,Hi Downunder,
I agree,
A close friend has been flying for more then 30 years.
He seems to know how to get max efficiency from the engine without NITRO.
I use 5% and just ordered 8 gallons.
I use it because the manufacture says use 10% with the OS 40.
I flew the other day when temps got to 50+ and noticed no difference so I guess 0% nitro will work as well
