Hey mate
I'll suggest you sould use a "premix only" kind of 2stroke oil for the rc engine family.Like u said,lots of oils out there but not all of them for premix usage.For example , motorbike and/or marine outboard engines keep the 2stroke oil in a separate tank and they're equipped with an oil pump in order to feed the carb/injection.This kind of 2stroke oil isn't designed to be premixed with the gas therefore it might be a risk using this on RC engine
