Using a slingshot hover glide Infiniti 99 with 48 stabilizer on a outwit board 140L with a 15 inch mass what position would you recommend A,B or C and where should I place the foil on the board 0-10
Currently running The foil in the B position and at 5 on the board
i've been using this set up for two weeks now and cannot achieve flight at all.
I have experimented moving The mass forward and backwards and try the A positionon the foil with no luck
any advice I'm about to throw this in the trash.

Are you stepping back when pumping?
Move front foil forward until it flies too much, the moderate.

Sorry, THEN moderate by moving it back.

B position fully forward would be lots of lift. Move the plate rearward if too front foot heavy.

What wing and how much wind? Have you tried towing it first?

Yes I have tried towing. In the B position at the 5,6,7 Settings on the board. I can get it to fly There but at 15+Mph on the boat !? And the board is nose up. Trying to level just sense the board back into the water and stops flying. I am using a 5.4 In 15 to 20 mph.

When you move the foil forward you achieve more lift. If you're over foiling a lot then try moving the foil (foil's mast) back an inch or two in the track to moderate the lift. Wind strength will help determine where you place the foil's mast in the track or if you have a smaller wind wing you can use it for higher winds and a larger wind wing for lower winds and leave the foil in one spot.

You may have to move your rear foot back a bit to get flight but if you're going too slowly the board may prematurely lift causing it to stall. To counter the stall you can pump the wind wing like hell to bring the board up to speed and over the "hump" -- the board will then gain speed, level out and get properly on foil. Better yet, keep your back foot a little more forward and pump board and wind wing so the board will gently lift due to the increasing board speed. This way you avoid any potential stall.

Have you got the 48 stabilizer the right way up? It goes the opposite way to the 42 stab. The 48 wingtips should curve down.

Also try using a longer mast such as a 24", as a 15" wont give you much scope for flying. With an i99, position A with the mast at the front of the box should give reasonable results for winging

Yes the 48 is wingtips down. I started with the 24 inch mast it was suggested to me to try the 15 " mast Learning it's a little more forgiving.

What fuselage length are you using?

also what wing size are you using, do you have enough sail area?

I am using a 5.4 sling wing in 15 to 20 mph winds. As for the fuselage I'm not sure that's what came with the i99 and a set. it only have A and B steering if that's helps. I'll have to measure it.

I'm about 7 sessions in on an Infiniti 84cm - 48cm Stabiliser - B position, on the 71cm mast (28"). I'm on a Naish Hover 110L for the board, and on an Echo 5m wing - around 80kg.

I initially started with the foil mounted all the way forward as I had seen suggested in many places, but I found the foil acted exactly as you described behind the boat - where if I managed to get the foil flying, it would be flying in a 'nose up' attitude, and would quickly completely stall out and the board would fall back to the water.

The problem was that the foil was way too far forward. I have now moved the foil almost completely to the back of the Naish tracks, and even then, I'm only just on the verge of being able to have my front foot where the foot-straps are supposed to be (I'm not using the straps at the moment).

I can get going in around 12 knots, but it can be a bit of a struggle at the lower end. By 15-16 knots though, it pretty much jumps up on the foil by itself. The Infiniti 84 can be almost standing still in jibes, and it doesn't stall out - the only time I have experienced the stalls was when I initially had the foil way too far forward.

My first 2-3 sessions completely sucked, because I thought 'pumping' the wing meant trying to force the board to get up to flying speed, and then 'pumping the foil' with your back foot so the foil will take off (as you mentioned getting up to takeoff speed behind the boat). That is extremely difficult to do, especially in marginal wind. What changed everything for me was seeing a video where a guy showed a technique where he is basically trying to get all his weight off the board, so the foil can lift itself and the board out of the water (so you are using the Wing to take as much of your weight as possible, while also getting some lateral speed). Once the board comes out of the water, then you can pump the foil and use the Wing to give you further momentum across the water. Once I started doing this, anything over 12 knots became reasonably easy for me to get going in.

With the Infiniti 84cm, once it has risen like that, it's almost like having a platform under you, so I imagine the 99cm is going to give heaps more.

This was the video I was referring to above - he went even further where he was using the 'pop' from submerging the board to lift the foil out. www.seabreeze.com.au/forums/Wing-Foiling/Wind-Wings/Low-wind-foil-Winging-on-lakes

Keep at it... It's definitely worth it, and your gear should be fine once you sort out where everything needs to go. Obviously, your board is different to mine, so I'm not saying you need to move your mast right back, but the symptoms you were describing sound similar to what I was experiencing.

Update I moved the mast Forward to about 1 inch of max and I tried and tried and tried with no luck. I then move it another inch towards the stern and try pumping And pumping and pumping. I was about to give up after two hours of this. A Gust came through And two pumps the board just came out of the water and foiled all the way across the Bay approximately a quarter of a mile. All I had to do was stand there with a wing in my hand. Of course I could not achieve this again for the rest of the afternoon but there's always tomorrow??
Thanks again for every ones advice.

Something about the i84 and I think the i99 wings is that they need a bit of a push down with the rear foot to engage and lift out, whereas other foils that I have tried such as the i76 or the Armstrong 2400 just seem to come up by themselves. Whether this is just that they are not set with enough angle of incidence relative to the bottom of the board I dont know, but it is definitely an idiosyncrasy of the i84 which I use all of the time. Doesn't stop it being a great wing however

Stoked for you

I'm new to this as well but have an intermediate windsurfing background. I suck at pumping but try to read the gusts so start out, slog slowly upwind watching the water, spot a gust, bear away a little (windsurfing term but basically means pushing on ure tops and pointing the nose of the board away from the wind), couple of pushes on my back foot and up it flies.

That and plenty of wind helps also, my first few sessions I was waaayyyy overpowered on a 5m duotone wing when flying but it just makes it so much easier to get going.

Once you get the knack you will be loving it - I know I am hooked!

This is where he does the 'cork' thing. He is going in Crazy light wind on a small volume board (but massive wing).
