I will agree with Gray Beard - the DLE is a great engine! I have one mounted in my 1/4 scale Piper PA-25-235 Pawnee from The World Models (review coming soon...) and the DLE pulls the Pawnee around very nicely! All up weight came in at about 21 pounds, and I'm using a Falcon 22x8 beechwood propeller. It's a very nice combination of prop, engine, and airframe!
