About this template

Cut and fold two original paper helicopters, using solid cut lines, dashed fold lines, three equal body panels and opposing rotor folds. Starter compares 150-unit and 210-unit blade lengths while retaining the same body, paper, clips and release height. Growing offers three equal-tip trim choices on the longer rotor. Release both together at standing-hand height over a clear floor, without pushing, and record the first down and whether each spins across three trials. Adult cutting and assembly help are required; actual flight results remain open.
