Abstract

A remote control helicopter includes a body, a tail wing, a rotor assembly, a landing skid assembly, and a charging port on the bottom of the helicopter. The remote control for the helicopter includes an outer housing, landing skid grooves, a power switch, a throttle control stick that controls the ascent and the descent, a direction control stick that controls the turning or rotation of the helicopter, and a charging plug.

First claim

The invention claimed is:

1. A toy helicopter with a remote control, comprising:
a power source of the remote control;
a first charge connector on the remote control;
a face of the remote control, the face forming a first landing skid groove and a second landing skid groove;
a main body of the toy helicopter;
at least one rechargeable battery housed by the main body;
a second charge connector on the main body capable of connecting to the first charge connector on the remote control;
a rotor assembly having a main shaft and at least one rotor blade, the rotor assembly connected to the main body;
a landing skid assembly connected to the main body;
a first landing skid of the landing skid assembly, the first landing skid capable of fitting into the first landing skid groove; and
a second landing skid of the landing skid assembly, the second landing skid capable of fitting into the second landing skid groove;
wherein when the toy helicopter and the remote control are in an attached position, the power source is capable of charging the rechargeable battery.

2. The toy helicopter of claim 1 , wherein the first landing skid and the second landing skid are on opposite sides of the second charge connector.

3. The toy helicopter of claim 2 , further comprising:
a catch rail on the rotor blade capable of engaging with a rotor blade grip of the rotor assembly without use of additional fasteners or tools;
wherein when the catch rail and the rotor blade grip are in an engaged position, the catch rail remains engaged with the rotor blade grip during operation of the toy helicopter.

4. The toy helicopter of claim 3 ,
a plurality of first clip elements on the main body; and
a plurality of second clip elements on the landing skid assembly, the landing skid assembly forming a hole through which the second charge connector can pass;
wherein the main body is molded into one piece;
wherein the landing skid assembly is molded into one piece;
wherein the landing skid assembly helps support the second charge connector; and
wherein the first clip elements are capable of being attached to the second clip elements without use of additional fasteners or tools.

5. The toy helicopter of claim 3 , wherein the catch rail consists of a catch hook and a blade head forming a curved slot with an open end;
wherein the rotor blade grip consists of a grip rod sandwiched by two grip plates, a first grip plate on a top end of the grip rod and a second grip plate on a bottom end of the grip rod;
wherein the grip rod is capable of sliding into the curved slot; and
wherein when the grip rod reaches an enclosed end of the curved slot, the catch rail will be secured to the rotor blade grip.

6. The toy helicopter of claim 1 , wherein when the first landing skid is not secured onto the first landing skid groove, the first charge connector is prevented from connecting to the second charge connector.

7. The toy helicopter of claim 6 , wherein when the first landing skid is engaged with the first landing skid groove and the second landing skid is engaged with the second landing skid groove, the first charge connector is aligned and is in contact with the second charge connector.

8. The toy helicopter of claim 1 , wherein the first landing skid can only be secured onto the first landing skid groove when the first charge connector is connected to the second charge connector.

9. The toy helicopter of claim 8 , wherein when the first landing skid is engaged with the first landing skid groove and the second landing skid is engaged with the second landing skid groove, a first top peak of the first land skid and a second top peak of the second landing skid are approximately flush with a top side of the remote control.
