About Me:
I love drones and electronics in general. I'm also a software engineer, so I bring a software background to this field. I love it!
Please tell us a bit about your UAV interest
I fly drones just for fun in my free time. I would love to have a bigger community around me of people who do it too.

"I think that's very possible. After doing lots more testing and adjusting, it turns out that the PID loops were way out of whack, so I got MUCH better results after adjusting those. I also think the copter was out of balance, but unfortunately I…"
Hello DIY Drones community,I'm seeking some assistance trying to figure out the source of wobbliness on my Hexacopter. I've attached the log here. What happens is the drone will take off and it seems relatively stable. I can generally make gentle…
"Ok it's update time. The first thing I did was balance the props. This didn't make any difference. Same swirly behavior followed by a crash.
Then, I made a setup to strap down the hex and rev up the motors without taking off. This was key in…"

"So it looks to me like the vibrations are insanely high, but I'm not very good at reading logs. Can someone confirm this for me? That would be strange since the Pixhawk is mounted on vibration-dampening gel, so I'm not sure why it would be that…"
I am DESPERATELY trying to figure out why my hexacopter won't fly level in stabilize mode (not altitude hold, just regular stabilize). Please please please help! I'm using a Pixhawk. The hex flew fine on an old frame, then, I moved to a new frame…
"Ok, that's critical information that I shouldn't rely on VIBE for vibration monitoring then. What is the best way to examine vibrations in that case?"
"Hey, sorry for the delay in response. I was out of town previously and just had a chance today to mess with this. I've attached my exported param file. I tried setting all the parameters above like you said. There seems to be less yaw drift…"
"Interesting. I read somewhere else that one way to address the efficiency issues on coaxial props is to use a smaller higher pitch prop on the bottom. Why do you think it would be better the other way? And why do you suggest 11.47 for both top…"
"Am I crazy, or is there no way to export a .param file from a .bin file using APM planner (I'm on a mac, so don't have Mission Planner right now). Here is a link to the .bin log.…"
"Right. I was referring to the fact that motors are so close together, and that there's 8 of them, which is a lot of power. I'm wondering if I wouldn't see these issues if I got larger arms, like you do, and spread the motors apart. Thoughts?"
"So I wanted to see if perhaps the copter is way too powerful for it's own good, so I found a big LiPo lying around strapped it on just for added weight. I didn't even do a good job centering it. It now hovers around 40% throttle. The heavy…"
"Actually I just learned about the VIBE set of values in the logs. According to those I think my x and y vibrations are OK, but the z one is a little high. I've seen a copter suffer from high vibrations before and this definitely wasn't exhibiting…"
"Interesting. The Pixhawk is on a layer of vibration dampening foam. I'm going to do some propeller balancing and see if it gets better. Can you tell me which log values you examined to find the vibrations?"
Hey guys,I know I'm not the first person to complain of this, but I've been scouring the forums trying to find answer, and none have pointed to a solution that worked for me. I have a beefy octocopter in an X8 configuration using a Pixhawk and APM…
"Oh shoot. I thought I had enabled full logging. I'll have to double check that. But that doesn't explain why I couldn't take control again, does it? After switching back into stabilize mode, shouldn't I still be able to guide it manually?…"
I need help trying to figure out why my hexacopter running APM copter (version 3.2, I think, but I'm not sure how to check) suddenly had a mind of its own. Here's what happened - you can see it all in the logs I've attached: I took the drone off…
