av8tor1977,, know what I'm thinking for my 44cc Super Tartan Twin,,

because the Tartan is a Straight Methanol Engine and has such a High Compression Ratio>, take 1 Gallon of 5% nitro, increase the Oli Content to 20%, then mix it Half/and Half with Gasoline, go fly,,

this will be very simple and give me 2.5% Nitro with 10% oil, Burn less fuel and drop my fuel pricing Per-Gallon

on the other hand I'm thinking maybe just getting it over with and convert it to Ignition, BUT that will increase weight and that is one thing I dodn't want to do to this plane, it weighs about 15&1/2 pounds with the MVVS 35cc Gasser and with the Tartan (Igition) it will be about 16 Pounds
