"Reading your post again, electronics (drones) don't always like RF radiation, bad thing could happen! What tower and arials are you flying around? Are they transmitting?"

"Does the video stop working when it decides to go on its own way?"

"Set up a wireless station with same details as drone, if you see the same mac connecting to it every time its possibly an attempt, wich can be investigated further."

"It doesn't seem to have any security on the WiFi, if you were my neighbour, I would probably have some fun with you too! (https://hackaday.io/project/19356-reverse-engineering-a-promark-vr-...) would recommend setting up a wireless AP with the same…"

"Let me know where I can help, have access to lab psu, ossiloscope, apm2 and apm 1.4 (good for testing, learnt allot trying to diagnose baro drift) maybe PM from here?"

"@DavidJames That's how it's done :) could you do the same test with telemetry connected, servos moving and power from a single lipo? (from my measurements those 2 components generate the most noise)"

"On topic: if it comes with an aviation certification (FAA/ICAO or similar) I would be more comfortable sitting as a passenger in a plane without a pilot!

Ps. I am unaware of any certification on either units, so still prefer a human pilot."

"Yes, and where is the specs/certifcate for the implementation?
Your fridge might have the best compressor in the world without doors (north pole = great performance, desert = bad preformace)

Put your money where your mouth is and pay to verify that…"

"Have you tested this assumption with an oscilloscope?
Assumption is free. (might be the difference in price tag!)"

"I read through all of the apm2 sensor data sheets the other day trying to determine the accuracy. The interesting thing I remember is the the accuracy is tied to the quality of the power supplied to the sensor (the MEMS sensors have analog…"

"The esp WiFi module should be mounted up right for best range. Google PCB arial radiation patter."

"It was set up over IP connection through an access point plugged into a laptop with ethernet, let me know if you need help!"

"I have had great results using a xbox remote and a Wifly
