Interesting question. They look almost identical and they weigh just the same. They are strong little runners just like the DLE. You can expect the same quality as the DLE if not better I think, consideriing the walbro carb, rcexel ignition with proper advance curve, etc. Definitely a steal at that price. Frank Bowman has rings for them now too. Tom put one on the test stand, wide open throttle, and left for an hour or so. When he came back it was still happily screaming away. I won't have mine going until next spring in a ProX260 profile plane.
