Chase Friedman replied to Drone Guy's discussion Failsafe with Turnigy 9x transmitter/receiver
"Heyo! 
I'll warn you that probably 90% of the people on this forum are hobbyists and don't have a lot of working knowledge about how the APM works myself included. From the discussions I've been in on most of the people are brainstorming on how to…"

Chase Friedman replied to Chase Friedman's discussion Discharge Warning?
"Thanks Mike and Ioan. I appreciate the tips.

Mike what brand would you reccomend? I wanting to achieve about an hour worth of flight time with a medium size load. Is that even possible with a hexacopter? I found some 6000 mah 14.8v on amazon but…"

Chase Friedman replied to James Small's discussion Neo-6m reported positon jumps large distances during automated flight
"I'm definitely not a pro but I know throwing suggestions out can definitely help. So here are a couple I could think of:

Have you tried increasing the amount of satellites connected to the gps before arming? 
Is the current to the gps constant? Use…"

Chase Friedman replied to Ned Horning's discussion Need help figuring out why my quad keeps flipping
"Ned,

You're situation sounds extremely similar to mine. I would get it up in the air, I could loiter, circle, stabilize. About 3-4 minutes in the flight it would go haywire and flip, or a motor would stop just enough to make it dive to try to…"

Chase Friedman replied to Billy Smith's discussion Stability tuning
"Billy,

I've had a similar experience. I've also found that jumping from 4.5 to 4.2 is a huge jump for my hexacopter as the props get bigger. Follow this guide in the link below and more specifically watch the video halfway down the page. If you…"

Hey guys!So I think I've busted two of my batteries by discharging them too much while flying. I would typically fly the battery until I notice that I have to increase the throttle closer to full throttle. I've got 3 zippy 2650mah 14.8v batteries…

"Make sure you erase and reset your APM and then upgrade to 2.9.1b. Problems seem to follow the upgrades. "

Chase Friedman replied to Euan Ramsay's discussion Various alt loss scenarios on alt hold, auto and loiter
"Euan, 

When you upgraded to 3.0 did you erase and reset your apm? We've been discussing some of the issues with upgrading that are causing some wacky problems. "

Chase Friedman replied to Keith Callaghan's discussion Big Crash today - what happened
"Reading this story makes me wonder if it is possible to code a failsafe (for hexacopters) that realizes one of the motors is out. It then compensates just enough to make a quick rough landing? 

Maybe cut throttle to the opposite motor and try to…"

Chase Friedman replied to Dustin's discussion 20 great flights, then chaos....
"Dustin, 

If you upgraded the firmware on the apm you might want to erase everything and reload the most current firmware. It seems that when you upgrade from one version to the next some variables don't get erased or rewritten which has led to 99%…"

I'd attach this to the post I made a couple of days ago but I think this could possibly get rid of any errors you're seeing. I haven't seen these any where in the manual but I highly reccomend (if your having major trouble) that you erase and reset…

Chase Friedman replied to Chase Friedman's discussion No roll or pitch controls
"After a little more time I believe the error is in the Advanced parameters but I can't find which variable it is. "

Chase Friedman replied to Chase Friedman's discussion No roll or pitch controls
"I've verified that it isn't the radio by changing the flight mode from heli to acro as well. For some reason the APM board isn't sending commands to roll or pitch. "

Hello! Still in the process of calibrating my hexa! I've got the APM2.5 load with the v3rc1 hex file. I can calibrate my turnigy 9x radio in the software and see the all controls move like they should. Roll and Pitch move in line with the…
