NECESSARY ACCESSORIES The following items are necessary for operating the engine, these are available at you hobby dealer. FUEL A good quality, commercially available fuel containing 25% lubricant and 75% methanol is recommended for break-in/run-in and general usage. We also recommend castor oil or a castor/synthetic blend only for use as a lubricant. Fuel containing 10%-30% nitromethane and 20% lubricant is for use when more power is required. Most fuels containing synthetic lubricants (only) are much less tolerant of a lean run compared to fuel that contains castor oil. If availability or local conditions force you to use a fuel that contains only synthetic lubricant, we suggest that you keep your needle valve set to a slightly richer setting, allowing more lubricant to flow through your engine to extend engine life and maintain optimum reliability. Do not use fuel containing less than 20% lubricant.

Infatti mi sembra eccessivo anche a me, anche se con i 4t aeronautici vado di 18% di olio come tutti.
Ho dato una letta ai listini di jonathan e giannimodellismo e nessuna riporta miscele già pronte con una percentuale maggiore del 10%.

Perché non esistono infatti...il 20% di olio è tantissimo per un motore del genere. Vai tranquillo con il 10%
