On flat surfaces B-Unstoppable achieves outstanding performance in driving across difficult terrain. It can turn on the spot, which is extremely useful in limited space, or it can provide 360 view for on-board camera. When the obstacles become too big, it can simply take-off and fly over them. Hybrid weighs only 84 g, therefore it can operate nearly everywhere, without worry of falling down and causing damages.
Despite small size and low cost, B-unstoppable has good endurance: 9 min of flying, 10-18 driving, combined endurance 12-15 min. It has powerful coreless DC motors, 900 mAh Li-po battery. It comes with 2.4 GHz radio transmitter. Front and back lights, that allows for night flying as well as indicating a low battery level.
B-unstoppable is a cool toy/drone for everyone, that can be used indoor or outdoor. It is extremely easy to control; flicking a mode button will convert tank to quadcopter. Steering is also very simple, in the air B-unstoppable is controlled as any other quadcopter. On the ground each track is controlled by separate channel so you get the full experience of driving a tank.
Once B-unstoppable drives over the obstacle, the lower part of caterpillar track adjusts according to terrain.
Tread tension is maintained by arms at either end, which flex in and out by up to 4 mm as the B-unstoppable goes over obstacles.
The arm and canopy design is focused on providing the most efficient shape to reduce drag: the main body (canopy) does not shadow the propeller, therefore does not take away the static thrust. Also, the arms of B-unstoppable are streamlined which further reduces the drag. Simply the best drone to buy.
