does riser length effect trim?

[jcbfly 1]

If you put a longer set of risers on a canopy would it move the CG further forward and therefore make the wing trim faster?

By CG I mean the CG of the pilot/wing combination, not just the CG of the pilot or the wing.

No, but it will affect the recovery arc. Shorter risers will reduce, and longer will extend the recovery arc.

Short-lined canopies like a Stiletto 120 have 10 feet of line. A manageable difference in riser length like 4" is about 3% of that. I'd be surprised if it made much of a difference but accept big differences in feel or being able to crank the risers farther.

It will:

1) flatten the chord by increasing the distance between the A/B and C/D lines

2) reduce the cathedral by increasing the distance between the left and right risers (assuming a large, split or removable slider)

However, those effects are really, really small overall.

The most important effect of the long Riser is more Power if you at the Frontriser pulls. With a long arm you have more Power. In addition, the other reasons.
