Well I can tell you something. I think I **** my pants today.I was able to remove the battery. I don't think it's stuck to the tray anymore though. I have not tested the new antennas yet let us know how it goes. My stock antennas were replaced by autel a few weeks ago and already one of the replacements started to crack that's why I decided to replace them myself.
I went out to test the antennas. I am not sure if one of the cables inside the controller got damaged and is not receiving or if it's the external antenna that simply do not work. I mean, with or without the antennas attached, I lose connection at the same place.
I decided to do a mission of a house at 100'. Once it reached 70' I got disconnected and it did not connect until it started to land. I had 0 control over my Evo. It was the most intensive 12 minutes of my life. Once it landed I decided to take it out for a spin to see if it was a fluke. Since I am in a neighborhood, I wanted to achieve 250' but after 70' it disconnected and kept gaining altitude without input. Luckily I was going up slowly, so it didn't reach above 150' before RTH kicked in and landed.
When I get home tonight, I'm sticking the OEM ones back and hope they didn't get damaged in the process. If not, Autel will get $300 for a new controller.
Update: It seems I forgot to set the camera settings to take photos while doing the mission. So I have nothing to show for all this effort. heh.
