"I also was not able to get a GPS lock unless it was plugged into the UBS. I had my gps line ziptied next to my servo wires. I cut the ziptie and gave the gps line a little room and it solved my issue."

"Personally, I think Loiter has improved, but I am getting random cut outs.  In other words, I will be in loiter behaving fine, then it will start to drift (lose GPS).  It didn't seem to do this with V2.8.1+ older GPS FW (whatever came…"

"It's counter-intuitive to me as well, but there is plenty of evidence suggesting that ND filters help with jello.  I myself have seen it as well.  Heck, just fly at noon and then at dusk with a Gopro and you will see the difference"

First flights with APM 2.0, and 3DR frame

Posted on December 28, 2011 at 5:54pm 10 Comments

Finally got the time to finish my quad and (attempt to) fly it!  It's my first quad. and I went a little different with the setup (see specs below) to try and see if I could push the propulsive efficiency up a bit and have more power on tap for heavier payloads down the line.   My static tests indicated that this is the case, but we'll see if it was worth the effort after some more flying :)

 

Setup:

APM 2.0

3DR Frame

DT750kv motors
