Did you know that the Peking Boulevard’s variable geometry biplane wings sweep in opposite directions?

The top one goes forward whilst the bottom one goes backwards? This helps to preserve the location of center of lift.

Update:

@ Bertsta. Who told you the Peking Boulevard had rigid interplane struts?

It has articulating and extendible interplane struts that uses jack screws. The jackscrews are actually what set the lower wing sweep in relation to the upper one, so it does not need an independent swing sweep mechanism.

    This dumb wing configuration was what cause the Peking Boulevard to be destroyed. When the wings moved counter to each other, it tore out the rigid interplane struts, and lacking adequate alternative bracing, the wings folded up and the plane crashed into the sea, killing all aboard. If you are a fan of the obscure I suggest you research the Shanghai Surprise. You are def going to enjoy that one.
