This 3 piece wing will fit the 1/8 scale, 6s Arrma Kraton, Arrma Typhon, and Arrma Notorious. I included the files for the attachment grommets although the stock grommets will fit as well. You will need longer M3 mounting screws as well as eight 3X8MM screws and locknuts to attach the blades. For the most durable results, this wing can be printed from TPU. For a more rigid wing, I have had great results printing the main wing from CF-Nylon or PETG. The blades work best when printed from TPU. They can be easily replaced when they wear out. This wing doubles as a stable wheely bar. The TPU blades provide a durable skid when pulling a long wheelie. When printing with an Ender 3 this wing will need to be placed diagonally on the print bed. It will need some support structure that is easily removed.
