There's a pretty regular stream of posts from beginners listing parts and asking for feedback, I thought I'd post some pics and specs for a quad which I've partially rebuilt three times, noting some…Continue
"I'd avoid a 78xx regulator, they are very ineffecient. I'd recommend a buck-converter based regulator, like most discrete BECs are. I use one of these to power my gimbal, video tx,, and minimosd from a 4s."
"I would not assume that the battery negative is the same as the BEC ground.
On a somewhat related note, I would consider connecting the batteries in full parallel; i.e., tying the +s and -s together (with high current wiring/connectors). This…"
"I would second Joes opinion. The second ground is definitely required. I'd begin by swapping escs to see if the problem follows.
Also, once both grounds are connected as needed, you will need to recalibrate the escs if you originally did it…"
"By using Loiter mode, you're having the software compensate for whatever the problem is. The fact that Loiter can compensate probably just means that the leveling needs to be re-done. You should be able to fly it in…"
"Did you do the first step of the accel calibration with the craft perfectly level? I like to use
A bubble level between the arms.
Also, make sure the motors are connected to the correct outputs.
Posting a log file may be in order if you're…"
Make sure you have uploaded the correct firmware (y6).
The yaw when you start it up should reflect true compass orientation, not necessarily zero.
Did you perform esc calibration?
Are all of the props on correctly and motors spinning in the…"
