Parker Stephen replied to Parker Stephen's discussion Please Help! APM Hex crash in RTL. Need to fix by tomorrow.
"Chris, I'm sure you're a busy guy but I really could use some help here.  This problem surfaced again while in stabilize mode and I'm at a loss.  Wrecked my videography copter two times over the last two days and now my gimbal is broken and I can't…"

"With ATC_RATE_RP_MAX set to 9000 centidegrees/s, the problem seems to have subsided.  I also havled the ATC_ACCEL_RP_MAX to half of the default value.  The copter seems to move around a little in the wind, but it RTL's properly now with no crashing."

"I think I've found the source of the problem, or possibly sources.  My board mount has some slop in it which was obviously causing overcorrection.  I plan to use this information found in a post from Leonard Hall to attempt to fix the problem.
We…"

Parker Stephen replied to Brian Veenker's discussion Violent over-correction on mode change?
"It's Arducopter.  I haven't tried to change anything, but I'm really afraid to use RTL now or go near the end of my radio range and hit the failsafe."

"It's the latest version, I just updated it a few days ago.  This has been an ongoing problem with the hex.  It is quite overpowered, which may contribute. Let me know if logs are needed.
EDIT:  It's the latest stable version BTW, not beta."

"I just had this cause a wreck on my hexacopter.  It really is quite annoying.  I'm not sure what parameter needs to be changed though.  Wish I could help more."

I finally thought I had my copter all tuned up and working well, but today I had a wreck that cost me a motor mount and prop.  I engaged RTL a few feet off the ground and the copter immediately pitched hard into the wind, overshooting apparently,…

Parker Stephen replied to Parker Stephen's discussion Having loiter problems on Flamewheel 450 clone with APM
"Solved this.  Compass orientation was wrong, I changed it to yaw 180 and loiter is working fine."

Parker Stephen replied to zheng jishi's discussion What is the problem with my copter?
"As far as I know, there is no failsafe for low board voltage. If the board doesn't have proper voltage, it will be unable to navigate the craft since it doesn't have enough voltage to stay powered on. I would get a 5v BEC for power to the board. It…"

Parker Stephen replied to Roger Nordin's discussion Crash after rudder input during RTL operation
"I know the source of your problem, I've seen this before on one of my copters.  The barometer is very sensitive to light.  When you yawed, it's likely that sunlight came through just right and hit the barometer, causing the reading to spike.  This…"

Parker Stephen replied to zheng jishi's discussion What is the problem with my copter?
"It looks like your board supply voltage drops as low as 4.55v at some points.  It's likely that your board is browning out.  The voltage tolerance for the board is 5 +/- 0.25v so anything below 4.75 is not good."

I am having some problems getting loiter working well on my quad.  I used to have this same problem, then took parts off of the quad for another project.  Just got it up and running again and still the same problem.As soon as I hit loiter, the…

I have been using my T2D gimbal and it works great, but I run in to a problem when I try to download the footage.  The Tarot USB plug that goes with the gimbal makes it so that I can't remove the SD card from the camera.  It's not too hard to take…

I just want to take this opportunity to notify everybody here that is looking for a GoPro lens solution that you don't have to pay $400+ to get a good quality lens.  I've found a supplier (with whom I have no relations) that provides similar lenses…

Parker Stephen replied to Mihai's discussion LOITER and RTL crashing bug
"Could you please explain how to apply the patch or modify the code directly?  I would like to get this applied before I get my copter back up in the air with the gimbal and camera!  Also thanks for your contributions to the code, we non-code-savvy…"
