There seems to be an Attitude among the DA owners that says that if it ain'd DA it is junk. I have tried different kinds of engines, although I must admit not DA, and I think they all have their pro's and Con's. I live at 5300 ft MSL and Density Altitude during the summer averages about 7500 ft MSL. Therefore what works at sea level will not work here!! The evolution 58 is the only engine I have found that is powerful enough to 3D a 18 pound 50 cc Plane. Remember that Weight is a factor. Evolution engines start great and run great. Just a few bugs that need to be worked out
