New Frame and Motors - New high current problem

[warped canyon]

I recently moved my electronics to a new frame and changed out the motors.
On the new build, I'm drawing >20 amps just hovering. The current draw is overheating the batteries and causing the O3 to drop off line, presumably because the 10V is dropping too low.
On the bench, I can run the motors to full speed with only 1-2 Amps draw.

I am running a Skystars F7HD PRO3 Flight Controller OSD KO60 60A stack.
My motors are XING II 3110 1250.

I've attached my CLI for reference.

Any ideas as to why I mig

Motors with no load will draw less current than motors that are spinning a prop in air

It's also possible that there's a tune issue that's making them draw even more current from trying to spool up/down too fast

Those are massive motors. What kind of a quad are you using them on?

A 7.5" cine build using the MOZ7 frame.

Yeah that's really big for the size

Almost twice the usual size

But that does not explain the current draw.

Have you looked at the datasheet for the motor?

Isn't the typical motor for a 7" a 2806.5..

[willow saddle]

this frame not stiff enough. could be vibration and filtering issue. could you make a log?

[warped canyon]

Yes.

[warped canyon]

Sure. But Im not flying a 7". It is 7.5 with steep pitch props.

So why does ~20A current draw suprise you then? Assuming you're hovering at approx 30% throttle, each motor will be pulling roughly 5-10A, so, 20-40A total which I assume what your figure is

[warped canyon]

At 30% throttle I would ne moving about 40 mph.
This will over at 10% or lower.
This is my 3rd 7.5" drone.
