As far as I know, Christophe is still developing Suxess, Chip's is the finished article. I am going to play with Madness then get my Caprise out. A biplane would be for me too tricky and too costly to set up. (I mean the base kit prices are high - the finished product = £7,000.00s) . At this stage, it's way to early to comment on the biplanes, but from the impressions of some people, many top fliers still feel the best potential comes from a monoplane.
