Auto Return-to-home at user defined battery level?

So I’ve read several of the RTH threads and SD2 support info and I’m not coming up with an answer. Most of my SD2 flying will be beach launching and flying over water while I’m kite-foiling or wing-foiling. In the middle of rough water conditions even operating the beacon through a waterproof pouch could be difficult. The same could be said for activities like surfing or whitewater kayaking. With my Staaker follow drone (no OI at all), the drone automatically initiates RTH to the original launch site at 40% (or if the drone-beacon connection is lost) in it‘s “water flight” mode. It works surprisingly well. Heck, I could have a big wipeout that would require 5-10 minutes to recover from while the drone is waiting for me with the battery draining away. So is there any user definable auto-RTH function that you can set at the start of the flight available right now? Hopefully this is not too dumb a question🤪

Here's a screen shot of the Low Battery procedure from the manual (v3). AFAIK there's no way to set the RTH battery %. Also, I would make sure you set a Home point before takeoff as you don't want it landing in the water!

Ok, got it. Thanks! I’ll have to see if I can lobby the Skydio team to add a user definable RTH based on remaining battery life. When you’re out on the water with your hands full while foiling, you’re never going to even see or hear a message, and even if you did you’d have limited ability to operate the beacon while getting tossed around in the water. You don’t just stop mid-foil and pull out your beacon, any more than you would while getting pounded in the impact zone while surfing.

I also wonder if the current SD2 RTH criteria of alerting the pilot when there is minimal battery left to make it to the “take-off” home point (most often the waterfront spot you launched from) accounts for wind speed and direction ?? Any experienced drone pilot knows that can be a huge issue for RTH succeeding or not,....aside from OA issues. When using my Staaker follow drone I usually adjust my riding session to make sure I don’t end up significantly down wind of the home point, but that’s why having control over remaining battery % for RTH initiation, allows you to have some control over your RTH safety factor.

Over water self filming in some of these water sports is often more about RTH issues than optical avoidance issues!

Yeah, it doesn't sound like they had your specific use case in mind when designing this thing. Also, as to the taking into account wind speed and direction for the RTH %, no drones do that as far as I'm aware. Hopefully, they'll update the software to allow for changing the RTH % and automatically doing the RTH once it hits that %.

I have similar scenario with backcountry snowboarding. I had sent a request to Skydio and they said the workaround is to manually set a homepoint. So when you first launch once you get GPS lock, tap on the map and bring it full screen. Then press and hold on the location where you want the homepoint to be. I believe it does have the smarts to know how much battery it needs to get back to the home point. I haven't been able to test it out unfortunately because I generally don't have cell signal when filming in the backcountry thus I can't really tell from the map where I'm setting my homepoint. I'm definitely going to try it out the next chance I get so I'll report back.

Lucky you that you get Data coverage when you backcountry snowboarding.
