"For sure the bottom props have to be installed that the letters are on the upper side. You want thrust into the air and not into the ground. When you mount the props upside down, you get a lot less thrust and so the moros have to spin much faster."

"I really like the autotune feature. I first tried it with my tricopter and it worked very well.
When I tried it on my Y6 I had some issues, I described in this thread:
http://www.diydrones.com/forum/topics/y6-with-apm2-5-arducopter-3-1...

I now…"

"No idea?"

"Here is the onboard video."

"I have a feature request for Arduplane. Could it be possible to set the homeposition with a stick combination or a switch or something like that?
Would be great because APM1 with the MTK GPS needs some time to get GPS lock. When I do not want to…"

"A question to cruise mode.
Does ALT_HOLD_FBWCM work in cruise mode?"

"If this works, another idea would be to make a mission with 3 commands.

1. take off to 20m
2. loiter 20 seconds
3. land

On the field I could switch to auto and throw the plane. then, after it reached 20m it begins to loiter. As soon as it loiters,…"

"Today I had a strange issue with my new scratchbuilt tricopter. I wanted to check the ACC Z vibration data and wanted to do some hover just to log data. As it is cold outside, I did it indoor, and I think that safed my copter from flying away.
After…"

"I just finished a Tricopter and tuned Rate PIDs. The copter hovers well, but I am not very happy with the tail. It holds well, but when I yaw and let the stick go, it waggles 2 times.
What PID values should I try< to change? I allready tried…"

"First of all thanks for that great Software.
It's a shame, I cannot test it right now. We have lots of snow and, what is the bigger problem, lots of wind.
So I use the timne to build a new Trikopter for my APM2.5.
When I read the release notes, I…"

"Today noon I was out to test my Y6 with APM2 and 2.9rc5. Could not do that much, because it was very windy and very cold. After half a battery I finished, because could not move my fingers any more.
The short test showed me some issues. First of…"

"Today I tried the rc5 on my Y6 with the APM2. It is really great.
I could not fly a lot around, because I only had the time to go in front of my house and do some hover tests.
Tried Alt Hold and it works very well. Sometimes the copter lost…"

"Today I came up with a little problem, after doing some paramater changing.
The motors of my Y6 did not spin up. When I push throttle up, they did not spin. At full throttle and then puch throttle down, some of the motors did spin up slowly. First I…"

"Hi, is there a way to display the total Amps drawn?
I only can see a panel to display the current Apms, but I want to to see the sum of Amps drawn. I saw some videos of different OSD where this is shown, so I want to ask, if this is also possible…"
