RE: Hydro airfoil ????z
You need to add weight to both sponsons, but if you have a left side lifting problem, put a little more on the left. Something else to consider is that since the sponsons are hollow, when you put the weight on the inside, more will be in the front than you are presently running on the sponsons. This might let you drop a few ounces from inside the cockpit, but that will take some experimentation
