Dies your GWS Slow stick just hover in the air if you don´t touch the sticks?
Because I could never ever see out of that distance which way the heli or whatever it was is tilting to compensate that.
Sorry for the late reply! Missed your post until now.
I hope I understood the question, but here goes;
I wouldn't say the SS hovers (unless there is a headwind!). It does get tossed by the breeze so you do have to keep 'flying it' to keep it on track over the target... smooth movements though.
My askman camera mount lets the camera 'hang' so gravity keeps the camera straight while the aircraft moves about. Camera tilt angle is adjusted by a servo. Just don't forget to switch the tilt back up for landing (ask me how I know!).
As for seeing it at a distance; the aircraft is constantly moving so you can tell where its going by where its been. For example if its flying from right to left in front of you and moving away at the same time the right wing is down and its slowly turning right. This might need left rudder compensation if you need the aircraft closer to the subject.
Question answered?
Another photo to keep the thread interesting:
This is Pretty Beach on the NSW coast (Australia). I'm standing in the front yard of a house we were staying at (with a green roof to the top left). The road was the runway (no traffic there!).
