I have an LA46 with a Randy Smith NVA in a laser-cut (current) Brodak Vector kit. Stock OS venturi, Randy Smith tube muffler, APC 12.25 x 3.75 cut down to 11.75. Sig 10-10-10 fuel with a little castor added to make it 22% total oil. Thunderbolt RC Long plug. Match made in heaven. Runs a strong 4-cycle through the whole pattern. Plastic Kavan 6-oz clunk tank, quasi uniflow, no muffler pressure. I think you would find this a good setup. You will love this plane and motor combination.
By the way I lived in Edmonton as a child. Mom's from Weyburn Sas, grew up in Regina. Family moved out to the two coasts after one too many -20 winters.
