Great info thanks Marek.

With my + fuse, I am very close to the mast cutout if I maintain a 71mm space between the saddles. (Roughly 0mm between the mast cutout and the new saddle cutout)

Do I risk that either (1) the aluminium sides are strong enough at the mast cutout or (2) do I cheat and shrink the distance between the wings say from 125mm to 95mm (would give me about 30mm between the mast cutout and the new saddle cutout)

It looks like Marek has ~ 50mm between the mast cutout and the new saddle cutout.

Edit: AI says 30mm is the minimum I could go

Looking into this further.
I have a 900 & 800 front wings.

1. Marek - can you compare the takeoff speed of your dragonfly vs slingshot i99 (I used to have a i99 so I can relate to that takeoff speed)?
I understand that the dragonfly will be faster but I am wondering about takeoff speed. From your graph it looks like the i99 takeoff is a touch earlier?

2. I have the + 115 fuse. Should I still use 71mm space or could I reduce the gap? (photo below with 71 mm space)

3. How does it turn? Does it move the centre of lift back somewhat? Any weird control issues?

4. I would probably 3d print a spacer to put back in if I wanted to run it as a single foil.

Thanks!
Joe

I have an iq foil (900 front) and sail it on a sb 177 foil board.
I haven't been exactly happy about the low end - this does gets me a thinkin - a 900 and my extra 800 wing together...

Who do i know that has a cnc machine??

Casey at Reef Warriors is making some great foil boards.

Mine is ~4 yrs old with ~150 sessions and is like new.
