Abstract

The control mechanism for remotely controlled coaxial double rotary wing model helicopter can meet the requirements for different users to control the model helicopter in different sensitivity, and includes steering engine, lower connecting rod, wobbler with rotating cup and no-rotating cup, oar jig, outer shaft and middle connecting rod. The present invention features that each of the lower connecting rods is connected to 2 or more no-rotating cups and each of the middle connecting rods is connected to 2 or more round heads in the oar jig, so that the present invention has adjustable force arm length of the rocking arm and altered controlling sensitivity. The present invention makes it possible to select different connection position to reach proper control sensitivity.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a control mechanism of a coaxial double-rotor model helicopter. Background technique [0002] The stability of the remote control model helicopter is poor, and it has higher requirements for the control technology, especially compared with the person who has mastered certain control skills, the requirements for the control performance of the remote control model helicopter are quite different; beginners mainly It is to fly the remote control model helicopter smoothly and safely. In order to avoid the slow operation caused by the unskilled control technology, or the flight accident caused by the excessive control action, the sensitivity of the remote control model helicopter is generally set at However, for flight enthusiasts who have already mastered certain control techniques and need to further practice more difficult flight movements, the control performance of the remote con...
