This model can convert any axis red series wing to work with a fliteboard. This model requires four m8 nuts and four m8 washers. these parts are imbedded into the print. the washers at layer 50 and the nuts at layer 82. this is at a 0.2mm layer height. The layer they need to be imbedded in will change depending on your layer height. The first 50 layers must be solid. this will also change depending on your layer height. It needs to be solid up to when you imbed the washers. the part should be printed with the groove facing up. Once printed the adapter is slid onto the efoil where the wing would go. Then use three m6x30mm countersunk bolts to secure it. from there put the wing on top of the adapter and screw it down by m8x25mm countersunk bolts. During my testing of this product, I only tested ASA and the above settings. The adapter did not break or show any signs of stress even when riding aggressively. If your adapter shows any signs of wear and tear, please reprint.
