I bought the Slipstream 30cc Sbach with the DLE 30cc motor as a package only to find out the plane will not accomadate the 30cc motor without severe modification. Further it was so lightly constructed I doubt it would have survived. I sold it to a buddy who electrified it and it is great. The radio and 30cc motor now reside in a Pilot Sbach and it is a good flier. The Pilot airplane is designed from the ground up for the gas motor. After all is said and done I really wish I had bought an Aero-Works though.
