Worth knowing

Thunder Tiger's first underwater R/C model -- features a dual static/dynamic diving ballast system (internal water pump for hover-in-place static dive, plus elevators/rudder for dynamic dive) with auto-surface safety (low battery, weak signal, or leak detection). Length 774mm, displacement 7700g surface / 7950g submerged. One of the most recognized hobby-grade RC submarines ever produced.
