Not sure Derek,
I have a vry old standard Rev 1 and have flown it in winds I would think were up to 20mph and gusting, at least enough to take me off balance quite a few times. Not quite sure what the standard wrap is for a Rev 1 as my frame is so old as to not have markings. Going by my EXP which is also not marked I would think the standard MIGHT be 3 wrap as I THINK that is what is in the EXP, obviously I stand to be corrected on this.
If indeed it is a 3 wrap SLE dont forget that is a half inch rod and is considerably stiffer, I would not be suprised if it would not be OK to 25 and possibly above. however a Rev 1 has quite a large sail area and it might be too much pressure on the frame at that speed.
I am sure someone will know rather than think!!!!!!!
