I will suck it up and maby try a glow engine on a pylon .I got a 80 mm  Delta 32 EDF out of a Habu  The brochure says  in a static lab test it puts out 5.4 pounds of thrust and a lab test in a Habu 4.8 pounds of thrust . I don't plan on zipping all over the sky like the guys with the jets do even though I will be the same weight . My plane has a very efficient high lift high aspect ratio air foil it…
