Using this TBS Ethix Propeller Organizer is easy. First, identify the type of prop you have. If it's a clockwise prop, put it in the green bag. Counter - clockwise props go in the clear bag, and any bends or chipped 'broken' props should be placed in the smoked - grey bag. When you need a prop, just unzip the corresponding bag. As for maintenance, keep the bags clean by wiping them with a soft, dry cloth. Make sure to zip the bags properly after use to prevent props from falling out. Also, avoid exposing the organizer to extreme heat or sharp objects to prevent damage to the bags.
