Hello all, I tried searches on the forum and Google, but didn't really find what I needed.

I've built several quads i9n the past, but this is my first mini. Here is my setup:

230mm 5" on a 3-d printed X-type frame
x2204 2300Kv motors turning 5x3.5 3 bladed props
Akk 30a 4 in 1 ESC running Dshot600
3s 3000mah @ 30c
Speedybee F7v2 FC soft mounted
Frsky R-XSR receiver
Neo m8n GPS/Mag

accelerometer and mag have been calibrated
Baro is covered with breathable foam.
Props are confirmed to be in the correct position, and all motors are spinning in the correct direction.
all solder joints double checked and are good.

I have tried both Betaflight and Inav latest firmwares, with the same issue on both.

Here's what happens, whenever I arm, motors spin at 6% like I have them set, but any throttle input at all, and the motors quickly ramp to full speed, and only disarming will kill them, as after they do this, there's no throttle response at all. I will note that in Betaflight, sometimes it will let me go to about 10-12% throttle before it runs away, while inav runs away at any throttle input. Doesn't seem to matter which mode I arm in (angle, horizon. or acro).
On the bench, in configurator, motors respond as they should, both with and without props.
Everything responds normally in the receiver tab as well.
I've tried increasing filtering in BF, no change.
Looked through a cli dump and blackbox logs, but see nothing out of the ordinary.
I have the same FC in a 450mm quad running inav, and it behaves normally.


The only thing I haven't done is update bheli on the ESC, but I doubt that's the problem.


I haven't flown this quad yet, as it seems as though a broken frame is inevitable. Any insight or thoughts would be greatly appreciated!
Thanks in advance!
