Just a thought after reading the "crash" comments.
It is possible to turn back after engine failure but you need a height / speed window to achieve it. bck in the days when I was a QFI on Jet Provosts in the RAF as I recall we had a window to turn back when higher than 400 ft and 180 kts, we used to practice but it was pretty hairy, the essence being to get the nose down and turn into any cross wind immediatly and then monitor speed very closely as you manoeuvered for landing. The other option being to eject!
I guess to turn back a low energy aircraft like a Kitfox, the same principles apply the vital one being to get the nose down to preserve speed, and to turn into any crosswind. Practice at height from a high nose climbing attitude and see just how much height is lost with a simulated engine failure and turning through 180 deg. Then add say 25% for a safety margin and that would be your minimum height for turn back. Never even think about it if you are below that height.
Of course other factors come in, like landing down wind can give you a false visual illusion of speed, so monitoring airspeed is essential, and you are much more likely to ground loop on landing with a significant tail wind.
The safest option is of course to land in that big field straight ahead, but sometimes its not there, still better to control the crash into wind than to stall in down wind!
