This allows you to monitor battery capacity directly on your transmitter screen, optimise run times and receive warnings before battery levels become critically low, preventing unexpected power loss during important races.
- What maintenance does the Blackjack 42 require after use? — After each use, rinse the boat with fresh water to remove salt and debris, dry thoroughly, and check that no water has entered the hull. The water-cooling system should be flushed with fresh water. Periodically check the aluminium components for corrosion, inspect the propeller and strut for damage, and ensure all fasteners remain tight. The moulded composite interior prevents wood rot issues found in older designs.
