"I also saw this message when a new flight plan was loaded into APM 2.75, followed by switching from manual to automatic mode. This would suggest a problem with replacing a flight plan or altering steps. The only way I found to clear this…"
"Yes, that is what we use, THR_SUPP_MAN = 0. This requires a little history to explain. At first, APM autotakeoff did not suppress the throttle and the prop would spin as soon as you went to AUTO mode. This is considered by many to…"
I guess I was not clear enough. AutoTakeoff worked as expected only when the RC transmitter throttle was advanced. The APM detected acceleration, unsuppressed the channel and set the channel output to the configured maximum, which…"
We made several tests this morning with our EZ Star "testbed" plane. This uses the same (APM 2.75) firmware but does not have the size risk of the X-8.
Prior to starting, I ensured that we were using the same parameters you…"
I am going to try this parameter set tomorrow morning and will report how it performs. But, I do have one question ....
Setting THR_SUPP_MAN to 1 is for setting ground idle with glow motors. If you did set this to 1 and then…"
"I have been trying this with a X8 and something appears to have changed in the recent firmware. AutoTakeoff was working earlier this year, arounf the March timeframe. It stopped working reliably when the firmware was updated to ArduPlane…"
"This doc page in the "new" wiki still describes the old firmware. The current APM version "requires" a manual level before any flight. There is no option for auto leveling as in earlier firmwares. The level…"
"I've found the best airframe performance (trim and efficiency) to be slightly nose high, about 3 or 4 degrees AoA. I just put the x8 on a level surface and put the lid under the nose to lift it about 1 inch, that gives a few degrees nose up and…"
"As I understand it, the new levelling procedure uses 6 reference points to find level (of the APM) hence the 'level dance' we're all doing now. You can do it with the APM outside the plane or copter as it's APM specific rather…"
As of the more recent versions of ArduPlane, the firmware no longer does an automatic level on startup. Instead, that has become one of the initial startup steps when installing it in a new plane.In the past, I have glued a bubble sight onto the rear spar enclosure and used that as "level". Recently, someone else said they use the inside floor near the CG line. Both seem ok, but both are different. I just looked at the wing and the underside is angled slightly node-down with my bubble level…See More
"Removing the Mission Planner's manual leveling ability was not an oversight, it appears to have been directed by "Tridge" from the developers group. Here's his email to Michael Osborne telling him to disable that ability in…"
"This is a pretty big change to how APM has worked historically. I believe the change was made to prevent problems with an airborne restart, but this is now a "required" step in all setups.
I saw the problem two days ago with a…"
"Hi, I am also having this problem. I have a new, unflown APM2.5 and just loaded 2.74b firmware. The box is sitting level on my bench but starts up reporting node up of 0.2 units and left roll of 2.2 units. I've tried a reset…"
