I converted a Doyusha 1/14 toy radio control car into a hobby RC car. Here's a reference video of a previous build: "1/14 Doyusha Lamborghini Countach LP500S Radio Control Lamborghini Wolf Countach" This time, I used an old, slightly damaged, transmitter: KO PROPO (Kondo Kagaku) Transmitter: EX-1 PRECIOUS FM40MHz Receiver: KR-294F The LEDs are installed but not wired, so they don't light up. I used a used toy RC car with little wear. The body has fine scratches. The parts for adding the servo are original, designed and manufactured by me. They were created using a layered 3D printer. Operation has been confirmed, but as this is a modified item, no warranty is provided. Please prepare your own AA batteries. Thank you.
