Yeah the only thing I hate about glow powered engines is the clean-up. Gasoline powered planes are typically cleaner, but vibrate considerably more in many instances. It comes down to personal preference. This is an expensive hobby and the most bang for your buck is an appealing selling profile for me. If I can live with the DLE and afford say better servo's or retracts or whatever, then I am down with it. And after all, does a 4 stroke really sound like a radial anyway? Only a radial sounds like a radial. So now we are talking a MOKI? OMG!! It really is a personal preference it is the modelers choice.
