I’d like to share with you the RC mod of the 42077 Buggy B model with building instructions.
Where you see “Original steps x-y” please follow the original instructions. Some custom steps are generic, but some of them are alternatives. Please choose one of them to build, e.g. “AAA battery box / rechargeable battery box” or “AA battery box”.
The RC mod uses mostly parts from the original 42077 set. There are a few extra parts needed (gears) for each motor variation, the list is available on each instruction page and the full part list is available on rebrickable.com
Instructions for the Power Functions 2 L motor mod
– driven by 2 Power Functions L motors
– steering by Power Functions Servo motor
– Battery options – AAA/rechargeable/AA battery box
