Only one servo works f405 v2 wing about inav HOT 6 OPEN

The first thing I would check with a multimeter is remove power and check continuity between each pair of adjacent pins.

If you find continuity between pins, also check continuity to ground.

Sounds like mixer issues. Can you please attach a screenshot of your mixer.

Also double check that the motor and servos are actually attached to the outputs shown in your mixer.

On closer look s3 (elevator) and s4 (left aileron) are the only servos working, the rest including the ESC/motor not working when moving transmitter sticks.

S1 ESC has Vx pin removed/disconnected, (as per matek instructions)

servos have Vx connected

Receiver signal wire in on Tx2

More and more I'm thinking it has to be faulty solder points (although I think I soldered well) --- what would be the best way to check--hook up voltmeter and move the radio sticks?

Vx2 to Vx pad bridge created--all servos now working -- thanks for the pointers.

Now just S1 ESC/motor doesn't respond to throttle stick inputs on Tx(everything in iNAV indicates it should), have Vx disconnected in the ESC S1 pins.

I'm unable to calibrate ESC -- not allowed to turn on motor test mode and motor value at 1460.
