APM2 w/ 3DR power module displaying wrong voltage
Started this discussion. Last reply by Glenn M May 4. 3 Replies 0 Likes
I've just loaded new firmware on to my APM2.5 and restored my saved parameters for this setup, but the voltage reading is displaying lower than it really is. Eg mission player will display 16.2V when…Continue
Altitude drop after forwards or backwards movement in ALT HOLD
Started this discussion. Last reply by Randy Apr 29. 6 Replies 0 Likes
I've got a problem with my copter where it will drop in altitude, following a forward or backwards movement. It will recover back to the original altitude once I stop. The drop is generally around a…Continue
Flying close to HV power lines
Started this discussion. Last reply by Josh Potter May 11. 8 Replies 0 Likes
Does anyone have experience flying in close proximity (within 4 metres) to High Voltage power lines? Specifically 110kv towers.I have read that the lines can output a certain amount of RF, but I'm…Continue
Tightening up Yaw
Started Mar 23 0 Replies 0 Likes
I'm running a quad, and I notice that my yaw can and does drift a little quite often. Eg if I take off and loiter, the heading will sometimes drift around by as much as 15 degrees.I would like to…Continue

Bill Salopek replied to Glenn M's discussion 57600 or 115200 baud?"I am new to this, and am wondering the same thing...I connect at 115200 using the USB cable directly into the APM 2.5, but then 57600 when connected via 915mhz telemetry.
So the questions remains...what re the pros and cons to 115200 on the…"

It's most likely I'll make one up with 16mm square lengths of wood to begin with. Does it matter if the central angle is not 90 degrees?…"
Glenn M replied to Forrest Frantz's discussion Building Copters with Round Tubes - Stronger, Lighter, Easier to Mount Motors than Square Tubes in the group ArduCopter User Group"I'd quite like to build a quad using uncut round cf bar like you have done. I'm thinking if I build the central part exactly the same as yours, and just shorten the bars on the outside so that they only extend to the ends of the…"

"I had to manually edit my voltage divider to get it to correctly display voltage again after installing 3.0 rc1. It was off by about 0.5v"
Glenn M replied to Glenn M's discussion APM2 w/ 3DR power module displaying wrong voltage"I tried all of that first unfortunately. It's almost as if the latest version of missing planner is the problem. It throws an error when I try and put in my APM Input voltage."

I hope it can solve your problem!"
Glenn M replied to Glenn M's discussion APM2 w/ 3DR power module displaying wrong voltage"Anybody?
I've noticed that my current consumption is displaying 5A at idle too, which I'm pretty sure isn't a correct value."
Glenn M replied to Geir Engebakken's discussion Loiter issues - big circle"I'm pretty sure that this is caused by your compass declination needing adjustment. I've had the same issue with mine. The declination from the website isn't quite correct.

Glenn M posted a discussionAPM2 w/ 3DR power module displaying wrong voltage
I've just loaded new firmware on to my APM2.5 and restored my saved parameters for this setup, but the voltage reading is displaying lower than it really is. Eg mission player will display 16.2V when the true voltage is 16.6V.I have it set in mission planner to:Monitor 4: Voltage & CurrentSensor 4: 3DR Power ModuleAPM Ver 2: APM 2.5 - 3DR Power ModuleIs there a way to fix this? I've tried setting the voltage divider differently in the advanced parameter list, but it looks like this setting…See More
DeveloperRandy replied to Glenn M's discussion Altitude drop after forwards or backwards movement in ALT HOLD
"Sandy,
Great, please tell us how it goes.
I think the pressure difference is between the top and bottom of the copter. I suspect that if you put your apm on the bottom of the copter (which i know is very…"
Edward (Sandy) Abernethy replied to Glenn M's discussion Altitude drop after forwards or backwards movement in ALT HOLD"Hello Randy,
I have also been perplexed with 2.91b alt_hold, watched your videos.. Hopefully, this case mod will equilize the "pressure bubble".. For vibration control, I have a 70 gm copper plate sandwiched between the .5"…"
DeveloperRandy replied to Glenn M's discussion Altitude drop after forwards or backwards movement in ALT HOLD
"Actually i think so yes. I jumped to the software solution but actually it's a physical problem so a physical solution to equalize the pressure above and below the copter is perhaps best."

Burning Man From Above

Here's a little video I've put together from the recent Burning Man, which is a week long ~50,000 person arts festival held in the Black Rock Desert in Nevada.
I shot it using my small homemade tricopter with a hard mounted gopro using FPV.
