1)Use a good rubber mallet to put on the wings and take them off. You can hit them very hard to get them snug by hitting the leading or trailing edge of the wings. The wings are solid ! The key is to use a very good rubber mallet like the “Dead Head ” brand gray mallet sold at The Home Depot.
2)Tightened the wing screws till they are snug and do not over tightened them too much as the collar is where the actual fit and snugness is achieved, not with tightening the screws tighter.
3)Always tighten tuttle screws very tight though, rake mast back and forth (front to back) and retighten tuttle screws a couple times to get super tight. After riding you can usually tighten tuttle screws even tighter, especially after jumping!
4)Back footstrap is a preference thing, I always like to have it on but many people like to ride without a back one. To get the back strap forward on the 155 and 160 model boards, you can use the tuttle screw that is the longer one of the three and put it through the strap and connect to tuttle base or you can put double screws through the strap and use those places as well in the middle of the two tuttle bolts on the board. Use a screw /drill gun and screw the screws through the strap webbing manually about 1/8″ to 1/4″ outside the standard 2 hole places in the strap with the screw/drill gun. You need to have screws just slightly wider apart in the footstrap than the standard two hole placement so the screws will fit in the hole placement in the board. The inserts are slightly farther apart in the board because the tuttle box is in the way.
5)When first learning to foil, I recommend starting with the straps in the far forward position and move them back from there as you start to get comfortable.
Straps forward equals less lift,
Straps back will give you more lift!
