Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will these wires work with older MR-03 variants?

The MZ503-1B is designed for MR-03VE geometry. Some older MR-03 versions use different connectors or layouts, so check physical fit and connector type before assuming compatibility.

Do I need special tools to fit the wires?

Basic tools like small pliers, a soldering iron if soldered joints are used, and trim cutters are usually enough. The set is designed for simple replacement with common hobby tools.

How should I check the connections after fitting?

After installation, confirm secure connectors and do a low-speed bench test to verify motor spin and ESC response before a full run. Inspect for loose wires or pinching.
