@ Pakingzzz, Congrats man!..... Am from South Africa. I heared about you through a couple of Heli members here in Johannesburg. Also saw a bit of your works in a couple of journals online... You'r such a wonderful Engineer. Heli members in South Africa are thrilled by your feat. We'r looking forward to seeing your heli take to the air. We would like to donate and encourage you. Pm me please. 1 Like |

@ Pakingzzz Some Rc members here in Johannesburg would like you to explain how you got the bearing and what holds it. And how you got ahold of the materials you used in fabricating your swashplate? And also,the external circuitry you built to amplify the Pwm signals from your Airhogs Rx,please elaborate and throw more light? |

Gigeadek: my questn is dt, how can d swash plate control automaticaly by radio controller. I jst want u to analys on it and d receiver and transmittr Ok.... To put it in a way you'll easily understand. I shall explain the relationship between them. The relationship between them,is that; the swashplate is connected to the servo. The servo is connected to the Rx. The Rx recieves pwm signals sent from the Tx. There's a component you missed. The servo. The servo is a device that converts pwm signal into mechanical movement. Simply put. A Servo is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo pwm signals. As long as the pwm signal exists on the input line, the shaft of the servo will maintain a certain predetermined angular position. As the pwm signal changes, the angular position of the shaft changes. The Tx has a joystick. The Tx transmits a pwm signal. When the position of the joystick is changed. The pwm signa also changes. This change is directly proportional to the position of the joystick. When the Tx transmits,the Rx receives this signal and demultiplexes the signal to the various channels. The servo receives a pwm signal from one of the channels in the Rx. It then uses this pwm signal to move it's output shaft to a certain angular position,determined by the current pwm signal it is receiving at that instant. The swashplate is connected to the output shaft of the servo,through a crank setup that converts the servo's output shaft angular movement into a linear movement(up and down movment,in this case) This is the relationship that exist between these devices. 1 Like |

@ Gigeadek, Below is an animation picture of a servo. NOTE!!: The black screw you see rotating from a clockwise direction to an anti clockwise direction is the output shaft. The black arm you see moving from left to right is the crank setup. The movement it does,from left to right is technicaly called a 'linear movement'. So you now see,how the black arm simply converts rotary movement into a linear movement?

If you feel like looking up the technical details. You can click here: www.rcgroups.com/forums/showthread.php?t=2008350 The documentation there is more up to date than the documentation here. With more step by step pictures of the helicopter construction. And also some links to some youtube videos,featuring the explanation of most critical components. 1 Like |
