hello I’m new here and I just want to show my EDF AfterBurner inspired by David’s vampire back in 2013. This model is called “EX-6a” and it was built to explore what is an afterburner and how to build one. After learning from EX-6a and don’t using foam for the ducts. I’m going to build EX-6b with a flame holder. and the goal of the EX-6 is to build a true micro jet.
