Model helicopter has cooling mechanism blower integrated in transmission gear for effective system cooling

摘要

The model helicopter has a cooling blower mechanism integrated in a main transmission gear (1). The mechanism is fitted into an aperture in the helicopter body (3), which is shaped to partially or completely enclose a cooling blower ventilator, so that an airflow (4) is sucked-in from above and passes through the body contour to the parts to be cooled.
