Id say the Suxxess is not so much an inconclusive design as it is not whole heartedly suitable to current F3a schedules in all conditions.

F3a has certainly moved inthe direction of Biplane benefits in recent years but as we all know they (at this size) are more susseptable (spelling !?) to cross winds etc and whilst they perform some manouvres better than monoplanes, others they fall down on.

At the moment F3a is not completely Bipe friendly (for the top guys) and I doubt it ever will be.... at least not with the EP situation.... I thin this will be the next revolution...and I dare say within 5 years will bare some influence over the f3a comp itself..
