Hey DZ,

Yep I know...I usually run my YS's on either Model Technics YS blend (20% nitro, 20% techniplate) or Bekra 30% (which has, I think, 21% synthetic mixture of techniplate and EDL whereas the 20% bekra has only 18% synthetic). But I was just making a comparison for my own sanity, so I gave the YS a quick run on the same fuel I'd been putting through the Saito (which was klotz techniplate).

Having said that, the current operators' manual for the YS FZ110-S does recommend 15% to 20% nitro and 15% to 20% synthetic oil, and I know a couple of people running on 15% nitro with no problems at all. Not surprising they are doing this, my LHS has just had to hike the price of YS mix to 31 pounds a UK gallon! That means every flight of my 2m F3A costs over three quid in fuel!!
