Today I tried to start my new OS.46FX-H engine installed in an X-Cell 30 heli. However, as soon as it starts and I advance the throttle a bit, the engine dies. I've tried setting the needle valve at everything from 1.5 to 3 turns open, and nothing helps.
I was wondering if the problem might be the fuel, or rather the oil. I'm using 5% Nitro and 18% Aerosynth oil.
I had the exact same problem with my former engine (same brand and size), until I had to buy the new one because it had rusted (I forgot to put after-run oil in it). However, I did get this engine to run (though it often quit in mid-flight), by running it very lean.
I hope someone can help, as I'm getting pretty frustrated by this!

Thanks
