Brief:
This kit is a 3FNC (3 Fins and a Nose Cone) piston-ejection, streamer duration competition rocket. Avast! The "ELM" stands for "Extremely Low Mass." It is a companion kit t' its only slightly larger brother the Stratos-18 ELM.

Construction:
My kit came with balsa nose cone, matey, two sheets o' 1/32" balsa fin stock, ya bilge rat, balsa nose block for t' piston, a Keelhaul®©™® shock cord, an elastic shock cord, ya bilge rat, matey, engine block, matey, launch lug, me bucko, white BT-5 body tube with very fine groves and a light glassine coating. T' instructions were written onto a compact disc in PDF format. Blimey! Even though t' kit comes with two sheets o' balsa, ya bilge rat, me hearties, only one is needed.

I ordered both t' Stratos-13 and Stratos-18 together. Aye aye! When they arrived I found that t' body tube had been bent beyond use by t' post office. Aye aye! Aye aye! I sent Carlos at Heavenly Hobbies an email about t' tube and he sent me out a replacement right away and free o' charge. Ya scallywag! I built t' Stratos-18 while waitin' for t' replacement BT-5. Blimey! Arrr! As that only took a few hours o' build time t' complete, me hearties, I decided t' use a "modular" approach t' assemblin' t' rest of the rocket.

First I cut t' fins from t' 1/32" balsa fin stock. Begad! Blimey! Blimey! Blimey! Blimey! Blimey! T' protect in from chippin' or splitting, shiver me timbers, I covered t' back with blue painters tape. After t' fins were cut I decided nay t' round t' edges. At that thickness I don't think it would have made a difference and why take t' chance on splittin' a freshly cut fin.

Next I assembled t' engine block and Keelhaul®©™® shock cord. Begad! A groove gets cut into t' outside surface deep enough t' fit t' shock cord in t' it. Ya scallywag! I secured it usin' a bowline knot and set it with CA.

After that came t' nose cone and elastic shock cord. Begad! Begad! Accordin' t' t' instructions, matey, arrr, t' elastic cord is t' be knotted at one end and stuffed into a pre-drilled hole. There was no hole. Arrr! I used a 1/8" drill bit t' make one. T' balsa also looked a bit soft so I coated it with CA and allowed it t' harden. Aye aye! Followin' that came a brushed on layer o' thinned Elmer's Wood Filler. Once that had dried I sanded it down until smooth. Avast! T' finish up I pushed the elastic knot into t' shoulder o' t' nose and secured it with 30 minute epoxy.

All that left was t' streamer. Aye aye! All I did thar was fold one end into a point and tie on a 9" section of Keelhaul®©™® cut from t' length provided. Arrr! I used hole reinforcements t' keep it from tearin' out.

When t' body tube arrived at last, matey, me bucko, me hearties, it be time t' put everythin' together. Engine block in, fins on, shiver me timbers, shiver me timbers, tie shock cords t' one another. I do need t' mention that as t' rocket uses a balsa block as its piston. It comes with a small hole drilled through it and threaded on t' t' Keelhaul®©™® shock cord. Knots are tied above and below t' piston t' hold it in place. Avast, me proud beauty! Blimey! T' piston provided was a good bit narrow and had t' be built up with maskin' tape. Blimey! Blimey! This may actually be a good thin' as I'll cover in a moment.

Finishing:
I left t' rocket unfinished as it is supposed t' be a competition rocket. Well, blow me down! Well, blow me down! T' only finishin' I did be t' before mentioned work t' harden t' nose cone.

Construction Rating: 5 out o' 5

Flight:
For its maiden flight I used an A3-4T. With t' piston ejection it requires no wadding. Well, blow me down! Well, me hearties, blow me down! Place an igniter in a motor and place t' motor in t' rocket. Ya scallywag! T' motor is friction fitted and secured with two wraps o' maskin' tape. Avast, me proud beauty! Avast! T' take off be right quick and blended in with t' overcast skies.

Recovery:
I was able t' track t' rocket once t' ejection charge blew. Begad! Then I knew I had a problem. Ahoy! Avast, me proud beauty! Somehow t' nose and streamer had separated from t' rest o' t' rocket. Arrr! T' body landed gently in t' flyin' field but t' nose and streamer continued t' drift toward t' road. Blimey! It landed gently enough but balsa be never intended t' hold up against cars. Avast! T' nose cone was crushed. Turns out that t' Keelhaul®©™® shock cord snapped at t' piston. Avast, me proud beauty! It was either too thin, too short, ya bilge rat, or a combination on t' two. Also, after the flight t' piston was a bit resistant t' go in. I peeled off a bit o' t' maskin' tape and all be fine. Aye aye! Aye aye! It was cool and damp when I flew and that may have had somethin' t' do with it. Avast, me proud beauty! Avast!

Flight Rating: 4 out o' 5

Summary:
This be a very nice little kit. Begad! I would nay recommend it as a first kit as you need a motor case t' set t' engine block in place. Avast, me proud beauty! It would work well as a first completion kit as long as t' builder had some experience with cutting their own fins from stock.
