The question still remains as to what damage it could do to R/C our engines and why DA and BME don't like it, I would like to know how it hurts our engines as DA claims but does not hurt full scale aircraft engines. It would not change performance signifigantly and I don't see how it can cause engine damage to two stroke engines.

It stores much better, does not smell nearly as bad and does not form varnish like auto gas can do, it also is cleaner fuel as far as unwanted water etc. Some claim it does not produce as much power but I doubt it makes enough difference to notice.
