Hi everyone, Lets say your flying at or about sea level using a 5% nitro fuel, What percentage of nitro would it take to achieve the same performance level at 3,000 feet. BTW Im using a fox 35 stunt. Thanks, Paul

Personally I prefer 70% Nitro when I fly. (Not Stunt) and I don't think your Fox will tolerate that.

Now Bill,

You fly stunt too. Probably 15% for the Fox .35 at 3,000 feet would give it adequate performance, maybe even a slight boost.

I think you ought to run 15% nitro at sea level - I'm not kidding! It's not like it's overcompressed.

The answer to the original question is to add nitro until you get the same fuel consumption at altitude that you do at sea level. If you don't have sea level data, just add nitro until the break gets excessive, or more likely, you can't afford to buy it anymore.
