RE: Sig Sundancer 50 ARF
I think that I will use the Saito 82. I have one in my pattern plane and I love it. Once I broke her in and set low end, I have never had to touch it. I have a OS 55ax in my FourStar. It is a great engine, but doesn't come close to the Saito 82, but the Saito does cost about 100 bucks more!!
