Sprink:
I'm using a Norwegian fuel. 15% nitro and 15% Aerosynth Competition oil. This is the same fuel that I use on my helicopters (OS 91 C-Spec), and I've used this fuel on OS 91 FS also.
The glow plug is a OS F plug.

Azhar:
I will check the regulator screw.

Thanks guys!!

ps. the engine is mounted inverted, but I've heard that this is no problem for the YS.
