This deal is for the best value smartphone wifi drone with a Sunfounder Raspberry Pi self-driving car kit to teach STEM to kids and adults. The Ruko U11 costs $260 new, has a good battery and camera, and is the best value drone without a gimbal. It's best to start on a drone you don't mind crashing. This one doesn't have any damage. Drones are good to get kids outside. You can extend the range with a USB long range wifi antenna for dirty cheap but you need an Android device with a USB port; I have one for sale for $85.
The Sunfounder Smart Video Car Kit v2.0 kit requires a Raspberry Pi and doesn't come with one, but it comes with four rechargeable batteries for the car and the charger. The car motor controllers are useful beyond the toy project. The kit teaches you the basics of robotics and AI. I know a lot about AI and robotics if you want any help. It will come disassembled with all the pieces.
With the money I get I'm going to get two SpeedyBee Mario 8 frame ($97 on Aliexpress for the frame, $1000 fully kitted out on Amazon). I'm bought two Skyzone Cobra X V4 FPV drone headset ($240 new, $210 on sale now on their website), the Radiomaster GX12 ($170 new) RC transmitter, and I'm getting the Radiomaster Pocket ($80 new) for portability and so we can fly together. The U11 is a lot cheaper in comparison, if you use it a lot you want what I got, but if you don't save your money and buy this for a gift for your family or self.
