Quite honestly, I've never flown a quad before.. So why not do the first flight at night?.. Sounds like the sensible thing to do, right? (Insert sarcasm here). But seriously, .. Got the I1 yesterday, I installed the new FW as per cswamp1's video link. All went well there. Calibrated, imu, compass, checked everything, and I let her idle for a couple of minutes a few feet off the ground. First impression: this thing is rock solid!!!...and if you've never had the pleasure of flying at night... Go do it now! Looked like aliens were about to take over!, it was cool! Handling right out of the box, I was more than impressed. Very predictable. Very stable. Can't wait to do a day flight and get to work on some videos.
