Hi there, quick question. I'm flying my hexa on the latest arducopter code and an APM 2.5. The default PIDs work fine for most everything, it can even navigate waypoints with ease. However, I have…Continue

ModeratorMorli commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock.
"Most of the motor shaft are not notched for the prop grub screws to bite , grinding/cutting a small notch without debalancing the motor is all the is required for fixing the prop, never thought that some might thread lock the prop to the shaft…"
Harry commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."This is good information all around. I had the same failure on my tricopter today. I'm hovering about 6 inches up, trying to see which way it wants to go first and then Bam, left motor comes off and twists up into a knot and breaks…"
Stephen Gienow commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."Oliver, I know this very well! Some members of my lab took three of our Mikrokopter Hexas (retrofitted with APM2.5's of course) to costa rica for some photo collections. Unfortunately for them, one of them decided to threadlock all…"
Oliver commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."It was mentioned (once) above, correctly, that all metal-to-metal threads should be threadlocked. But not mentioned is that non-metallic joints should NOT be threadlocked. The threadlock compond may attack and degrade a non-metallic material,…"

"Oh, and I should point out, try not to get the shaft to hot. If it turns blue, you're doing it wrong and could cause problems. Take it easy with the dremel. Let the cutter do the work and don't push it. Maybe take a…"
DeveloperR_Lefebvre commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock.
"Yup, I have a lathe and other tools, but I used a Dremel anyway. I recommend taking some paper, push the shaft through the paper making a small hole, wrap the paper around the motor. Cut the shaft, then careful take the motor out of the…"

Scott Berfield commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."Should have read "Dremel" - darned autocorrect."
Scott Berfield commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."I use a dreamed rotary tool with a cutoff wheel followed up with a fine tooth file."
Stephen Gienow commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."Thanks for the advice, I dislike how high the collets sit on the shaft. However I don't have the tools to safely trim those shafts. How did you trim yours?"
John Maffetone commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."From the photos it looks like the props are sitting way to high on the motor shafts which would cause vibration even with perfectly balanced props and motors. The prop shafts need to be trimmed so that the prop collet is pretty touching the motor. I…"
DeveloperR_Lefebvre commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock.
"Now, if you want the ultimate in reliability, you use safety wire. That would be fun!
Using set screws to hold shafts, even with threadlock, is also a horrible thing to do. It's cheap and easy, but again, is not a "best…"

I'd like to preface this post with this statement: I love my (lab's) Udrones Hexa C, but I feel that this simple fix would save a lot of grief for Udrones flyers.
So! I have noticed that the Udrones Hexa C that I use has a nasty habit of vibrating its motor mounting screws loose.…
