Its a very rare model engine of any kind that even comes close to sounding like its full scale brother. With that in mind, I prefer an engine that is reliable and produces the kind of power I need using a prop size that works well with a particular airframe. These days, 2 stroke gassers come closest to filling that requirement.

4 stroke gassers may one day fill my requirements but I have not yet seen one that is truly reliable yet still affordable. I don't miss the larger, fuel thirsty, 4 stroke glo engines I have sold.

Regarding the OP's requirements, I agree with those who suggested the DLE35.
