A brief but lucid introduction to aerodynamics, kitted up with materials for five ultralightweight flying models.

Supported by clearly labeled diagrams and cartoon portraits of typical and historical aircraft, the explanations of thrust, lift, roll, yaw, pitch and other considerations that must be taken into account when designing even the simplest fliers and gliders will give young aeronauts a good grounding in the basics. Step-by-step directions for assembling the provided models—two hand-launched gliders and three craft driven by rubber-band–powered propellers—are incorporated. Arnold goes on to a discussion of indoor vs. outdoor flights that includes a safety checklist and also suggests some experimental modifications to try out. The booklet closes with a blank “logbook” for recording the results of said experiments, followed by a pair of patterned sheets to cut out and fold into paper planes. This is all bound up with a deceptively large box in which punch-out forms on insubstantial sheets of neoprene and balsa, plus two plastic propellers and some wire, rattle around. Not only is five a paltry number next to, say, the 35 fliers for which Bobby Mercer supplies instructions (if not materials) in his Flying Machine Book (2012), but the paucity of propellers means that the models cannot all be assembled at the same time. Moreover, the balsa is unpainted, and the other pieces are colored on only one side for that extra-cheap look.

Adequate from an informational standpoint: for hands-on engineering, a disappointing demonstration that less is less.
