Volantex RC Vector 30 motorboat with self-reversing system up to 50km/h 795-8B RTR - brushed motor 

Description :
The 30cm Volantex RC Vector 30 motorboat delivers excellent performance. Thanks to its well-designed structure with water ribs and trim tabs, this little boat stays stable in a pool, lake, or even river. Thanks to the water-cooling system, you don't have to worry about the motor or ESC overheating, even when the boat reaches a top speed of 50+ km/h.
The Vector 30 motorboat is fully operational and includes a 2-channel radio using 2.4 GHz technology. It's also been upgraded with a reverse function, meaning that whenever you're having trouble with a blockage, simply reverse it back to the track and you'll be back on track!
