HoBao have released 3 new molded foam inserts for off-road racers. Available in 3 different compounds the black (firm) insert is ideal for maximising control as the extra firmness allows the tyre to maintain its shape. This in turn means the tyre has increased traction and maneuverability. The grey (medium) compound is better suited for tracks which include jumps. There is more ‘give’ in the insert allowing it to soak up more of the impact when landing. For the best of both worlds you can always go for the more professional dual compound. While more expensive than the other single colour inserts, the dual insert has hardened shoulders with a softer strip in the middle. This means you get the added traction of the black insert with the improved dampening of the grey insert.
