RE: prop help
Don't be afraid to try different props a wide prop doesn't mean better 3d any prop that lets your engine run like it needs to while giving enough thrust will work fine
I have a 52 magnum 4 stroke that can't turn a 13x4w but turns the 13x4 sport just fine but can't turn a zinger 13x4 it just bite muchs harder then the 13x4apc sport
