Yup, found this out in my front yard. I was able to slow down descent and guide the bird to the landing pad. Now I know not to RTH when near water and less than 20 meters from home pointIn the P4P manual a RTH , whether it be failsafe , smart or low battery mode, if triggered within 20m of the homepoint will result in the AC landing.
If the RTH is triggered while more than 20m away from the home point it will ascend to the RTH height set and then come all the way back to the home point
