The H-480 Home location is “dynamic”. It moves as the controller moves. If you walk (example) 20’ after launch the Home point follows the controller. When RTH is activated so is Smart mode, and when in Smart mode the H should not come any closer to the controller than 15’-17’ or so. An RTH landing will occur outside that distance.
The only time it will automatically RTH to a point closer to the controller is when RC link is lost with the controller, at which time it will return to the last “known” location of the controller and hover until re-establishing link or the battery becomes depleted, when it will land itself.
If you want to use RTH but land closer, toggle the mode switch as the H gets close to Home and place the switch in Angle mode to interrupt the RTH cycle. From there you fly it to wherever you want to land it yourself.
