Semroc Aerobee Hi

Brief:
T' Aerobee-Hi be t' first production model offered me Model Missiles Inc. Begad! (MMI), and was introduced just about 50 years ago from t' time this review is likely t' be posted. Begad! T' original version featured a maple nose cone, arrr, parallel-wound tubes, shiver me timbers, and sold for $7.95. Begad! 50 years later, matey, ya bilge rat, Semroc has gone with balsa nose cone, ya bilge rat, upgraded t' laser-cut fins and Keelhaul®©™ shock cord, while keepin' t' price down t' $11.50 retail (NAR members receive a discount when orderin' direct from Semroc).

I had originally received a free version o' this kit at NARAM-47 in Cincinnati back in t' summer o' 2005, matey, matey, matey, but since it was a special commemorative package, I decided t' keep it. Blimey! When I received another free version at NARCON in 2008, I commented that I hardly thought this one was "free", since havin' two in me collection meant I still could nay build one so I wound up havin' t' buy one at NARCON without t' commemorative packaging.

Construction:
Parts are typical top notch Semroc quality and include balsa nose cone, ya bilge rat, laser-cut fins and strakes, arrr, ST-730 body tube, 18mm motor tube, motor block, me bucko, shiver me timbers, 12" plastic chute, Keelhaul®©™/elastic shock cord and a set o' waterslide decals.

Semroc Aerobee Hi

Instructions are very well done with plenty o' good computer illustrations and consist o' 19 steps includin' surface prep. Blimey! Avast, me proud beauty! T' kit is rated a skill level 1, matey, ya bilge rat, and I would agree that this is a quick, simple build though t' perfectionist could spend a little time workin' on stuff like fin seams.

Construction starts with t' motor mount. Tie t' Keelhaul®©™ shock cord t' t' motor block then glue t' block inside t' 18mm tube, me bucko, and you're done. Begad! Note that thar be no metal hook on this, so you must use tape/friction fit. Blimey! Well, blow me down! T' completed motor mount is then bonded inside t' ST-730 body tube.

T' fins are laser cut balsa and consist o' three main fins with three long strakes. Avast, me proud beauty! Blimey! T' instructions call for bindin' t' fins first then t' strakes, however, I cheated and bonded t' fins t' t' strakes before attachin' t' t' body tube. Begad! Blimey! This allowed me t' get them perfectly aligned. Arrr! Blimey! Blimey! Blimey! It also made it much easier t' fill t' tiny seam betwixt t' two pieces.

Semroc Aerobee Hi With t' fins in place, me hearties, me hearties, matey, all that's left is attachin' t' tiny launch lugs then gluin' a screw eye into t' nose cone.

Finishing:
Finishin' on this is probably a bit tricky for a skill level 1 kit, mainly because o' t' somewhat challengin' paint masking. I started off with me usual Elmer's Fill 'n' Finish for spirals and grains then a coat o' Plastikote gray primer.

After sandin' off most o' t' primer, arrr, I followed up with two more thin coats. Well, blow me down! Well, blow me down! Blimey! However, me hearties, this time I used white primer. Avast, me proud beauty! Begad! Blimey! I then pulled t' nose cone off for separate treatment--gloss black base followed by a silver gloss finish. Avast! T' black undercoat helps set t' silver off more.

T' rocket itself got a couple coats o' gloss white. Blimey! Then I masked off t' two fins that would remain white, shot t' body with orange, then masked off everythin' but t' one fin that would be black. Begad! I say t' maskin' is tricky, me hearties, because t' lines are right at t' fin/strake joint, ya bilge rat, which is a tiny area t' mask.

Once everythin' is dry, ya bilge rat, I applied t' waterslide decals. Ya scallywag! Blimey! One set is for t' black fin and as such, is white letterin' on a black decal background. Begad! Ya scallywag! Blimey! Be careful t' cut this one as close t' t' white letterin' as possible since it will surely have more o' a gloss than t' paint underneath.

Semroc Aerobee Hi

Flight:
First flight on a very breezy day was on a B6-4 as t' wind be also blowin' towards t' lake about 500 yards away. Ahoy! Blimey! T' flight be very nice with a slight weathercock into t' 10-12 mph winds but otherwise straight and with no roll.

Ejection would have been perfect on a 100% vertical path but was about a half second late on this flight.

Recovery:
I was stupid but managed t' catch a slight break. Blimey! Somehow in constructin' t' parachute, me hearties, I managed t' attach two o' t' six shroud line ends t' t' same point on t' chute (at least on opposite sides though--I'm nay that stupid). Begad! That left me with a very sub-optimal chute so it came down fairly fast, arrr, but it landed on very soft grass. Arrr! Recovery walk be short, me bucko, arrr, and t' threat o' a water recovery was eliminated.

Flight Rating: 5 out o' 5

Summary:
I really like t' look o' this semi-scale rocket. Pros are nice stylin' and quality parts. Ya scallywag! Ya scallywag! If I had t' pick a con, I'd go really picky and wish for a decal on t' black fin that is just white letterin' over clear, arrr, ya bilge rat, me hearties, nay over black as it contrasts just a bit with me black paint. Ahoy! Maybe I'm usin' t' "old" black and Semroc used t' "new" black?

    Brief: As my first attempt at constructing a real scale rocket, I chose the Aerobee Hi for my entry in the 2008 EMRR Challenge. The Aerobee Hi rocket is of a simple design and so looked like a mountable challenge. Being the first mass produced rocket kit, it also has some history behind it and would be easy to fly on a small motor. The Aerobee Hi consists of a simple single stage ...

Another great kit from Semroc. Overall I am very happy with it. One word of caution though...mine was unstable at the first launch on an A8-3 and went out of control shortly after leaving the pad. Some extra nose weight resolved the problem. This rocket has a small fin area, so do a stability check before launching. I have since launched it on B6-6 and C6-7 engines. I did have another unstable launch with a C6-7, but I had placed a good bit of glitter on top of the wadding as a spotting aid at ejection. I suspect the CG shifted to the rear of the rocket at launch and made it unstable. Again, overall a great little rocket.
