Holy Stone HS170 Predator Mini RC Helicopter Drone

 This drone has a surprisingly good quality given the price. It has 3 different modes for beginners to advanced modes and it is really fun to fly. Includes a set of spare blades in case you lose or break one with an intense flight.

Each of the blades has a different angle, so make sure the replacement is installed correctly, otherwise the drone will not fly properly and may even tip over. This drone has flexible landing feet to provide some cushioning when the quadcopter lands accidentally or accidentally.

The feet are elastic, so do not be surprised to land when the drone turns. It also has curved propeller protectors to mitigate the impact on the wall and on the roof. These features increase the robustness of this little drone.

Brand: Holy Stone
Model: HS170
Weight: 13.6 ounces
Rating: 4.4 out of 5 stars

  • Battery and flight time
    This drone comes with a replaceable battery that makes recharging easier. Over time, the battery will be depleted, but you can order a new one. Just look in the manual for the part number.
    There’s a cable that connects the battery to the drone that hangs on the side and looks a bit strange, but that does not affect the drone flight’s performance.
    It takes about 30 minutes to recharge the battery, and you get about 8 minutes of actual flight time. We recommend that you buy extra batteries so you do not have to wait to recharge the battery before your next flight.
  • Controller
    The controller is a bit awkward and carries 6 A batteries, which are not included. The drone control has a typical up-and-down accelerator and left and right steering levers that actually rotate the quadrocopter. It also has controls for a tilt to the left and to the right.
    There is also a Headless Mode option, which can be activated by pressing and holding the button. However, there is an annoying beep to remind you that headless mode is active.

  • Flight performance
    There are three-speed settings that also affect the yaw rate with each level. In the low setting, the drone has a slow response, but this is perfect for beginners. The fun is in the middle and high-frequency settings. Yawing is still a bit slow, but the tipping rate more than compensates for this.
