Not 100% sure. The remote is the same, the app is the same, probably the PX4 side is the same on both of them. Mantis Q has 1 axis the gimbal, just up and down camera like on Breeze, it probably has some digital stabilization, I have not paid attention to it, its not a serious videographers...

Yeah, buy one, lets get the scene moving :) You can snatch them up pretty cheap on eBay if youre lucky. Like this eBay deal (open the ended item, not the one eBay promotes as alternative), someone got a very good deal, full drone package at a price of a battery (the battery was probably dead as...

Yes it is not likely that Yuneec is going to release anything to the public. Because even military drones are based on the same (good old) technologies that were/still are used in consumer drones, that would make their current products vulnerable for whatever possible exploits, that is just one...

Given that IMU is basically an electro-mechanical device (MEMS) then its probably possible that it can get damaged if whacked. Not sure if just crashing a drone is enough, maybe falling on the concrete is but then drone itself would be broken as well.. And then it also has quite limited lifespan...

The IMU chip is on the GPS board, this LGA16 chip you made picture of is ICM-20602, that is the IMU: Datasheet at TDK: icm-20602 I recall reading in drone forums that by design IMU is often required to be dampened from vibrations of the frame and preferably away from electromagnetic...

Wow, your params file contains alot more parameters! The screenshot of mine I posted earlier its the entire params file in my case! I am getting alot of "error finding param:" messages when my drone is initializing, I just did not paste all that bloated log here so not to confuse ppl here. But I...

Have you tried to figure out the thermals and add the 2nd antenna? Is there anyone else interested in such developments? I believe thermals problem can be solved by adding very slim radiators where it is needed. They have done absolutely nothing to cool the chips, definitely there is alot of...

I can confirm that params file on the internal SD card has these values in it:

If it cant go through compass calibration I would suspect a dead compass, I know mine was dead because I finally noticed that the little 3.3v regulator that powers the compass BGA chip on the little compass PCB was heating up like crazy once drone was powered on, noticed that by accidental touch...

Youre welcome. Yes there are lot of commands to explore, I have not done more research myself yet. What is the issue that you have with IMU? Have you carefully looked through all the errors that get logged in the console as the drone is powering up? There could be lots of useful info. Also if...

Well yes I guess it needs more detail. But I was not trying to write a complete tutorial, I assumed people doing drone repairs have understanding about such things. I can assure you that this procedure should not be performed by an absolute beginner because just taking this drone apart is quite...

To connect to UART 8 you need to connect to pads marked TX8 and RX8 on the PCB. Sorry did not take pictures of every step because at that point I was just blindly exploring the board trying to understand what can be found. The compass can be calibrated independently from IMU. That is what I...

I am going to answer my own question. Got sick last week and had some time at home to look at this issue. Hope it helps people here as it seems to be an unresolved problem. You can calibrate IMU permanently through UART shell. The downside is that the drone needs to be disassembled and...

Hello. I have this problem with gyroscope. When I power up the drone everything is fine except this error: Gyroscope initialization failed, please restart the drone to take off again. Then right after that it shows the Drone State window where it shows that IMU is Uncalibrated Sure enough...

Sorry to hijack the thread, but I am one of those people with a lost WiFi password. The QR code sticker is gone. I know its been awhile but I would appreciate if you could help me to retrieve the WiFi password from the drone. Already took it apart a bit and pulled the internal SDCard, nothing in...
