Roughly half and half red Morgan heli fuel (NOT the "low smoke" type) 30 % nitro/23% oil. To straight methanol, adding 4oz T Plate. Gives me easy starts, easy storage and long bearing life year round cold and hot. Works from singles to 3, 5 7 Cyl radials. All comes from local sources at 2/3 the cost of pre mixed over the counter containers roughly.
Nice contrails ta boot. Works fur me.
