I've had to do a small rebuild after a crash on my 3dr arducopter - nothing major - cracked arm at the motor mount. As soon as the weather breaks a little I want to get it in the air again and was going to upgrade to 3.1. I figure I should run AutoTune again and was wondering how much room I need. I have about 30 feet in the backyard and that was plenty to do the old autotune where you just fly it but not sure about this new autotune process. Any thoughts is as to whether or not this is enough room or do I need lots more?
More room is always better when experimenting. You might also get multipathing issues in a back yard. So the more potential for issues your remove the better.
