Questions & Answers

Real questions from real customers. Why not ask your own?

Do you know if this would fit the Traxxas Titan 12T 550 Brushed Motor with both of them then paired together inside the chassis of a HPI Wheely King 4x4? Or would the Chassis space in the wheely King 4x4 not be sufficient?
