ORIGINAL: highside

I've just dropped a YS FZ1.10S onto the test-bench, same fuel (15% nitro, 20% klotz)...

HighSide,

The YS is very likely to run badly on that fuel...

Unlike OS (and its clones) and Saito engine, that will run nicely on fuels containing 15% nitro (or even less), YS engine require 20% nitro as a minimum, to run as intended.

They are designed for high nitro percentages, rather than this being a convenient option...

Also, are you talking about Klotz Techniplate?... Knotz BéNOL castor oil is not the ideal oil for a YS. 2% of this oil is OK, but not all castor, if you want to keep your maintenance to a reasonable frequency...

On 15% nitro these engines may need to be leaned down excessively, to the point of overheating, just to get the proper mixture strength.

I believe the YS 1.40 Sport is their only engine for which 15% nitro is within the recommended percentage...

Testing your 1.10 on that fuel will prove no point.
