My YS 80 is on the way , want kinda flying time can I exspect to get with a 16 oz tank ?

I get around 12 min with 20oz now but for the first few flights when it was really rich it was about 10. Thats flying hard and not too many autos or hovering.

I get on the average of about 14 mins with 8.18 gear ratio and 18 ozs of fuel. I am using low viscosity oil fuel at 14% content so I have the needles only open about 1 1/4 on the hover needle and 1/2 on the high needle.

How much nitro?

For practicing and everyday flying I am using 20% nitro 14% LV oil. For contests I an using 30% nitro 14% LV oil. The less oil and the low viscosity allows the motor to run better. RC car racers have known this for years, that is why they only use fuel that has 8 to 10% oil on the average. Those engines are turning in the 30K rpm range and it a lot worse environment than a heli.
