RE: GP Super Stearman Gas vs. Nitro in cold climates?
I have a Supper Stearman with a Saito 1.80, stock tank . I have the timer set for 10 min. and try to have wheels on ground when the buzzer goes off, not much left. Pulls the Stearman around with authority!! Just a thirsty little bugger. I use 15% fuel.
