i dont own the DLE30, but some of my friends does...in AW yak and Pilot RC airframes, i have a DLE55 but i like to read, learn from people and field test, and i can tell you that the DLE and MT will be really good option for you, dont forget to get it from someone that will offer great service after you bought an engine, so Valley View RC with Jody is a good way to go.

If you really want something to make your airplane hover, pull out with ulimited vertical and let you get out of trouble, those engines are your choice with a 18x8 or 19x8 propeller.
