Oli, can you help me with this please? I am getting bizzare numbers and diagrams playing around with the inner flaps tab - I am using that one to get the assistance with what each cell means. Since flaps only travel downwards I always built the horn at a raked back angle but the spreadsheet seems to assume that the horn must be at right angles to the flap and I can't find a way to apply a rake angle. Even worse comes with the servo, the spreadsheet puts the servo arms and control rods at bizarre angles. Is there a box where I specify the neutral rotation angle of servo? The angle of the yellow line to represent the servo neutral angle, as chosen by the spreadsheet seems very odd. I am sure I must have missed setting a servo neutral value somewhere but I can't find any box that works!
Also can you explain what the black line is showing?

Hi Harry,
The program is finding the offset required for the intended travel. You can play with the servo neutral position by changing the servo travel values.
Here the Rs+/Rs- values.
Instead of the +45/-45 you inputed, I would suggest you to try +0/-90.
The black line shows the 0% stick position.
The rake angle can be simulated by changing the Xc value to what you need.
Let me know if you get what you want that way...
OLi.
