Polaroid Cube Plus is simple to attach to the Syma Quad-copter with tape or Velcro. I recommend buying a extra battery because you get about 5 minutes of fly time per full charge. Currently I will be upgrading but for 3 years this very cheap hack allowed me to get great shots all for under 200 USD. You can get a waterproof housing for great underwater shots.
To perform this hack all you need is tape and to position the Cube under the battery pack aligned so the Drone will fly accurately. The only downside with this model of camera is you don’t get to see what you are capturing in real time. They have a new version with wifi that you can view live feed using a phone/computer. I was able to fly in snow, wind with ease using this Polaroid/Drone. I give this combo 5 out of 5 stars because of the low cost and multi use of the Polaroid cube.
