RE: 28% edge w/ brisson 3.2
With what you desire, I don't think either the DA or the Brison will suit your needs unless the plane stays under 16 pounds, which is not likely regardless of weight saving technoques. Both will easily pull the plane up out a hover while accelerating, but the acceleration will not be overly aggresive. You may want to consider the MVVS 58 or possibly something in the 60cc range.
