Has anyone tried this. I have a starboard 109 Evo fuselage (equivalent to older 115) that I have used with an 880 and 725 front wings. My favourite setup tho is the 560 front wing/ 180 rear wing on the 99 Evo fuse, but only usable with a decent amount of wind. im wondering what it would be like putting the small wings on the long fuse? Front wing position is a lot further forward. I'm wondering if it would help in light winds and/or point up wind better.
let me know your experience if you have tried a similar setup before. If not ill try it and report back. thanks
I've used the 650 and 725 on the 115+.
Usually now I wait for the wind to pick up and use 550, 650, or 725 on the 105+ fuse and leave the 900 on the 115+.
You get a little bit of light wind benefit with the longer fuse but you have to be careful on pushing hard upwind on the small wings as they start to get really squirrely when you try to point hard. I think you get high VMG for a little bit then slow down too much to ride comfortably at 45deg or whatever you can do with a larger wing. You can really go deep downwind with the long fuse on the smaller winds but it's not optimal for high speed reaching. I've only used them with the 255 rear.
Thanks - that's what I figured, the small wing will start to stall on the long fuse being really far forward.

It's not a function of the fuse length that causes the stall but the smaller area of the wing giving you a lot less wiggle room for changes in wind velocity. Hard up or downwind are the "slower" angles that we take even though going upwind has a high apparent wind. That's why we use the bigger wings for VMG types of sailing whether course racing or going places. fwiw, fuse length is limited on a lot of true slalom kit more from the leverage the longer fuse exerts on the very fine profile masts used at the pointy end.

I been using my SB slalom 650 front wing with the 115 plus fuselage and 255 stab without problems. I like that combo better than with the 105 fuselage because I can point upwind. I mainly mow the lawn but I don't like just back and forth in the same spot. I feel that the 105 fuselage requires to be very overpowered to be able to point upwind. Btw, the 115 is longer than the 105 but the front wing is further forward and that is what allows you to point upwind aka more powerful fuselage (I think)
I would like to know the difference in windstrenghts between the shorter and longer fuselages in getting on to fly?...would appreciate it.

I don't have a satisfying answer to that but I did notice:
*Adding shim on the shorter fuse vs. the longer fuse helps a lot
*Shoving the sail mast base really far back helps
*Using a smaller sail with less MBP makes a noticeable difference
I was using a 9.0 HGO in just about everything for a while but that thing has a lot of downward MBP vs. the 7.0 or 6.0 foil glide. Regardless, it helped a lot to go +1.0 on the shorter fuse if it was light. Usually if I have the 7.0 on it, it's windy enough for me to use a +0.5 but I also move the mast base pretty far back. I judge if the mast base is far enough back by how well it behaves in the jibes (does it dive a lot). Honestly +1.0 might be better to use for me until it gets to 6.0 weather but I'm a bit lazy in swapping shims sometimes.
@aeroengr - by shimming "+1" you mean adding decolage? (More stability, less speed, more front foot pressure)

Yes. I have the (-2) wing so the +1 is the largest stock shim I have to add lift/front foot pressure.
Mast base back, positive tail shim, less MBP all give better takeoff and upwind performance for light wind slalom fuselages. If the board is set up for the long race fuse it's going to be out of trim for the slalom fuse in all likelihood.
