Another good choice to start with mid-power models.
The IQSY Tomahawk is a rocket for E, F and G motors that you can use to start practicing with these engines and as the next step after smaller rockets.
It is a replica of a sounding rocket from the early 60s, the acronym IQSY means "International Quiet Sun Year" a solar activity observations and studies program which has seen the participation of 70 nations in 1964 and 1965.
This version of the true Tomahawk was actually used only a few times, but as a model rocket it was a success to the extent that any manufacturer has had it in his line of kits at least once.
The IQSY Tomahawk has the characteristics of all other Aerotech rockets: plastic molded, pre-finished fins, blocked by the integrated system which allows a perfectly aligned assembling, the permanent protection for the parachute installed inside the motor mount, the aluminium screw-on motor retainer and the included adapter for 24 mm engines.
The Tomahawk, like many other models Aerotech, has a payload section useful to install micro cameras or other payloads.
The motor mount tube is 29 mm, but with the included adapter is also possible to use 24 mm motors. In both diameters the engines available are so many. A model of this size flies very well with F engines, both 24 mm and 29 mm, single use and reloadables. You can also launch it with E engines, and if you are a daredevil you can also try a G engine, but it will probably be the last time you see your model ....
To launch this rocket you need a 6 mm launch rod, and a 12 v launch controller. We suggest Aerotech Mantis launch pad, the Estes PS II launch pad or Klima Launch Pad, and Aerotech Interlock Launch Controller, Estes PS II Launch Controller, or the Universal 6-12 volts Launch Control.
Aerotech kits have a complete set of solutions and construction details that brings them one step beyond all other mid-power kits of the same size. For this reason, and for the great care with which they are made, they appear to cost more than others, but being so complete does not require the purchase of additional parts, and to finish them you need only adhesive and colors.
Opening the box of one of these kits you will immediately notice the quantity and quality of the parts. The tubes are made of strong kraft cardboard, with pre-cut fins slots. The nose cone is tough plastic, with a length to diameter ratio of about 5: 1.
But certainly the most striking particular is the motor mount assembly and the fins. These are made of rigid and molded plastic. You do not need to sand or give them an aerodynamic profile. They fit into two grooved plastic rings that keep them perfectly aligned and blocked at the same time. No more crooked and misaligned fins!
In addition, the motor mount tube has a pencil line traced on it that acts as a reference for mounting.
Another unique feature of the Aerotech kit products is their parachute protection system, made with a steel mesh which filters and cools the ejection gases, preventing them to damage your parachute. Before reaching the parachute the gases are forced through the holes of a plastic closure which also acts as an anchor for the shock cord.
This way you do not need to add any protective wadding or similar materials, and the rocket can be prepared to fly very quickly.
Even the motor retainer is worthy of note. Initially, these kits were equipped with a steel engine hook, similar to those present in Estes kits but bigger and stronger. Now Aerotech has made a screw-on motor locking system that is included in all their kits.
If you add the cost of such a retainer and a parachute Nomex protection to the price of other kits comparable in size, you easily see that the Aerotech kits are very competitive.
A nylon parachute of appropriate size, a self-adhesive decals sheet of excellent quality, and launch guides for 6 mm rods are included as well.
The shock cord is made of fabric covered elastic. This is perhaps the only detail that we would improve. Although abundant in length, elastic is not the ideal material because it can break in the long run. As it is tied to the motor mount, it will be difficult to replace it. For this reason, we would add some 3 or 6 mm Kevlar tubular, at least until you get beyond the opening of the fuselage, in order to untie the elastic band if it should break, and replace it with a new one.
