??The UDI003 is a wireless racing boat that is fast£¬ fun and easy to use. Its stylish design is nice to look at and it really performs for a boat of this size. This model includes a 180 magnetic motor drive system Lithium-ion battery£¬ for speeds of up to 20KM/H. The boat and transmitter take advantage of advanced 2.4GHz automatic code pairing technology to control the boat over long distances. What is more£¬ if the boat capsizes in the water£¬ push the throttle trigger forward and then quickly pull backward. The boat will automatically right itself. Being completely ready to run£¬ it is great for both beginners and experienced boaters alike. The motor£¬ ESC and steering servo are all pre-installed. It is a great little boat at a great price.

Features:
Special anti-tilt function prevents tilting and keeps the boat sailing.
Capsize recovery function.
Water-cooled motor extends the life of the boat.
Built-in left and right navigation rudders enhancing sailing stability.
Low-voltage alarm function: when the battery runs low£¬ the transmitter will sound "Di£¬di£¬di". This warns that you have about 1 minute left£¬ so you can sail it back for retrieval.
Transmitter detects when 2.4G signal becomes weak and flashes an out-of-range light.
