This Micro Long Can 8.5mm x 23mm Coreless Motor is a popular power upgrade to many ultra-micro models that used the PKZ3624 system. The motor ships pre-soldered with an 8cm long wire lead-out, standard 2 pin 1.27mm pin space plug and 9 tooth brass pinion. This product is directly compatible with both our wide and narrow mount 4:1 ratio gearboxes.
