tank with water balls cannon

1:12 scale 4WD tank with cannon that shoots water balls. The tank has beads on the wheels that enable driving it sideways in addition to forward and reverse and turning. The cannon elevation can be adjusted from the remote. This is a similar tank to the DJI S1 that sells for $400-500. Rechargeable batteries give it 20 minutes of play time and the 2.4 GHz remote allows to run up to 50 of these at the same time with no interference. Buy the mobile target and you get to count how many hits you got.
