Mini RC submarine review: The new 777 sub version made by Happy cow. (also sold by Carson)

The very popular and very cheap triple 7 radio remote controlled submarine, by Happy cow, got an update. So got it better or worse? Find out in this in depth test of this “RTR 6 CH (channel) three propellor” micro RC sub.

In this review I’ll discuss battery life, transmitter range and more.
Maximum depth is 0.8 m acoording to the manual. (In reality 0.5m. (20″))
WARNING! this 777 RC model , also called “torpedo pigboat, is not waterproof at depths over 50 cm (20”) although it has silicone rings to keep the water out. If your boat behaves odd when still in range or sinks, quickly get it out of the swimming pool or pond and leave it to dry. Even better is to remove the small screws so that you can remove the top and bottom part. After that you can give the nose of the submarine a twist and carefully take it off so that water can get out. Be careful not to break the wires!
