The Sonda II B is the largest of Brazil's series of Sonda II sounding rockets. The Sonda II was first flown during the early 1970s and continues in use today. 

Ease of construction and painting makes ASP's model of the Brazilian sounding rocket a great first scale kit.

Model rocket kits require assembly. Tools, glue, and paint (not included) are usually required to complete the kit. A motor, igniter, launch controller, and launch pad (not included) are required to fly the rocket. Adult supervision is required during the construction and flying of model rockets.

Model rocket kits are often described in terms of their "Skill Level" - a number (usually 1 through 5) which represents the difficulty involved to construct, finish, a fly the kit. A Skill Level 1 kit requires little or no experience building model rockets while a Skill Level 5 kit requires much experience and special skills.

For the kits we sell, we use a normalized Skill Level using a scale of 1 to 5:

Skill Level 1 (Beginner) kits are easy to build. They usually include pre-cut fins and simple-to-follow instructions and require no special skills to build or fly.

Skill Level 2 (Experienced) kits are usually a little harder to build than Skill Level 1 kits. Sometimes they require that fins be cut from supplied stock. A Skill Level 2 kit may present new challenges to a beginner such as requiring shaping of fins or wings or flying on a larger motor.

Skill Level 3 (Advanced) kits may include instructions which assume that the builder has experience building rockets and does not need as much explicit instruction. They often include features, such as paper shrouds, which require more skill to construct.

Skill Level 4 and 5 (Expert) kits are designed for experienced modelers and present the greatest challenges. Skill Level 4/5 kits are often scale models which require the builder to craft details and carefully mask areas to be painted.

You may also see kits with Skill Level 0 (zero). ?These are Ready-To-Fly (RTF), Easy-To-Assemble (E2X), and Almost-Ready-To-Fly (ARF) kits which require little or no assembly or finishing. Usually, you can take the kit out of the box and it's ready to prep for flight. Even if labelled "Ready-To-Fly," some RTF kits do require a minor amount of assembly, such as attaching a streamer or shock cord.
