I just bought a plane with a Super Tigre S 3000. Supposedly, 0% nitro and 12% castor is the preferred fuel for these engines. Are you saying that all I need to do is buy some Sig castor, and a gallon of VP racing methanol, shake it up and I have fuel??? That's awesome because a gallon of methanol is $5 at the drag strip.
Yes thats the norm in Castor or replace with typically 10% in high quality EDL synthetic but dont run lean or 8% in high quality EDL synthetic and 3% Castor for the mechanically challenged at tuning that might run it lean giving them a little head room protection
High compression motors like supertigre and MVVS all can run happily with zero nitro
$5 a gallon of methanol lucky you I pay in LHS ~$13 a USA gallon just for methanol neat and oil costs are on top of that
