RC enthusiasts, if you're upgrading your Arrma 1/14 Typhon, 1/16 Mojave, or 1/18 Granite GROM, this OGRC servo saver set is a solid choice. It's a 25-tooth (25T) micro spline servo horn made from lightweight but strong aluminum alloy, with a stainless steel spring for the saver mechanism. The spring has good elasticity and fatigue resistance, which helps protect your servo from shocks and impacts during those rough landings. The black anodized finish adds wear and corrosion resistance. It's CNC machined for precision, so it should fit your stock servo perfectly. Weighs only 6.5 grams, so it won't add much. Comes as one set (one servo horn). An easy upgrade to improve steering response and durability. Just make sure your servo spline is 25T micro size.
