The blue fuel is no good..
I had a little talk with one of the RC veterans who has been in this hobby for 30+ years.
He used to be part of the Mugen company and have extensive experience in designing and modifying nitro engines.
I don't know why he hates the blue fuel.
He is using Tornado fuel which is really expensive and urge me to stop using the blue fuel. Either get the red fuel or something better.
Any thoughts.
