140° 1:1 means that the distance from main mast to the elevator bolt is similar to the distance main mast to aileron bolts when looking from the side on the swash.
In comparance a 120° would have a ratio of apprx. 1:2. So when giving elevator input the aileron servos only have to deflect half of the way than the elevator servo. This can produce a slight collective input because the roll servos will be faster than the elevator servo when giving a control command.
On 140° this is better as the distance shaft-aileron bolts get's wider. But it's still not equal. So most helicopter manufacturers use longer linkage balls to overcome the missing distance and to get the distances equal.
With the Beast X you have both possibilities to choose:
- "true" 140°: three bolts beeing on the same circle, same bolts distances from swash to linkage
- 140° 1:1: the bolts are not on the same circle but geometricaly on a square, saying the distances from center to edges beeing the same.
