SeanTheITGuy pwm1,2,4,3,5v,gnd. could be run to a 4in1 esc.

SeanTheITGuy You would need a flight controller in your plane. The receivers have no PWM outputs, so you couldn't hook it directly to servos and ESCs. If you have a flight controller, then yes.

SeanTheITGuy Yes, using the project esp_wifi_repeater (on github) you could use this as a wifi range extender. It's just an esp8266 board that's been customized for this one "testing" purpose, but you could use it for any 8266 project.

SeanTheITGuy The information is not correct. There is no button. This unit is configurable through smartaudio only, which makes it sort of a pain to use. It's meant to be a pre-assembled part with a tiny board camera, hence the tiny, poorly labelled solder pads.

SeanTheITGuy They have an M6 thread, the CW has a 8.5mm shaft, and the CCW has a 7mm shaft. They are a little odd for props, and I have taken to boring out the hub of old props I had on hand to fit. These motors are spares for the Xiaomi 4k camera drone, so any props meant for that should work.

SeanTheITGuy It's not super tidy of a soldering job, but yes, the capacitors are all tied in parallel as they are acting in two banks to be filtering caps. They could have used a single larger cap per side, but the form factor and size restrictions of the device limit that ability.

SeanTheITGuy I would never trust the BEC built into an flight controller. Use a PDB with purpose built BEC circuitry, and run your flight controller and IMU sensors from that. If you do that, VBAT is irrelevant.
