"So I realize I'm reviving and old dead thread, but after much searching I couldn't find an answer to this problem that suited me. I understand the need for headroom for stabilization, but in my case there was way too much being reserved,…"

"You should see the ceiling in my livingroom.. :)  "

"Maybe the old props was upside down? You would still be able to fly with props the wrong way, but the efficiency is much lower.  "

"So I never figured out a parameter that helps increase thrust. Maybe there isn't one. But I did figure out my problem. I had at least one weak propeller. I switched out a couple of the regular 10X45 propellers and all of a sudden I am taking…"

"I think this is only used internally. When flying the controller saves the value needed to hover into the TRIM_THROTTLE. I don't think it makes any difference changing this."

"I have a similar problem... The only way to get mine to fly right is use 10" props...  The yaw works perfectly.. But it has no power barely lifts off... Then I put 12” props and but then any yaw input it becomes very…"

"Kristian, did you ever find out what the TRIM_THROTTLE is for? I am having lift issues on my new copter also. I have a standard 3DR frame with the 850 kV motors and 3S Lipos and it gets to a point (at full throttle) where it just barely wants to…"

"Ok? I don't get it. I own a webshop where my customers use Paypal every day. I also use Paypal as a buyer several times a week. It's a win-win situation. Never had any trouble."

"Sooo..  Paypal is a bad thing..?  "

"I have some other quadcopters with 5V lines from all the ESC's connected. Never had any problem with these. A diode may be a good idea, but this will bring the voltage down a little? I have gps/mag. No sonar. The continues tone from…"

"I grounded all ESC's to the APM, and connected two of the ESC's +5V lines to the APM. The reason why I connect two +5V lines form ESC's to APM is to have some redundancy and more available current. I know this means…"

"I run 2.0.49 and I can adjust height in alt.hold mode using throttle stick. The only problem is that I have to give 100% throttle to activate this, and it's very violent behaviour. There is no in between, just full power upwards."

"It's not possible to store the values. When I reboot the settings are gone. Compiling and uploading with arduino, followed by erase and reset through the cli and APM planner did not fix the issue. But hten I tried uploading new firmware…"

"I loaded 2.0.49 and reset everything. The 4 blank sections are still blank. Why? I haven't saved these values, so I have a problem finding values that kind of works. Anyone got some values for me that I can start of with?  "

"Ok. i will install another BEC to make sure everything gets its power. I discovered that Altitude hold pid's etc was gone, probably after this event. Does this mean anything? "

"The memory is filled with -1 and overwritten as you go. It seems to have stopped in mid write. Jason"
