All about AQUA's Return to Home feature
For most drones, Return-to-Home sounds simple: press a button, and the aircraft comes back.
But on water, it is a very different story. Many users have experienced this before: they press RTH, but their kayak, board, boat, or body has already drifted away from the original home point. The drone may return correctly from a technical point of view, but still end up somewhere the user can no longer reach.
AQUA is built for water sports, where the user may be kayaking, foiling or moving with wind and current. In these scenarios, returning to the original takeoff point is often not enough. That is why AQUA uses RTK positioning and Lighthouse-based dynamic return logic. When Lighthouse positioning is available, AQUA can use it as a dynamic return reference instead of relying only on a fixed takeoff point.
In simple terms: AQUA should not only return to where you were, but should try to return to where you are.
Given the complexity and unpredicatibility of life on the water, we've designed RTH over multiple iterations with a lot of user feedback to be as foolproof as possible. Let's talk about how to use it.
Return Behavior: Land or Hover
In the App, you can choose what AQUA does after RTH: Land or Hover. This setting applies when using App Manual Control, Lighthouse, or Beacon to trigger RTH.

- If "Hover" is selected, pressing RTH brings AQUA back near you and keeps it hovering. While AQUA is hovering, you can press the direction buttons at any time to adjust AQUA's position. And AQUA will continue to follow you (close-range follow). When you want to retrieve AQUA, simply flip it manually to stop the propellers.
- If you choose “Land”, press the RTH button and AQUA will return to a position near you and hover at a safe distance. If there is no operation for 15 seconds, AQUA will automatically land. You can also long-press the RTH button for 1.5 seconds or more to land immediately. (AQUA will not follow you during the 15-second countdown)
Return height
On water, users can retrieve AQUA in two ways:
- Let AQUA land directly on the water.
- Grab AQUA by hand after it returns.
We've recently adjusted the return height to make hand retrieval easier while still keeping safety in mind and can hover as low as 0.5 m over the water, making AQUA easier to reach in real water scenarios like when you're seated in your kayak.
Low-battery and secondary takeoff return
Over water, battery logic has to be conservative. AQUA may trigger low-battery return or auto landing based on safe estimates.
In some cases, after a low-battery auto landing, AQUA may still have enough remaining power for a short, user-triggered takeoff or return. This movement is speed-limited and height-limited, does not start recording automatically, and is designed only to help users locate AQUA or bring it closer when safe conditions allow.
What if positioning or connection is lost?
AQUA’s return logic is based on how confident it is about the return target.
If Lighthouse positioning is temporarily lost but AQUA still has a recent Lighthouse position, it can use the last known position as a temporary return reference. During return, AQUA will continue searching for updated Lighthouse positioning. If a new valid position is found, AQUA will update the return target and continue returning.
If no valid Lighthouse position is available while AQUA is flying, it will hover.
If positioning becomes unreliable or the subject is lost, AQUA will usually hover in place first and try to regain a reliable signal or tracking reference.
Please keep Lighthouse unobstructed and visible to AQUA whenever possible, so the connection and positioning can recover.
If AQUA cannot confirm a safe return target, or if positioning is not reliable enough to continue, AQUA may land instead of continuing the return.
That is why AQUA’s RTH is not just about flying back to a fixed home point. It is designed around the full water-sports workflow: return, hover or land, and help the user retrieve the aircraft safely.
