I do a fair amount of very short flights while hiking in canyons, and often just launch without my iPad. This probably stems from my long history flying aerial photography missions with my camera equipped park flyer plane with just a simple "blind" transmitter. Of course the downside is you can't see what you are photographing and you can't get very far away, but you'd be surprised how good photos you can get estimating the aim point. The upside is very quick photo missions without messing around with the iPad and app. I do this when I just want to fly over a cliff ledge and get a selfie for example, or get a quick panning video of an area. I suppose another downside is not being warned by the app of compass problems or similar. Been a nice quick way for me to occasionally fly however, without that giant iPad hanging on the transmitter, and just wondered if anyone else did it.
