Help on Jdrones 20amps ESC

Hello,

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

Two Batteries in parralel Vs One

hi all,

I gathered information that i would like to share in case it helps anyone.

Test: Fly to 4 ft and enable loiter until low voltage alarm sounds with the following batteries.

• Test 1: Battery A 5000 mah 3s = 11 Minutes
• Test 2: Battery B 5000 mah 3s =

3DR 1.2 gig FPV TX Freq issue.

Ok so I bought the 1.2 gig setup for my fpv with the osd they sell. I was curious what freq it was transmitting on and to my amazement 1080.000 lets call it.  This is not right as the legal ham band is 1.240 GHz - 1.300 GHz.  I certainly am not legal

Best quadcopter camera for photography and fpv at the same time

hello,

I currently have a Gopro black edition that i use for FPV and photography but people don't like the "bendy" photos from the Gopro.

What is the best standard digital camera with Gopro like features that will take photos using an intervalometer an

Custom Quad Copter Setup without Recompiling APM Code

The proposed change in code would allow APM to address every custom quad copter layout (scope limited to fixed vertical rotors).  I'm asking for input before doing a pull on code to make this happen. So please speak now or ....

Your quad may be custom

Mission Planner Log Keeping w/Date and Times

Just a thought.  When I review my tlog or my APM log I notice the time is related to zero and marches out to the right in time in seconds.  Although this is nice I would like to see times in the time zone you are flying in with Date and Time (HH:MM:S

Flight Modes?

Hello Friends,

APM2.5 Firmware version 3.0.1 PID tuning

hi I have apm2.5 quad running 3.0.1 and I can not get it to fly a basic square or any mission in auto. What happens is it will suddenly drop and then I stop it by going back into stab mode. I gain more height and try again it will then fly the first

APM2.5 firmware version 3.0.1 Quadcopter

My APM 2.5 seems to drift and I can not get it to go into auto trim mode. How is this done. Also I have a issue with guided. I guessing guided is when u program flight planner to do a mission and then its meant to do that. Mine just goes mental and t

apm reinitializing and not arming

my APM1 doesn't want to init, I use it with ARMING_CHECK 0 so it will pass all the annoying checks, but he keeps on failing to initialize , any help

APM Mode Values

What is the min. recommended value to be away from the PWM limits of other modes?

Even though the Flight Modes will switch within the Mission Planner, I have found during a test flight a couple of my mode values were too close to one another.  I reali

RTL

1. when  programming a mission and doing an RTL waypoint, it will use either the rtl altitude in the flight screen for your waypoint or use the default RTL alt in the flight screen if this is enabled.
2. Now for the ch7 RTL altitude it will use the value de

Votage usage

hello,

i want to figure out if my 3dr voltage monitor is working correctly

I complete a test with 2 of the EXACT same 5000 mah 3s lipo batteries.

I have a cheap low voltage alarm on the battery also. I launched to about 4 metres high and engaged loiter

Loiter Problem

Today I was testing the Alt Hold and Loiter modes.  When I switched to Loiter for the first time, my hexacopter locked into position.  After Loiter, I switched back to Stabilize.  Everything seemed okay.  Although, when I went back to Loiter, the hex

Caution pls with incoherent default mission planner commands : crash and material damage is likely if you are distracted

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

Calling All Custom Multi-Copter Pilots!

I plan to do what is called a "pull" to made changes to the custom code regarding custom shaped copters.  

This change in code would only impacts irregular shaped quads, hexas, and octas when the pilot specifically opts to go custom versus the default

Accelerometers "Calibration Failed"

Hello,

I have a problem with my APM2 with the calibration of accelerometers use the M.P. 1.2.67, and when I do the calibration, as wiki procedures, it gives me the following error "Calibration Failed", I run both in MP mode in the CLI.

altitude hold drift

when i fly fpv i always fly first in stabilize to about 30 metres and then enable alt hold. Works fine and makes flying fpv easy. However sometimes the height of the quad drifts to say 10 metres high and i have to switch back to stabilize and increas
