Both engine have same dimensions. Left engine is made by metal , on the other engine is made by laminated acrylic thin plates. Of course, heat cap was grass.
3mm-acrylic plates are cut using a laser cutting machine, then they bonded each other. Total costs of the acrylic one is cheaper than metric engine/
Even too small engines, they showed 1500rpm over drive.
We'll introduce in some academic conference soon.
good work .
