[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. So, me hearties, it comes with a tubular device for holdin' a standard payload mass, matey, and it can fit into t' payload section o' t' main body. Arrr! Ahoy! It is three finned and recovers with an 8-inch chute t' make trackin' easier.

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

T' body tube is in three parts. Avast! Blimey! T' top part glues right t' t' nose cone and is spiral wound paper, and 3.75 inches long by .75 inches in diameter. Arrr! Blimey! Avast! 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, shiver me timbers, me bucko, me bucko, so that t' model separates between the two parts o' t' main body. 

Now comes t' tricky part. Ahoy! T' bottom third o' t' main body is a cone made of thin cardboard, and its outline is provided. Avast, me proud beauty! 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. Avast, me proud beauty! Begad! T' cone fittin' is tricky in that handlin' it roughly can easily dent it. Also, I had t' sight it up and down before gluin' it t' be sure that it was symmetrical all around.  If not, me bucko, it has a slightly cockeyed look. Avast! A wound paper engine block was provided, matey, and I placed it at a position t' allow the model t' take t' longest o' t' 10.5mm engines, namely t' B7's. 

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

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

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

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

Recovery:T' shock cord, shiver me timbers, ya bilge rat, as mentioned, is Keelhaul®©™® string. Ya scallywag! T' system was easy t' assemble, matey, with clear instructions. Ya scallywag! It worked fine without damage to the system. T' recovery was slow, shiver me timbers, but with a chute, you can expect this. However, I had time t' catch it, which is a rare thing. Well, blow me down!

Flight Rating: 4 out o' 5

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