VEXpro VersaPlanetary 180° Drive Kits - VEXpro 217-6011, For all of its strengths, the VersaPlanetary gearbox from the VEXpro range can sometimes be too long to fit into tight spaces, especially once you account for the input motor.In such tight applications, the VersaPlanetary 180° drive kit is the perfect solution. By \"folding\" the motor back on your VersaPlanetary gearbox, you can cut the length of your VersaPlanetary-plus-motor assembly in half.For an easy, off the shelf solution, use the gusset kit and its associated GT2 belts and pulleys. Or, you can use the standalone 180° drive block to integrate into custom designs. VEXpro 217-6011 VersaPlanetary 180 Deg. Drive Kit
