So..... I've had my HS720 for several months and have enjoyed the heck out of it. I had one catastrophic crash in the beginning of November 2020 which took out three of the four control arms. I purchased replacements from Holy Stone, installed them, ran a few test flights out at the ball field and patted myself on the back for a job well done. The drone worked flawlessly for a few months until...
On Jan. 2, 2021 I went out to a local lighthouse to fly and film. It was COLD with a mild but steady breeze. Did all the normal preflight stuff then used one touch takeoff and ran her up to about 30 feet. As I ran a test circuit to verify control response etc. the drone suddenly stopped responding to slue left, slew right and yaw left, yaw right - in other words: no response when either stich was pushed left/right. Forward, backward and up, down input (stick forward, stick backward) response stayed solid. I maneuvered her back to me, did an in hand landing and went home to warm up. The next day I flew in my front yard to see what was going on and the control response issue would come and go every several seconds.
Now - when I replaced my armatures I had to scrape off some sort of brown resin that had been applied over the ANT1 pads which I scraped off with an X-Acto knife. So is it possible that one antenna is the pickup for forward/backward stick input and the other antenna is the pickup for left/right stick inputs?
Any suggestions on what to look for where would be GREATLY appreciated! I should forewarn you that I'm not going to replace chips or processors or anything like that. I'll bridge a cut etch on the board or re-solder cold solder joints etc. but I'm not into open heart surgery
I've attached an image of the circuit board before I attached the new antenna wires and the video of Fort Adams (just for fun).
