THEMA:

I want to be able to programme an experimental land yacht. That works in quite a different way.

I want to have 4 servo's which all have 180 degrees of movement. Of the 180 degrees. I want to use 120 degrees To move the Wheels all in the same direction through the 120 degrees so I can then have fixed sales On each of the side supports. The frame is a diamond shape. With the front and rear servo's. In the middle. Of the central diamond. And the two side Frame supports. Are at 90 degrees to the central. Frame. What I want to do then Is to take the front and rear wheels And use them for steering And positioning of the frame For the fixed sales.

So what will happen is. 120 degrees of the 180 degrees. Will be for positioning of the sails in relation to the wind. And the balance of the 30 degrees each side or 60 degrees overall on the two central servos will be for the steering.

I'm able to achieve the. Sails synchronised And the front and rear servo's. To do the steering working together, But the servo's on the steering will only steer in the same direction, not in opposite directions, which is what I need to do. Hence. I am hoping some geniuses out there. Be able to tell me how to programme. What I want to do into the transmitter. Hopefully the sketch will show you what I need.

The only way. I think it might work at the moment is to have jewel receivers and have one receiver doing the two. Sale servo's on each side. And have a second receiver that does the front and rear servo's and set the receiver too Elevon mix?

There is probably a much simpler way. Thank you for your help.
