Oh I forgot to say mine powered a 88 inch wing span 16 pound plane marginally OK for scale like flight but not a lot of power in reserve. You might want to look into this engine, my friend imports them, they are better than the SPE26. I'm flying two planes now with them, a Celmark S2 pitts, and a 67 inch Yak54, really a nice engine.
The picture below is after I coverted the plane to a differnt engine.
