I want to build a quadcopter, but it is pretty expencive.
Does anyone known where to find a cheap (100-150$) ardupilot mega or mega v2 ( preferably with gps) or a alternative?
Thanks a lot!
Have you tried looking on ebay. When I looked it came up with a number of ardupilots cheaper than 100 dollars but I don't know which one you are after.Not sure if my search results will show for you but look here for starters.
