Cheapest possible "DIY" GPS Waypoint Mini Quad?


Hello, I want to build a 15-20cm quad with GPS waypoint capability and may be obstacle avoidance can be added in the future. But I want to make it as low price as possible. There is an example RTF quad with GPS waypoint function sold for around 100$ which is Hubsan H507A. For this price I couldn't found a DIY solution. Is there any possible diy solution around this price? What do you think? Is it possible?

important to understand the limitations of brushed motors. sure they make quads much cheaper, but you only get a few hours of flight before you start replacing them.
also unless you are only flying in very calm winds (at ground AND aloft), you'll need a more substantial quad to really fly waypoints.

Yes, after some research I decided to use brushless motors. Now the problem is: What is the best frame size and FC that capable waypoint. Is 250mm enough?
