All the arguing over needing one or not needs to be put a side. Some people need just a little assistance. Whether it be the reflexes aren't what they use to be, or orientation, or sight. Nothing wrong with a little help. That being said, I would recommend an Eagle Tree Guardian. Put it on a switch and in 3D mode one can fly normal with a little bit of assistance and when one gets into trouble flip the switch to 2D mode and it will return the aircraft to straight and level flight, dissorientation over! Resume normal flight!</p>
