Sig Kavalier Engine Selection
Mglowe, I own a kavalier which I previously installed an old .40 Italian made Supertigre, and flies fine, I believe the .35 should be ok. But if you can handle well a trainer, do as i did, Build the wing straight ,( cero degree dihedral) and install a TT.46 .
You are going to love it, very aerobatic and sturdy plane, but forgiving at slow speed and landings.
