It's all about personal preference and flying style to decide which would be best for your Saito 1.50, but if I had that engine on my bench(and I don't, but wish I did), I would like to have a Hangar 9 Super Cub ARF. A slow fly by with that Mello Sounding Saito onboard would be shear delight! I have a 4 stroke Magnum which I think sounds pretty nice until someone at the field fires their Saito up. Kind of like a Honda next to a Harley. Both run nice, but nothing can compare to the sound of a Hog.
