1. Gforce SUL, 32.5" is correct for LS
2. Both stand-offs should be the same diameter - non flexible. Inner Standoff is 10", Outer Standoff is 9" (total length from sail).
3. US is 21.5"
Thank you pfouts.
- So my lower spreader and standoff lengths are correct! (got mm and cm confused for standoff lengths in the original post - now corrected.)
I think that my 10" standoffs flex partly because the load on them is greater than on the 9" standoffs, and partly because the 10" standoffs are using thinner 2.5mm carbon.
Hmmm, will have to try flying it again. - See if I can pin down the symptoms that suggest it is not set up correctly.
