Gday Legends,
I started sup foiling a few years ago on a slingshot h4 foil (1500cm now called surf skate) on a modified 8' sup. Been lifelong surfer and sup rider now for last 7 years. It was set up in position b and got a few rides on waves. Had some surgery and the foil hasn't been touched in years till now after I bought a new echo 6m wing. I've also put on more weight and now right in 100kgs

I've now purchased a latest 6'4 Konrad glidr sup (138l float) and tried with the h4, position b in mid track with 60cm mast in 20 kts last week and could not get up on the foil. Never even felt like it wanted to fly. I've just purchased a i99 (cheers pacey) and looking forward to its arrival and hopefully get my foiling grove on. Also I'll still only have the 42cm rear stabiliser to use with the i99 as funds have run out atm to buy a 48cm rear.

I've been watching many vids and guess there's many options to take but just hoping you guys with plenty of experience can give me a starting position how to assemble foil with i99 and where to place in track on Konrad 6'4 glidr to start getting some lift and adjust from there for foot pressure etc. cheers as always.

I use the i99 might be some useful info on my youtube video,

I foil well on the 99 and the 84 but cannot wing at all on the 76. Just doesn't feel like its going to lift and that also in high winds.

Geoff, what length fuselage do you have? If its the short one, you will need the 48cm stabiliser, if you have the long fuse the 42cm stab will be fine.

you want to position the foil so that its centre of lift is about 40% of your stance width forward of your rear foot, when you are standing in a comfortable position on the board. You don't want to have to move back or forward on the board as you transition from slogging mode to flying. A good place to start is probably at the front of the track if you are using the mast in position A, or about the middle of the track if you are using position B. If the board is reluctant to come up on the foil, move the foil forward in small steps until it wants to come up.

as you get better at pumping you will find an integral part of this is periodically pushing down on the board with your feet, and foils like the i84 and i99 may need more push down with the rear foot to engage the foil and get it to lift. I'd definitely advise starting in a steady 15 knots of wind and flat water if you can find it, light winds or choppy water can really add to the frustration levels while you are working things out.

if you still have trouble after this you can always try shimming the stabiliser to give more downforce. For the 42 stab, which is on top of the fuselage, you should put a washer under the stab at the rear bolt.

Cheers Pacey, exactly what I was after mate. Currently have the 60cm mast but sourcing a longer one now too. I'll double check my feet positions to see where they are compared, but I was using b position in about half the track, and I'll go from there. thanks again mate and looking forward to the 99 arrival and trying it out. I'm stalking auspost tracking daily but they don't update much anymore.

60cm mast is good to start with, you will breach more easily, but you will mostly land the breaches and keep going. I think you get a good awareness of ride height pretty quickly as a result. Most importantly, the shorter mast gives the foil a little less leverage in roll, so its a bit less likely to throw you off if you don't keep your weight over it. I'd do your first few sessions on the shorter mast, before moving up to the longer mast once you feel in control of the foil
