ABSTRACT:
A combination field box and engine starter for model airplane engines is provided. The engine starter is mounted on the upper portion of one of the sidewalls of the portable field box. The field box includes a bracing assembly on the wall opposite to where the engine starter is mounted for preventing the box from sliding or tipping when pressure is applied to the starter during an engine starting operation. Additionally, the engine starter is provided with a torque enhancing gear train and an over-speed clutch which allows it to start relatively large model airplane engines with power generated by a compact battery pack formed from eight 1.2 volt nickel-cadmium cells.
