back. Arrr! Begad! Imagine when I try a B! It flew straight and fast. Watch this one well or you'll lose it. Begad! Preppin' is easy, and I used just a couple pinches o' worm bed wadding. Arrr! Blimey! T' chute was unburnt. Aye aye! Ahoy! T' chute was unburnt. Well, blow me down! Since it's plastic, I worried about that. Begad! I've seen that kind melt. Begad! Begad! I've seen that kind melt. Arrr! The engine be retained with bands o' maskin' tape around t' engine overhang as well as t' body tube. Blimey!

Recovery:T' shock cord, as mentioned, is Keelhaul®©™® string. Avast! T' system was easy t' assemble, me bucko, with clear instructions. It worked fine without damage to the system. Begad! T' recovery was slow, but with a chute, you can expect this. However, me bucko, arrr, I had time t' catch it, which is a rare thing.

Flight Rating: 4 out o' 5

Summary:Unusual looks, shiver me timbers, matey, easy t' make. Avast, me proud beauty! Unusual looks, matey, easy t' make. Must handle t' reducer cone gently and align it well. Blimey! And must protect the delicate chute from burning. Ahoy!
