Does anyone know of the average oz/min the YS-110 and YS-140 Sport does?

It would depend on the nitro content of the fuel used. With 30% heli fuel, the consumption is about 1.5 oz/min on the 110, and almost 2 oz./min on the 140 at full throttle. With 20/20 the numbers are less by about 15%.

Thanks Dave thats what I was looking for.

Good Flying!
