The quadcopter project was (is?) my second attempt at building a flying machine. This one was build with stability and roughness in mind from the outset and was designed to be a FPV platform.
I was able to get this one very stable and took it for a quite a few test flights.
In the end I was defeated by a lack of good flying days, paranoia about where I could safely learn to fly such a dangerous device and my own lack of time to become a decent pilot.
I expect one day to revive it as a project assuming “drones” aren’t banned in the mean time.
