These custom props are specifically designed for use with three-bladed systems - do not expect them to function effectively with two-bladed props. In my experience, using an FSK 9x7 prop as the primary blade and a GWS 3-bladed reverse prop as the counterweight yields excellent results. Each set weighs approximately 7 grams; recent revisions have brought this down to 4 grams. To secure these props, simply superglue them directly onto the original propellers for an effortless installation process with minimal risk of failure. Instructions: Print these custom parts at a speed of 50 mm/s using high-quality eBay PLA on a reliable Printrbot simple metal printer. Once printed, smooth out any imperfections by sanding down the surface first with 80 grit and then with 180 grit. Finally, gently apply a small amount of oil to achieve a professional-grade matte finish that enhances their aesthetic appeal.
