About this model

This balloon helicopter is a neat toy, tool for teaching basic flight physics, and very nice case study in design and experimentation that could be useful in the undergraduate or high school teaching lab. Notes on flying: Current best configuration: 16mm blades (blade_16.stl), 13 degree rotor (rotor_13.stl). Short flying video clip located here: Before you build: Unfortunately, it does not yet perform as well as commercial versions, if you are interested in a set of commercial balloon helicopters, consider one of these or this set seemed rather good Once printed, insert the three blades into the rotor. Insert the nozzle long ways into a balloon and fill the balloon. Insert the nozzle into the rotor while pinching off the balloon, try to ensure that it is straight. Throw. Try different tech…
