I had compared notes with a gentlmen and his son who also brought a Prodij to temple hill last weekend and they had the CG moved back a little while having no nose lead at all. Their setup didnt have any aileron differential so their rolls were much faster and their plane seemed to be a little more agile with the conditions. I think I'm going to remove much of the differential and continue with some stick time on it before I try before I start adding ballast and see what this baby can do.
