Model engine axle end start converter

A model engine axle-end start converter comprising:

• a converter package;
• the converter package containing a replacement start shaft, an adaptor plate, fasteners and assembly instructions;
• the replacement start shaft being articulated to replace an O.S.® pull-start shaft on an O.S.® model engine and to receive a Traxxas® one-way clutch on an axle end of the replacement start shaft;
• the adaptor plate being articulated to position a Traxxas® electric starter on the O.S.® model engine for use on a Traxxas® model truck;
• and
• the fasteners being attachment bolts having lengths and machine threads for fastening the adaptor plate to the O.S.® model engine.

A model engine axle-end start converter comprising:

• a replacement start shaft and an adaptor plate;
• the replacement start shaft having a crankshaft end and a starter end;
• the crankshaft end including a crank plate that is collinearly concentric with the replacement start shaft;
• the crank plate having a circumference with a predetermined thickness;
• the replacement start shaft having a bearing portion and an axle portion that are concentrically in line intermediate the crank plate and the starter end of the replacement start shaft;
• the bearing portion extending from the crank plate in a direction towards the starter end;
• the axle portion extending from the starter end to the bearing portion;
• the bearing portion having a bearing-portion length predeterminedly commensurate with a length of a plate bearing on a starter-end plate on a conversional model engine;
• the bearing portion having an outside periphery with a diameter commensurate with rotational bearing contact with an inside periphery of the plate bearing;
• the bearing portion and the axle portion having a combined length that is predetermined to position the axle end and a predetermined length of the axle portion in predetermined proximity to a starter coupling of a predetermined electric starter;
• the crank plate having a crank-axle bay articulated to receive a crank axle of the conversional model engine;
• the crank plate with the crank-axle bay being articulated predeterminedly equivalent to a crank plate with a crank-axle bay of a starting shaft of the conversional model engine;
• the axle portion being articulated for one-way-clutch communication with one-way-clutching members proximate an inside periphery of an external one-way clutch;
• an external one-way clutch having an outside periphery with clutch-coupling shoulders that interlock with an insider periphery of the starter coupling of the predetermined electric starter;
• and
• the adaptor plate including an adaptor thickness to position the starter-end plate of the predetermined engine in predetermined proximity to an engine side of a starter plate of the predetermined electric starter in which the starter coupling is positioned.
