Deluxe Materials DLMBD38 Liquid Gravity is a tungsten-based liquid ballast system designed for precise center-of-gravity balancing on RC aircraft and models. It can be poured or injected into small cavities, hollow spaces, or purpose-built compartments to add weight exactly where needed without drilling or attaching solid weights. Key Features Tungsten-based liquid ballast for precise CG adjustment Pourable and injectable — fills small cavities and hollow spaces Sets firmly in place once applied Much denser than lead alternatives for minimal space usage Ideal for nose-heavy or tail-heavy CG correction on RC aircraft Compatible with foam, balsa, and composite airframes Specifications Spec Value Part Number DLMBD38 Type Tungsten-based liquid ballast Application CG balancing for RC aircraft and models Weight 12 oz Country of Origin GB
