Hafiz R., you can use 1.4mm screws with your 'older' version, you can use too, 1.6mm screws for 1102 motors, it works perfectly you must know too that there is a update with new screws holes design, less space than before, but we save compatibility with 0802-1102 3 holes, and 1103 4 holes motors! don't hesitate to join the KAIDJU OWER CLUB (private group on facebook) for more informations, tips, builds infos, KAIDJU community :)
