The World Tech Toys Striker Spy Drone was really popular last Christmas and they sold a lot of them. They are a good cheap drone to learn to fly on. You can get replacement parts (some are pricey).
In this video we show the steps involved if you need to replace a motor.
Soldering is required.
For cheap parts; watch Craiglist or eBay for used or broken ones for parts; it's a lot cheaper that way. For example, the motors I have in this video were $16.99 EACH which is robbery. You can get them much cheaper if you order from China but it takes over a month to get them then. I just bought a "returned" one complete on eBay for $17.99 for the ENTIRE drone. Nobody was buying it because it didn't say if it worked. I bought it, and then asked the seller if it worked. They tested it and it works, so it's a brand new one for $17.00.
