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, strong, and very good quality.

One of the problems that I have had since my stroke is that I find it difficult to read and understand what I have just read. Also, diagrams are hard to follow. I see things drawn in 3D as 2D. Having said that, this was a well laid out set of instructions with good diagrams. The only mistake that I made was that I could not "see" the dihedral on the wings and glued then in flat. My brother took them off later and reset them.

Finishing:
I have only flown her naked so far so there has been no finishing yet.

Construction Rating: 4 out of 5

Flight and Recovery:
The first flight was on a A8-3. She boosted straight and high. At ejection, the Hawk flipped in the air and nose dived in fast. I had not glued the nose cone in! (I had read the part about not gluing it in and not gotten the part about gluing it in!) However, the glider was undamaged and I found the nose cone.

After a quick field repair, the second flight was made, again on a A8-3. At ejection, the rocket split it two; both parts came tumbling down.

Semroc Hawk When I got both parts back, it was clear that the balsa had failed and not the glued seams. I'll repair her and I'll add a hole in the motor mount to vent some of the gases from the Estes shot gun ejection charge.

Flight Rating: 2 out of 5

Summary:
I have seen other Hawks fly and I like them. I think I was just unlucky with my second flight.

Overall Rating: 3 out of 5

  • Semroc Hawk By Tyler Jones (March 29, 2009)

    Brief: The Hawk is a boost glider that uses a rocket engine to get itself in the air. It is a "Retro-Repro" of an older rocket. Semroc is selling them for $7.50 right now so I decided to pick one up. Construction: When I bought the kit I figured there wouldn't be very many pieces. I got it and found only 5 parts in the whole kit. It comes with: 1 BT-20J ...

  • Semroc Hawk By Matt Gillard (March 22, 2009)

    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 ...

  • Semroc Hawk By Robert Gustin (March 12, 2009)

    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 ...

  • Semroc Hawk By Jim Bassham (March 7, 2009)

    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 ...

  • Semroc Hawk By Hans "Chris" Michielssen (February 7, 2009)

    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 ...

  • Semroc Hawk By Howard Smart (January 31, 2009)

    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 ...

  • Semroc Hawk By Chan Stevens (January 3, 2009)

    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 ...
