Hey All!

Hopefully I am not asking something that hasnt already been asked but I have not found a solution that has allowed me to DIY so I think it is time to ask someone who can help!

I would consider myself a low skilled moderate, I have loved learning to fly TinyHawks, TinyHawk Freestyles and an IFlight Nazgul but wanted to make the jump to digital with something with a more stability and control. I just got a TBS Tango 2, a shiny pair of DJI FPV Goggles (V2) and a GepRC CineLog 25 with the CADDX Nebula Nano and Crossfire Nano RX.

Naively, I wasn't expecting to have to update 4/5 different systems to get this drone off the ground but after an evening and part of a morning of forum surfing and Youtube-ing, I got it to where I have it bound to the Radio, bound to my goggles, set up the model and the mixes on the Radio, am transmitting signal to the drone, and receiving telemetry back in the goggles. I plugged a battery in and the motors turn with no problem, and while on the ground roll, yaw and pitch all seem to be doing what they should be doing. Once the drone is off the ground, I can make slight corrections to it to keep it in place and can move slowly on all axes and take it 10-15 feet in the air, but once I cross a threshold of somewhere between 5 and 10 degrees of pitch or roll, it either spazzes out and flips into the ground, or loses power completely falling out of the air. 

Ive tried to troubleshoot by holding it in my hand and it does not cut off when I pass those degree thresholds, and when in Acro (Not Air Mode) it seems to have the most success around 10 degrees but in Air or Angle mode it will fall if I push it past a slight incline making me think it is some kind of an issue with a motor that is malfunctioning, a failsafe that is being overly sensitive, or an issue with the gyro. I dont want to reset it to the factory CLI dump since I took so much time getting it to where I am already but it seems like that is the next step unless you guys have any other ideas!

Thanks in advance for your help!

Might be a setup or a hardware issue. Any backbox logs? Or videos. Did you play with the pid tune or filters?

With DJI you will not get warnings on the screen either that could help indicate the actual cause.

Hey Kafie, Yes, the lack of OSD warnings in the DJI goggles was pretty frustrating and I have honestly never used the black box functionality so I am not sure how I would get to that, Ill look into pulling those files and I would assume I will need to take another flight to log more data since I dont have it configured and I already pulled the battery on my last flight?

I did not play with any PIDs or Filters, the only changes made were to :

OSD to set it up before learning it sucks on DJI Goggles
Modes to setup the armswitch, flight modes, and beeper, etc
Reciever tab to set the channel map to TREA1234 otherwise the control scheme was wrong.
Ports Tab to enable UART2 as a serial port to have it recognize the preinstalled Crossfire RX

Apologies on my barefeet, but here is a vid of it doing its thing and I had failures at 0:06, 0:21, 0:38, 1:04 and 1:24 where they it is either dropping out of the sky or spazzing and flipping over

The above is after I flashed it with a CLI Dump from GEPRC's website, it does seem to have improved the angle I can fly to, but now it seems as if it is more random.

It says the video is unavailable?

Sorry, should be good now!

Looking at the video it seems like one of your motors or esc’s is causing the issue.

Do your motors feel hot when if drops?

Do you have a snapshot of your blheli settings?

So I just hooked it up with betaflight and a battery and tested the batteries one by one and motor three just got smoked after raising it above maybe 30% so I think I found my problem....

Is this a something that GEPRC will own and make right or do quad companies generally have a take off warranty where once you fly it your warranty is void?

I would contact them regardless. Just tell them one of the motors smoked on the first few flights.

As long as the motor does have an external damage, not much they can hold against you.
