My 120 is setup with flaperons. Makes for very interesting high AOA maneuvers. Only reason I did it was to slow that beast down to land it. The DLE 20 is not reliable enough runs different every time I start it so I gave up flying it and it just hangs in my trailer collecting dust. I should weigh the DLE and compare it to the FG-30. Would be interesting to see how it flies with the 30 on it's nose. Now to go and make a battery harness for the OBG and wire up the GP so I can get this engine running.
