How could it run hotter on 10% compared to 15% or 20%? 10% nitro content is less nitro than 15% or 20%. That doesn't make any sense to me. I'm conservative running 10% in my model airplanes when a lot of the guys around me are running 15%. CONTENT: Nitro 10%, Oil 18% (80% synthetic, 20% racing castor). I must be missing something completely. I'll check the content on the O'donnell or Sidewinder

If you can clear this up for me, I'd appreciate it.
