The Exotek 22S Drag Slotted Lightweight Motor Plate is 100% CNC machined and vented with aggressive slot cuts to reduce weight and help lower the motor temps. The slots also help cool down the inner slipper parts by letting cooler air pass through. The extra machining brings the weight down to 14 grams (6 grams lighter than stock), but the critical motor mounting areas are still intact to minimize flex for solid motor mounting and gear mesh.
