The 32 to 1 is just fine. I use Husky or Stihl Syn. oils in all my engines with NO problems. I use the same oils in my chainsaws @ 50 to 1 the called for mix for them. In my opinion the saws work much harder than an RC engine in most cases!
Modern saws are surrounded by a case that requires a cooling system.........usually as much or more than a tightly cowled RC engine, overload either and you will have issues , heat.
In my opinion there is no gain in too much oil, just more mess to clean up.
