When landing the Ta152, you just need to use flaps and put it down slow enough that it stays on the ground when you pull up to fixate the tailwheel. Voila, no ground looping. You could force it down by taking in the flaps a notch, or take them in as you set it down to make sure it stays down. Why so many people have problems landing it I have no idea, perhaps because they use autotrim or stall limiter?
I use auto-trim, it's not that.
It seems that people seem to have trouble getting the tail down and keeping it down.
Or perhaps they are impatient and try to land too fast. Fast landings in the 152 increase the possibility of a ground loop in the 152, I find. The slower you are when the gear touches the ground, the less aggressive it is if you let the tail go and find the nose starting to hunt across the runway.
Flaps, flaps, flaps, just above stall, nice and gentle. That's the key.
For those who struggle, get full flaps out, gear down and aim for the start of the runway. Get as low as you can without touching down and maintain level flight just above the runway. If you can manage that nicely just ease throttle off and increase you elevator input in accordance with throttle... like the clutch and accelerator just after a gear change in a car. If you get that right, you won't even bounce when you touch down and as you're already pulling back on the stick, the tail wheel should already be locked.
