Mixing different brands of fuel ?
I have 15% green of one manufacturer and 12% red of another and I want to mix them. I am guessing if I mix equal volumes, I will obtain 13.5% fuel. Is there anything wrong in dong this ?

Other than ending up with a strange color fuel, no. However, any time you change fuel, be prepared to re-set your carburetor.The government cannot give you anything without first taking it from someone else.

Don't do it.
There's a high probability, that both manufacturers use different sorts of oil, which could have a negative impact on each other, leaving the engine without sufficient lubrication.

If you want to switch brands, just use all of one brand, leave nothing of the old brand in the tank or in a canister, then switch to the new brand.
Be prepared to change the glow plug directly or shortly after.
And have an eye on the carb settings.

Why the glow plug?
I have no reason for it, just pure experience.
Over the last 10 years or so I used about 4 different fuel brands.
Anytime I switched brands, the glow plugs of all helis failed after one to three tanks.

I wouldnt mix the fuels. You can use one after the other but I'd be concerned about incompatible ingredients, especially the lubrication packages.

Well I did mix some 10% green plank fuel that my helis nver ran good on with some 30% CY heli fuel that was sitting around. It came out a nasty green color and I never tried running it in a heli after that, but I did run it in a cheep nitro car of mine. I had no porblems with the plug or the motor. Both are still in the car.

would I trust it in my nitro bird?

No.Fear is the little death,The mind killer. I will allow my fear to pass through me.Only I will remain
