Students in middle school and up, can learn about aeronautics and problem-solving while they build a complete model from provided kit material and then test how it flies around the PowerPole™. Model planes are evaluated on their speed (rpm), how much load they can carry, and how high they can fly. Airplanes can now be designed to fly faster and higher, controlled by the operator, with no time limit. Includes PowerPole™ and [2] balsa plane kits. Requires a variable power supply (842639). Use safety glasses.
