Hyperion 25e Piper Cub Questions.

First of all I really haven't seen much on this plane but did see a post regarding not thinking the Power 15 would be enough motor. That has me totally confused as the plane according to the MFG weighs max of 48oz with the recommended motor that as near as I can tell by the Hyperion Specs produces less watts than my Power 10 which MFG says produces 323W with a 11 X 5.5 E prop and 357W with 12 X 6 E Prop. Some quick calcs based on those figures indicates the Power 10 would give me 108W/lb with the 11 X 5.5 and 119W/lb with the 12 X 6 figuring a AUW of 48oz. Hardly a underpowered Piper Cub. Am I missing something here or just why would you need more power than the Power 10 I am thinking of using???? Would like any comments from someone now flying the plane with the recommended or what ever motor as to flight performance and flight characteristics before I order. Thanks.....
