XAircraft Xaircraft, AVRoto motors, Vibration - (Spit, Grit, and a whole lot of duck tape)

Before I start I can say this may not be the best combination but for those of you that go this root its doable - but not strongly suggested - there are other ways to do this, probably - Will leave it at that.

It taken me forever but between the beefy motors I put on (avroto) WK-M, frame modification, and maytack ESC. I finally have can say my copter is working not too bad.

The AVROTO motors do not sit well on existing parts, the carbon fiber disk on the motor mounts, the screws used to hold them down will end up hitting the motors, so what I did to get around it was just add on mounting disk on top of the existing ones. I had to bore out the holes to allow the head of the disk anchor screws to not touch, then the second disk sitting on top would sit flat, This will keep the screws from hitting the motors.

Once I got past that part I then learned that although the motors worked great, that because of there size, the vibration they threw off were just to much for the plastic motor mount endings, causing the vibration to resignate through out the frame right into the camera mount, i.e causing it to show up in the video, not good either. From here it took me about 2 and half month to figure out a way around it. I would spend each night taking apart the mount build something with cushions, foam, springs, etc.... and many combinations.

It was not until I decided to make a bridge between the gear where I could sit a platform with my camera mount on it, that was when started to have good progress. That along with a support bracing each arm helping with the vibration. What I found was the movement of the mount made sense and I saw the results immediately. Centering the weight made a huge difference how my quad flew. There were some other things I did but for my purpose here is a result seen in my video.

this footage straight from the camera, true raw vid with no editing, or de-shaking going on, even on the youtube side.



I am not sure if this will help anyone but maybe it or at lease give you an idea how to get to a point where you have a better copter. At the end of the day I have something that works, it may not be the most crafty craft, more like a heavy beast 3000g with a 4s 6600mAh batter, I may not be getting the top flight time but I am good for 11 mins. For now I am good with that until I make my move from there to a bigger and better situation.

take care all Jack

here is a link, that will give you a good idea, I have done some changes since to make it better but, I am generally in this realm over the next few days in between me going out of town I will try to get better photos and post them up here.


The camera is a sony cybershot hx9v

I put the Avroto motors on the Xaircraft DIY Hexa. I had to use a Dremel to make the carbon fiber motor mount discs a little wider. It was just enough to ensure that the retaining pin would not touch the disk itself. My craft flies great. No visible vibration in video. It sounds like a finely tuned machine in the air. I've been thinking about building an Xaircraft X650 with stronger motors. I'll have to do some more research.... Thanks!

Dewster, I am curious what size props are you using on your hexa build. I am thinking of purchasing a DJI 550 and try it our with my AVROTO motors but I am not sure where to start with the props.

Thanks for your input about your build.
