I have been building and learning FPV drone in the last couple of weeks. It has been a bumpy journey my me. I lost my very first 5-inch quad in a tall grass field in the first 15mins flight. Now I settled on my second quad which is a 3-inch cinewhoop. It is a solid build, with many crashes it does not fail on me, except this time, after a gentle landing on a wet grass field, I lost my video feed and control.
Before I continue my post, here is the FPV build list.
◉ Flight Controller & ESC: MAMBA F722 MINI DJI F35 3-6S FLIGHT CONTROLLER STACK
◉ Video Transmitter & Cam: CaddxFPV Vista Digital HD FPVSystem
◉ Remote Controller & Goggle: DJI FPV remote controller and goggle
◉ GPS: Beitian Dual BN-220 GPS
◉ Beeper: New Vifly Finder 2
So, I brought home my quad, and after some inspections, I found that the 9v pad lost voltage. It’s 0. Here is the illustration of the issue on the FC.
Clearly, this pad has been damage due to the moisture.
After checking the vista specs, it takes input power: 7.4-26.4v, so, I decided to cut the 9v red line and connect to the VCC pad on the right side of the board. My video feed and control is back online again.
If you are asking me why you learn to fly FPV, it’s simple. You could fly. Share some of my FPV training videos.
