As I've mentioned a few times, here, there and other places, I use the large bright yellow reel for the release cord. And, I locate the launch "base" several feet outside the flying circle. So, at launch, the model is well outside the flying area.
I have, usually, a large nail (in turf) or a weight - like a claw hammer, to locate where the reel winds up. Start, pin the model into the release device, walk the line out to the handle - making sure it is clear of the flying lines!
Pull, stand up, step back the few feet needed, and do your flight. Try to land with your feet near the nail or weight. Hang the handle on the marker, walk the lines to the model, then back to untwist them. Walk the model back to the launch point. It should all line up for the next flight if you do it this way.
The cord is leftover Hi-start line from when I as doing that, too. Anything strong enough to release your tie-down is good enough. When done for the day, I reel the release line back to the 'launch pad' - a piece of iron 1/8" about 2 x 2.5' - and hang the reel on it.
Takes some precautions, and attention to detail, but that comes naturally very quickly.
