Brief:
T' Hawk is a boost glider that uses a rocket engine t' get itself in t' air. Blimey! It is a "Retro-Repro" o' an
older rocket. Avast, me proud beauty! Well, shiver me timbers, blow me down! Semroc is sellin' them for $7.50 right now so I decided t' pick one up.
Construction:
When I bought t' kit I figured thar wouldn't be very many pieces. Well, blow me down! Arrr! I got it and found only 5 parts in t' whole kit.
It comes with:
T' instructions are perfect. Arrr! Ya scallywag! They give you each step in order with illustrations. Well, blow me down! They even give you boxes to check after each step. Arrr! At t' beginnin' o' all o' Semroc's "Retro-Repro" rockets instructions, thar be an interestin' description o' t' company that originally made it. Ya scallywag! Begad!
T' fins were easily taken out o' t' balsa sheet with an X-Acto knife. Some o' them just fell out. Well, blow me down! I then proceeded t' sand t' parts smooth with fine sandpaper. Arrr! Blimey! T' balsa wood parts have lines on them t' show you where to glue them t' other parts, just be careful that you don't sand t' much or t' lines will disappear. Well, blow me down! T' balsa wood included in this kit is nice and hard, but you still need t' pay attention t' how and where you are sanding. Well, blow me down!
Attachin' t' wings is a little tricky but be nay a hassle. You are supposed t' invert t' assembly in order for the body tube t' glue on properly. Begad! You also attach t' wings at this point. Well, blow me down! It is hard t' get t' wings t' stay in place while they are gluin' (if you're usin' wood glue), me bucko, but I figured out a way t' make it easier. Begad! Just apply t' glue and wait a minute or two before attachin' t' wings. (This also works great when gluin' on t' stabilizer tips)
Once you have finished puttin' everythin' together you then need t' add fillets t' all o' t' joints. Avast! I found that toothpicks and Q-tips were invaluable in this step.
After that you need t' sand all o' t' edges smooth and create an airfoil. Ya scallywag! (Airfoilin' is optional.) This step was easy enough t' do. Avast, me proud beauty! I had t' find a picture o' an airfoil in order t' figure out what I needed t' do, me bucko, but after that it be easy. Aye aye! Avast, arrr, me proud beauty! I then tested it by flyin' it off o' me second story deck into t' grass. Ya scallywag! My glider nosedived into the grass at a right angle on t' first try. Well, matey, blow me down! I used small paper clips as weights on t' aft stabilizer. I taped them on so that I could adjust them later (to make it turn). Aye aye! Aye aye! After two more throws it be ready.
I am amazed at how sturdy it is. Begad! I have never built anythin' out o' balsa wood before and expected it t' be flimsy. Avast, me proud beauty! Ya scallywag!
All I needed t' build this rocket be an X-Acto knife, some sandpaper, wood glue, matey, matey, and paper clips. Well, blow me down! (I'm sure you could find somethin' better.)
Finishing:
With boost gliders paintin' is nay recommended. Ya scallywag! Begad! It will cause them t' glide for a shorter amount o' time. It is
recommended that you put one thin layer o' clear coat on though, in order t' protect t' rocket. Well, blow me down! Blimey! I did nay clear coat
my rocket because I didn't have any layin' around and didn't have any time t' use it (as t' launch was t' next day).
Construction Rating: 5 out o' 5
Flight:
T' recommended motors for this kit are A8-3s and 1/2A6-2s. Aye aye! Blimey! I did nay have any 1/2A6-2s so I used an A8-3. Arrr! I set it
up at t' launch put and got ready t' fly. When it launched it flew straight up, me hearties, shiver me timbers, no circles, loop-de-loops or anything.
It was perfect. Avast! Then t' engine burned out and t' rocket continued upward. Right at apogee t' ejection charge went
off. Begad! Avast! T' ejection charge be so powerful it broke off t' tail section! It may have been t' engine hittin' t' rear
part o' t' fuselage as I can see a little bit o' damage there. Then t' rocket came down, ever so slowly, shiver me timbers, matey, fluttering
to t' ground. I was so mad! That wasn't supposed t' happen. Aye aye! Avast! But I have heard that Estes engines, which are what I
used, can have an overly energetic ejection charge. Avast! I'll have t' reinforce it with somethin' next time, if thar be a
next time. Oh well, me bucko, me bucko, I pretty sure it's repairable so I'll get on that.
Recovery:
It went up so straight that t' two broken pieces landed within 15 feet o' t' launch pad!
Flight Rating: 2 out o' 5
Summary:
I feel that Semroc has made a very good kit with easy t' follow directions. Aye aye! Arrr! T' balsa might just be a little bit too
weak t' handle t' forces o' rocket flight though. Ya scallywag! Blimey! I am goin' t' try some o' Quest's engines in it and see what
happens. Although it may have that one problem I'm sure it can be overcome somehow so I am still goin' t' recommend it
to you. It is a fun kit t' build and a great thin' t' launch, at least from what I saw.

Brief: A retro boost glider that was purchased for me by my nephew and niece for my birthday. This was the first model rocket that I have built since I had a stroke--and it proved a bit of a challenge. Construction: The kit comes in a bag and contains: motor mount 2 balsa sheets of parts balsa nose cone decal launch lug The balsa was light, ...
Brief: A Retro-Repro production from 1965. The Hawk is a quick to build boost glider that ejects its motor and glides back down. Flies almost from the building board. Construction: Kit comes in a plastic bag and contains: 1 instruction booklet 2 3/32" balsa part sheets 1 BT-20 motor tube 1 Balsa nose cone 1 1/8" launch lug 1 Hawk decal ...
Brief: The Semroc Hawk RetroRepro boost glider is a very simple to build and easy to fly rocket boosted glider. Based on the 1965 AMROCS Hawk, it ejects its motor to establish a stable, balanced glide. Construction: In the well packaged kit you get: 1 Instruction set 2 3/32" balsa part sheets 1 BT-20 motor tube 1 Balsa nose cone 1 1/8" launch lug ...
Brief: This is Semroc's Retro-Repro kit of the 1965 AMROCS Hawk. It is a swept-wing boost-glider that uses motor ejection to change CG at apogee. Construction: The kit consists of a balsa nose cone, an 18mm motor tube, a launch lug, a waterslide decal, and two sheets of laser-cut balsa parts. The instructions in this Semroc kit were well written, logical, and generously ...
Brief: I put my order into Semroc during their end of the year Christmas discount. My order was already over $40.00 and the Hawk was a free kit! I added an extra Hawk to my order. One to build, one to hoard. I had an AMROCS catalog in the early 1970s. I remember thinking it was a near twin to the Estes Falcon. With laser cut fins, this kit went together much easier than my ...
Brief: Near reproduction of a boost glider (BG) kit from 1965 made by AMROCS. This is a forward motor BG which changes from boost to glide by ejecting the motor casing, shifting its CG to the rear for gliding flight. Construction: This kit contains: (2) Balsa fin sheets - laser cut Nose cone - Balsa Motor mount 18mm Launch lug Decal Construction was ...
Brief: The Hawk was originally introduced by Advanced Model Rocket Systems (AMROCS) in 1965. Its design is very much like the Estes Falcon. It's technically a boost glider, although it doesn't use a carrier vehicle, instead relying on ejecting the motor to handle the necessary shift in CG/CP relationship. This Semroc "retro repro" faithfully reproduces the original ...
