Semroc Lune R-1

Brief:
Single stage 18mm payloader. Aye aye! Single 12" parachute recovery. 6" long payload section. Ahoy! Blimey!

Construction:
T' kit contains two sections o' body tube: one for t' booster and one for the payload section, shiver me timbers, ya bilge rat, four laser cut balsa fins, balsa nose cone, balsa tube coupler, me bucko, motor tube, two centerin' rings, thrust ring, motor retainin' hook, launch lug, matey, screw eye, ya bilge rat, me hearties, Keelhaul®©™® cord, elastic cord, 12" colorful plastic parachute, and decals. Ahoy! All materials were very high quality and some components, such as t' motor mount, parachute, Keelhaul®©™® and elastic cord, ya bilge rat, all come packed in sub-assemblies makin' them easier t' find and small parts harder t' lose. I ordered me kit directly from Semroc, shiver me timbers, and it arrived so well packed in packin' peanuts and air bubble packin' you could've dropped an anvil on it and it would've come through OK. Ahoy! Semroc obviously cares about their products and their customers.

Semroc's instruction booklets are superb. Well, blow me down! Ahoy! Blimey! I have built three o' their kits and each shows their obvious attention t' detail. Arrr! Avast! Blimey! There is a complete pack list with illustrations and labels for each part, makin' it easy t' be sure everythin' is there. Ya scallywag! A nice list o' needed tools is on t' first page. The instructions are broken down into logical sub-assemblies with check boxes next to each step so you know right where you left off. Aye aye! Ahoy! Blimey! Each step is well illustrated so thar be never any confusion. Avast, me proud beauty! Begad! Blimey! All t' parts fit like they are supposed to, arrr, construction be straightforward with only a basic hobby knife, glue o' choice, matey, ya bilge rat, ruler, and sandpaper, ya bilge rat, required for t' build. Arrr! Blimey!

Finishing:
There's nothin' special about finishing, matey, ya bilge rat, just follow t' directions. Well, blow me down! Filling and sandin' t' balsa takes a little time, ya bilge rat, but is well worth t' effort. Well, blow me down! I didn't fill t' spiral gaps in t' body tube, but you can hardly tell as they are so smooth anyway. Avast, me proud beauty! I didn't use t' decals, which is just a personal preference. Ahoy! They really didn't go with me color scheme either. I really like the long sleek look o' t' model with t' sharp point o' t' nose cone.

Construction Rating: 5 out o' 5

Flight:
I flew it once on each o' t' recommended motors. Begad! All were very good flights, although I had a little trouble with parachute deployment. Avast, me proud beauty! This was by no fault of t' kit, however, ya bilge rat, arrr, it just got wrapped too tight and tangled. Aye aye! I used about five sheets o' waddin' per flight, shiver me timbers, t' motor hook makes for quick and easy flight prep and turnaround times for t' next flight. Begad! It had a little wobble when launched on t' B motor for some reason, t' rest o' t' flights were real straight t' whole way. Well, blow me down! It didn't quite achieve t' altitudes I thought it might (just by eye-ballin' it, me bucko, arrr, thar was no trackin' or altimeter) but then again, I was launchin' with me brother who was flyin' a Quest Aerobee-Hi kit, so obviously he be gettin' much higher on t' same motors with his smaller, lighter kit. Begad! Overall though, matey, a very pleasin' performance.

Recovery:
T' Keelhaul®©™® cord is attached t' t' motor retainin' rin' and is longer than t' booster section. Well, blow me down! T' Keelhaul®©™® cord and t' elastic cord are then knotted together. I really like t' Keelhaul®©™®, since whenever t' elastic cords go t' far down they get burned through. Begad! When the chute did deploy on t' last flight, me hearties, it performed fine with an average rate of descent. On t' flights where t' parachute didn't deploy, matey, it came down sideways and be recovered with no damage. Looks like it will be a durable rocket that has a lot more flights in it.

Flight Rating: 4 out o' 5

Summary:
This is a great second rocket but ease o' construction would make it fine for a first time builder as well. Avast! T' payload section isn't huge, me bucko, but I usually don't fly anythin' in mine anyway. Arrr! It would still probably easily accommodate some of the smaller altimeters though, such as t' AA powered one available from Apogee Components. Ya scallywag! I haven't found much about t' rocket that I don't like yet.

Overall Rating: 4 out o' 5

  • Semroc Lune R-1 By Chan Stevens

    Brief: This kit was originally produced by Semroc in 1969 as competition to the Centuri Arcon and has been faithfully reproduced today. It's a simple 4-fin construction and with the payload bay, it could be a nice means of venturing out of the basic intro rocket kits. Construction: Ben's review covered the parts fairly well. I'll add that the body tubes are the original ...
