RetroArms PandoRA, fully CNC machined gears from high quality hardened steel. The most durable gears ever made? The PandoRA gears are machined from one solid block of steel, so there are no more separate layers in the gears! RetroArms – CNC Engineering at Best RetroArms is a Czech airsoft company which manufactures high-quality upgrade and spare parts. The company has become known from its CNC machined parts, especially its super durable gearboxes which are made from 7075 aluminum. RetroArms gives its gearboxes a lifelong guarantee against breaking which tells us a lot about the quality of the parts! Shimming, what is it? Shimming refers to adjusting the angle of the motor gear and the gearbox gears. It is always good to shim the gears when you change the gears or the bearings, or you install them into a new gearbox shell. In order to adjust the angle of the gears you need shims. You’ll find illustrated instructions for shimming in Tradetech!
