Engine Front-mounted Rear-drive Model Airplane

Abstract

The invention provides an engine front-mounted rear-drive model airplane, the frame of which is composed of a generating lifting device, a framework and a lower bracket, wherein the framework includesa control circuit board, a power source and a main framework, the main framework includes an upper part of a main framework; a hollow cavity chamber and a main bracket which are formed at the lower part of the main framework, the control circuit board and the power source are electrically connected and accommodated in the hollow cavity; compared with the current technique, the engine front-mounted rear-drive model airplane provided by the invention adopts the structure of a main propeller and a secondary propeller, and the main and auxiliary propellers can rotate in opposite directions so asto overcome the defect that the flight of the engine front-mounted rear-drive model airplane is unstable due to the one-way force.

Description

technical field [0001] The invention relates to an electric toy, in particular to a vertical lift aircraft. Background technique [0002] Model airplanes with front-engine and rear-drive engines have been loved by people since they came out. In order to meet the needs of consumers, toy manufacturers continue to develop various model airplane models with front-engine and rear-drive engines and continue to improve them in order to create a stable Flyable and easy-to-control model airplane with front-engine and rear-drive. At present, the model aircraft with front engine and rear drive on the market generally have the problem of unstable flight and difficult to operate. The main reason for the unstable flight is that the propeller produces a one-way force from rest to rotation during flight, which causes the engine to be front and rear drive. The model aircraft cannot maintain a balanced state during flight, making the flight unstable. It is not suitable for operation because...

AI Technical Summary

Problems solved by technology

At present, the model aircraft with front engine and rear drive on the market generally have the problem of unstable flight and difficult to operate. The main reason for the unstable flight is that the propeller produces a one-way force from rest to rotation during flight, which causes the engine to be front and rear drive. The model aircraft cannot maintain a balanced state during flight, making the flight unstable

It is not suitable for operation because the steering mechanism of the model aircraft with front engine and rear drive on the market mostly adopts the tail steering structure, and the steering control part and the flight control part are not together, which makes the operation more difficult

[0003] In addition, the lower bracket of the model aircraft with front engine and rear drive on the market is mainly a tripod structure without rollers. The biggest disadvantage of this structure is that it is poor in safety.

When the model aircraft with the front engine and rear drive lands, there is often a large forward momentum, and because the model aircraft with the front engine and rear drive does not always land perpendicular to the ground, the lower bracket is easy to cause the engine Model plane with front and rear drive crashes
