19/6/2025 buy another secondhand 1/10 EP truck for Rm150. Saller from kajang cod in KIP mall bangi. This a 2007 RTR 101703 HPI using brushless motor, Am 27Mhz receiver, Monster Truck body.
From my investigation found out this rc with broken lhs front steering hub, missing dogbone, adjustable linkage not tighten. So previous owner repair and left it unattended until parts rusty. Found the dogbone open, use on rear center proppeler shaft. So front run without dogbone. Not a heavy drive, bottom chassis no scratch. This units top review in you tube from europe.
