RE: Cool Power for YS
Hi I am waiting now for my first YS engine, shoild be here next week. After reading up on them I realise I am going to have to brew my own fuel. Getting anything here where I live is hopeless at best and costly to boot. you talk about cool power 30% heli, is that blended with a particular oil, and if so what oil? The engine is a YS91FZ, N.I.B and will be fitted to a 55in Ultimate biplane. Any advise will be greatly appreciated
