Variable Pitch EDF, she canny take it any more captain...

Some test pieces for a project I've been working on, a variable pitch EDF fan unit based on a 450 class helicopter head...

All was working well intill I got over enthusiastic with the speed control... the head is speced to 3000RPM, I got to 9000 and unfortunately the swash alignment link broke probably due to bearig drag and blade loads, and well you can guess what happened next :-)

Anyway the principle is OK, hopefully just needs some bespoke machined links to make it work.

Onward...
