I have been very happy with my Thunder Tiger Tiger Bipe 40 ... it's designed for a .35, so a .40 is almost over powered (but fun.) :-) Because it's a bipe and each wing smaller, it can fit in the trunk of my Jetta fully assembled. It flies great ... and after looking at a biplane for a while, monoplanes just look like they are lacking something ... can't quite put my finger on it, but they just don't quite look right. :-)
