Mavic Pro Battery Mod

[beanbubba]

it's all what makes the hobby that much more fun,trying to just figure it out.

A bit off topic, but since we have everyone's attention, I got this message a few minutes after takeoff on my last run and it never went away for the flight duration. Never seen this in-flight before, only on the ground next to big metal objects. Any ideas?

Never saw that one either. Maybe you should do a compass calibration anyway.

If this is with battery mods added? If so it makes a lot of sense. When you pull energy out of batteries they can become a huge source of electromagnetic interference. So your compass is likely confused since the EMI during flight does not match what you had during the idle power compass calibration.

You made it sound good but that's not what it is.

all newer drones work all on firmware not hardware like old NAZA based DJI, so the right mind can rewrite the firmware, i have heard people complaining about DJI privacy rules.... how you upload all your info to them like the cloud, and they just dont want to do that.......so.......just examples, but i think if you want to add bigger props or a better antenna, thats ok, i quess we all need a better explanation of the rule, so none of us cross that line,

most hobbies are about tinkering, and making a better mouse trap

I have seen the dark side,,,,,,and its so wonderful, to bad we cant share this, i was wondering what they where talking about, so i searched and found.........wow i was correct, the same as NAZA, but A3, it all makes perfect sense now
if you had audrino drones like i had, its only like having MISSION PLANNER

What config you're flying? How much add on weight? Flight mode? Tilt angle? Wind?
I had the same last week. 5200 on the back, good headwind and flying 58km/h in p-mode...No errors with tailwind. This error came with too much tilt.
Edit: it showed up when passing 52km/h in headwind. Gone again below 50. Was reproducable during that flight leg.

Anyone know where that ole frowning clown(Maclak) has been?

You missed me, admit it!!
Been busy, the dark side..

I think CyberNate had similar and had to replace a compass.

I think CyberNate had similar and had to replace a compass.

First investigate the conditions and try to reproduce.
I could not reproduce it during the same flight in S-mode with much higher speeds.
It is possible the compass gets messed up with all the extra cables in there and the associated em fields.
Remember how many people got paranoid in the beginning because they thought even wearing a watch could mess things up? Look at some of our remotes now!! All packed with holders, batteries, boosters, cables! We re pushing things a bit.

Here is the flight and wind data. Using dual 1500 lipo on the side.

Ok, this is different. Did you feed the Mav a "red pill" somewhere before this flight?

No, 2 blue pills.

Haven't had good weather yet to continue testing.

Oh I was just bringing the page to the top so you don't have to look thru 4 pages to find it.

It's been storming here about all day.

As a few others have done read this thread back to front and also used it as reference. Great thread!!

Well, I think I have taken everything on board and just about to embark on a test flight, short runs and within sight- 200 mtrs or so- see how everything works.

I have opted for keeping the adapter on at all times, If there is an anomaly between batteries or power used then I may have to go the route of whoever soldered the adapter to the MP's terminals.

Loving the dual lock product- Amazing!!!

Well here's a few pics of my bird...

Got Lipo's on at the mo 2.2mAh - but did also purchase some larger 4.0 LiHV's, but see how we go with the Lipo's first
