Guys ive been thinking about using the OS160 (2-strokes) and add smoke system. Im plan to fly classic aerobatics but i would like to have very good vertical climb too. And its not that bad to have extra power even if i need to fly half throttle for scale flight.

At first time i thought it could be to much engine but its a biplane (1,80m / 1,75m wingspans) wich has lots of drag, plus smoke system and wires on the wings for eyecandy.

What do you say?
