Hello,
I installed an Attopilot 90amps sensor for current and voltage on my Octo.
I then did the mission planner configuration in battery monitor, first trying with the preprogrammed Attopilot 90 option in the sensors drop down list. The calced voltage

I plan to wire my X8 octo so:
As I must use the attopilot sensor (because I exceed the 3DR power module capacity of 90 amps), I am worried that connecting the ground wire of the attopilot module to the APM will create a ground loop with the existin

I've to power APM with 6S batteries. I intend to use the PDB as power source. I must therefore step the voltage down to APM's required level, that is between 4.8V and 5.25V. This range must be kept under load to avoid a brown out.
This is where the

In continuation of selecting the best motor for my X8 (Octo coaxial) build for video/photography (see post here : http://www.diydrones.com/group/arducopterusergroup/forum/topics/tiger-motors-propellers-combinations-for-an-heavy-lift-octocopter)

I have a question about powering the APM based on a UBEC (not via 3DR power module):
-JP1 is now off
-Can I then plug a UBEC 5,3V directly on the APM A0-A11 side rail ?
Or do I have to plug on the servo outputs and put JP1 back on ? I try not to

I have been doing quite a bit of analysis for what would be the best tiger motor model/propeller combination for improving my heavy lift octocopter.
I am sharing here an excel analysis sheet I made for that, as it may be useful to share this

I have ordered a replacement 20 ESC to replace a stock 3DR 20 amp (old ones, not SimonK).
Although I ordered online explicitly a 20 Amp 3DR ESC, I received instead a jDrones AC20-2.0 which says on the jdrones web site is running "UltraPWM softw

I have both a mission planner incoherent behaviour warning and a recommandation for others to avoid what happened to me using Mission planner's flight planning tool.
As can be seen in the attached picture, I made a simple mission starting with a take
Read more…I programmed the following mission:
It is a quad, 3DR frame, nothing fancy, APM running V3.0.1.
It executed the auto mission until waypoint 3 then I saw the quad go down in an apparent controlled manner (it is not like i lost a prop) still moving towar

For a long time I noticed an issue in mission planner related to the wrong battery voltage measurement and display and also the issue to enter a value with a decimal in the low_volt parameter:
Here is a picture of the display in mission planner
Read more…I finally did the test of hard fixing the APM case to the frame, thus not having two separate masses with vibration dampening materials in between, as before (i.e. : frame/props on one side and APM on the other side).
This is explain by Forrest Frantz

Like many of you and following the general consensus, I use moongel to isolate APM from my frame's vibrations. I have got quite good results and was at worst in a vibration range of plus or minus 0,2g (between 8 and 12 on the mission planner graph

I noticed in my last video filming some low frequency right/left (yaw) movements. I looked at my Tlog and noticed indeed that I have a small yaw drift although I do not touch the yaw stick.
How can this be explained ? What could be the causes ?

I finished my last heavy setup for picture/video filming. It is a X8 quad, based on a VulcanFrame, embarking a brushless gimbal and a NEX5, two lipo 4500mah batteries, 20A ESCs, 8 Tigermotors MN3110-700KV, 4 APC props on top 11x4,7 and 4 APC pr

I just finished my conversion from quad to OCTO quad. I installed 10" 4,7 props on top and 11" 4,7 props on bottom. I get a hover at full lbattery at 55% throttle for an AUW of 3.9 Kg (almost 8 pounds).
Among which 2 4S 4500 batteries (almost 1K

I am going to convert my standard quad to a X8 configuration.
Are there any particular points I should take into account about either mechanical or electrical setup ?
I intend to use smaller props on top and larger ones on the bottom as it appears f

I have this APM2.5 board, configured for a quad v2.9.1b and uses it regularly for a few months without any problems, until now...
