Abstract: An electric motor toy transport trailer configured to transport an electric motor toy 21 includes a charger 17 includes a rechargeable main power source 17a and a charging connector 17c connected to the rechargeable main power source 17a via a cord 17b. The rechargeable main power source 17a is housed in the electric motor toy transport trailer body 12 in a manner such that the rechargeable main power source 17a is disposed at a position lower than the upper edge of tires 13. The charging connector 17c is stored in an openable and closable container box 14 provided on the electric motor toy transport trailer body 12.

Abstract: A toy boat includes a screw 29 driven by a driving source 26, a screw bracket 30 configured to support the screw 29 and function as a rudder, and a servo mechanism 31 configured to turn the screw bracket 30 towards a horizontal position. The driving source 26 is mounted on the inner side of a boat body 22. The screw 29 is connected to a drive shaft 27 by a universal joint 28 on the outer side of the boat body 22, wherein the drive shaft 27 is driven by the driving source 26. A screw adjustment mechanism 38 configured to adjust the angle and depth of the screw 29 is provided, wherein the adjustment is centered around a connection part 28a connecting the universal joint 28 and the drive shaft 27.

Abstract: Multi-cylinder two-stroke radial engine, specially intended for use in models with a cubature in the order of 0.30-1.20 in3 and particularly for model aircraft applications. It comprises (FIG. 1) a cylindrical body (1) on the perimeter of which there are radially positioned cylinders (2) inside which travel pistons (2a) connected by means of connecting rods (6) to a configuration of an equal number of crankshafts (8a) that pass through the cylindrical body (1) and their gear wheels (8b) engage with a gear wheel (3a) of the central axis (3) in the interior of the body (1), which comprises the crankcase of the engine and is structured in such a way that the desired compression is achieved.

Abstract: A model engine starter assembly is provided which is capable of quickly relieving the engagement between the actuator and the coupling pin upon the start of the model engine and includes a starter shaft which carries a starter pin and defines a shaft axis, and a hub provided with a guide groove which is slanted at a predetermined angle with respect to the shaft axis. The hub has a bore in which a rearward end portion of the starter shaft is inserted for rotational movement relative to the hub. The starter pin is received within the slanted groove so as to move the starter shaft in the direction of the shaft axis in response to rotation of the shaft axis relative to the hub to thereby move an actuator attached to a forward end of the starter shaft into and out of engagement with a connecting pin of the model engine's crank shaft.

Abstract: A gear system having a gear installed with shock absorbing means in a model engine starter. Said gear system comprises a rotary drive section to generate a turning force; a hub formed with an inclined guide groove axially slanting at a predetermined angle; a starter shaft having a pin mounted at an intermediated portion thereof and an actuator at one tip end thereof, said starter shaft being inserted through said hub to be guided by said inclined guide groove to move said starter shaft such that said actuator is brought into engagement with a model engine crankshaft: said gear system comprising a final stage gear loaded with shock absorbing means therein to absorb an impact upon engagement of said actuator with said model engine crankshaft.
