I fly a profile with a saito.91 (top cap) and the 4-stroke torque is amazing

I have a 3.5 pound home built stick I put a saito .56 on again the torque of the bigger props makes em a joy to fly. The throttle responce is instananeous (sp?) the fuel economy much better.
The sound is much friendlier. I had a TT pro 46 on the stick before I put the saito on,I hardly ever flew it. With the saito it is turning into my everyday flier. The saito out performs the TT by a good margin. and idles ever so slow. All my 2 strokes are goin down the road. I much prefer the 4 strokes.
Give one a try..... you will see what I mean.
