I too have herd and read several threads about running heli fuel. Perhaps those that aren't broken in correctly need to run the eli fuel?
Perhaps doi to the porting and temp requirments for the large of an engine, the heli fuel keeps it at the right temp..
I always try to comapre things. Just as for 1/1 cars little four cylinders seem to run hot very hot, and if forced to run cool performance will suffer Their larger cousins run much cooler for performance and longevity
Perhaps the size of the engine and it's cooling charachteristics account for the problems, and the heli fuel. If yu do have tunning problems after break I would definetaly suggest the fuel
