The 180 turn can be a problem, even in a fixed wing - My SAR crew and I were called out one day to look for a a missing Cessna with 3 on board which had departed Swansea and was heading through the Welsh hills to Halfpenny Green ISTR.
We tracked a 121.5 beacon up the Neath valley underneath the cloudbase and realised the signal was in or above the cloud so we followed it upslope in the gloop (hovertaxiing) and got a sufficient increase in visibility at the top to see a wood with 3 guys at the edge of it.
After landing on to let the winch op question them, it turned out they were the ones we were looking for and their Cessna was parked 45 degrees nose down in the middle of the wood.
If the pilot had executed a good 180, they would have smashed into the hillside - instead he pulled back on the stick, washed off the speed but gained enough altitude that when the aircraft stalled, they were about 20' from the top of the wood and it plopped in - no injuries.
Apologies as I have recounted this tale before but it seems pertinent here.
