I installed a new DLE20 RA rear exhaust engine in my old Hanger 9 PT-19 last week and flew it a bunch of times this weekend. The little engine ran like a champ right out of the box. About 20% more power than the Magnum 1.20 4-stroke glow engine it replaced, I would guess. I used a Valley View 17x6 prop and Pennzoil at 32/1 as recommended by Valley View.
I will be using one of these in my new Hanger 9 Tiger Moth in a month or so. This is the perfect engine for narrow cowled planes.
