(by Jason Toft - 07/05/04) Thrustline Aerospace Hank

Brief:
A short and fun two motor cluster rocket with 6 fins with a cool military-esque style.

Construction:
THe kit contains:

  • BT-60 Elliptical nose cone
  • BT-60 tube (10.75")
  • Balsa fin stock
  • 2 BT-20 motor tubes
  • Thrust rings
  • Light ply centering rings
  • Launch lug
  • Shock cord
  • BB's for nose weight

This rocket is quite simple to construct and uses many of the features that we rocketeers consider to be the best way to do it. For example, the centering rings are laser cut light ply, the shock cord mount is 'Quest' style, and everything is high quality. In my kit, I used wood glue and CyA for all construction. It is amazingly simple to build. Basically, all you do is glue the motor tubes together along with the thrust rings, attach the Kevlar shock anchor by drilling a hole through the top centering rings, cut and fill the fins, attach them, add nose weight, launch lug, and parachute, paint, and fly! Plenty of everything is supplied in this kit, and you have enough left over to build another, albeit smaller, rocket with the excess.

Thrustline Aerospace Hank The centering rings are laser cut 1/8" thick light ply. They are strong and durable; in my opinion, it is borderline overkill. You could easily go with fiberboard with this motor configuration and have no troubles.

The fins are 1/8" balsa that you have to cut out from a pattern. This is easy to do and if this is one of the qualifications to make this a "builder's kit", it definitely passes. I personally enjoy cutting out fins for kits, as it provides me with a sense of accomplishment.

With this kit, you may get a plastic nose cone or a balsa nose. I got a plastic nose and I think I prefer it over the balsa cone. The instruction have you drilling several holes into the balsa cone and covering it with epoxy, yet with the plastic cone, just drop the weight in, secure it with the epoxy, and go! Easy enough.

Finishing:
I finished this rocket with yellow glue fillets, then use Elmer's Fill 'n' Finish (and sand and sand and sand if you know what I mean) to create some very nice fillets. I trimmed the ends of the launch lug at an angle to make it look better.

Thrustline Aerospace Hank I then used a coat of Krylon Gray primer to find spots, filling the most noticeable ones, and then covered it with a coat of white gloss as a basecoat. The entire model was painted black, then masked off the fins and painted them glossy purple, however, because of the black basecoat, they turned out to be a flatter purple. Remind me not to do that again!

Construction Rating: 4 ½ out of 5

Flight:
For the first flight, I used a pair of A8-3's and the supplied 12" nylon chute. You could easily describe this as a lob flight. The burn on the two A8's is so short that it just barely cleared 75 feet before they burned out. Apogee was at about 150-175 feet, and then it landed about 40 feet from the pad. Great, smooth flight but it needed more power.

For the next flight, I used 2 B6-4s. This time I used a red Rockethead mylar chute and the flight was much more satisfying. Very quick off the pad with an apogee of around 500 feet and it landed about 70 yards from the pad.

Thrustline Aerospace Hank In my opinion, B6-4s are the best choice for this rocket. I have yet to try it on C6-5s, but I think it will be just peachy...and very, very fast!

Flight Rating: 4 ½ out of 5

Summary:
I feel that this is a great little rocket and it makes for a great park flyer on A8s and B6s. As a Skill Level 2 kit, it makes for a good weekend build and is challenging enough to be fun. Thrustline has a great thing going with their new line of kits and I recommend you get this one. It'll be great fun!

Overall Rating: 4 ½ out of 5

GUEST's OPINION:
02/08 - "Great kit! Assembly was simple even with six fins to install. Finishing was straight forward with several coats to fill & smooth the balsa. I made a bad choice with the first paint scheme - a fluorescent pink that flaked off badly. I spent a couple nights scraping the pink off and repainted it gloss white with a gold nose. I used leftover decals from an Estes Bullpup to give it a cruise missile look. First flight on an A8-3 pair was more of a lob than a flight. I had much better results with a B6-4 pair. This rocket is a bit different from the normal lot and received some positive attention from the crowd. It definitely gets noticed for its looks and nice flight profile. Again, another winner from Thrustline!" (G.W.)

Wind Notes
10-17-2009 Matthew Bond 2x Est SU B6-4 Just Past (1-2sec) 10+ mph winds Flight Picture HClone - First Flight of the new Hank! Nice boost, fast and straight. Arcing into the wind at the top of the climb, just past apogee at ejection. Good chute, long walk, grass landing, no damage
11-21-2009 Matthew Bond 2x Est SU A8-3 Apogee - NC Down 0-5 mph winds Flight Picture HClone - Good ignition of both motors. Pretty nice boost for this motor selection. Smooth and straight, not real high, just nosed over at ejection. Good chute, minimal drift, grass landing, no damage.
09-26-2010 Matthew Bond 2x Est SU C6-5 Apogee - NC Down 0-5 mph winds Flight Picture HClone - First flight of the Hank in a long time. Great boost, straight and fast. Arcing over, nose down at ejection. Good chute, short walk, lakebed landing, no damage.
07-08-2006 Keith Hamel 2x Est SU B6-4 Apogee - Perfect 0-5 mph winds - Perfect flight, straight up. B6-4 is an excelent motor for thr Hank.
10-04-2008 Keith Hamel 2x Est SU B6-4 Apogee - NC Up 5-10 mph winds Event: Section Launch-Amesbury
- Great flight straight and high.
06-23-2007 Ron Wirth 2x Est SU B4-4 Just Before 0-5 mph winds - First flight.
11-18-2007 Gene Wolski 2x Est SU B6-4 Very Late 0-5 mph winds Event: Pole Green Park
- Only one engine lit, and the rocket ended up arcing over and dropping near the pad.
