I am 87 and blind in one eye. I need a little help in determining the speed while landing. I also sometimes lose sight of it in flight. I wish I could get a stabilizer to work with the vibration of a gas engine.
With an electric I use the Guardian. If I lose sight of it I just turn on 2D and throw the aileron hard over. It will then just turn around where I can see it. G in 2D wont let you turn it over.
I think technology is great. I expect to be soon fitted with a pacemaker. That way I will be able to fly a few more years. I dont expect to ever be able to remove it.
