Dimensions are OD and in millimeters? What is the material thickness?

I used mild sht. mtl. approx. 20ga. & I found a oil filler tube at a small engine shop, as my intake,it already had the bend&a start on the flair, win win lol, it would be way better to use 22ga stainless though,because she's wearing out quickly"

Very nice build!

I also squeezed the intake where it meets the body,to a elliptical or ovel shape.

I've found it is fairly easy to make the body sections out of paper 1st, & mock up the entire body in paper,than you can cut the sections open&trace them on your metal.

Have you tested the amount of thrust?
I am very interested to compare our engines, I made a FWE that is a very similar size.

I haven't measured the thrust, but all I know is she's a animal! & stuff that didn't blow of my shelves with other PJs. The hpx blew off my shelves all over the garage! Or standing behind it & getting blown in the chest, it felt powerful&the air blast is surprizingly cool temp. Very interesting" I really feel it could fly a rc plane, just need to get liquid fuels to work on it! I need help figureing that out!?!? A valveless rc plane would be the bees knees!!!! Lol
