Hey there! Thanks in advance for taking a look at my request for help.
I have a large quadcopter on 3.7dev, it has been tuned but I am unsure if it needs to be tuned (or sable enough to tune) with the attached artwork.
Pixhawk 2.1 Cube
My main goal is to have this craft safe to fly, it’s quite unstable with the attachment.
The copter seems very stable without the attachment, but it’s not very fast or nimble due to it’s large size.
Would it be safe to re-tune with the attachment?
Is the craft underpowered ?
Should I consider an X8 over a quadX ?
Here is a flight video with the payload attached, might help in referencing the attached log #48:
