If a majority of instructors had there students fly in closer instead of out in the north forty, they would not need to do this. I would not be surprised if every student pilot who has trouble keeping and eye on his plane, now looks down at the TX, then looks up? This little trick is cute for instrument training but looks like a bad idea around this hobby.
What happened? Well I lost track of the plane, so I took my eyes of it and looked down at tha transmitter. You did what?
