Expansion chambers for an airplane!?

Cricri featured

When I got a call to make a set of expansion chambers for “The world’s smallest manned twin engine airplane” I just could not resist!

The Colomban Cri-cri (or Cricket) was designed in the early 1970’s by Michel Colomban. Since then many renditions have been built.
