RE: Saito 125 Fuel Mix
I only did it as a mistake - the teenagers (12 and 13 at the time) didn't twig to the fact that they were filling the flight box container with a different color fuel to normal and I didn't supervise them properly when they were doing the first fills for the day. I wouldn't recommend it to be done as a normal practice it sure plays havoc with the tuning and the power curve. - Great recommendation for one of our favourite engine brands though - they still ran OK on it.
