I used to have a lot of control line planes and a gaggle of Fox 35's, OS MAX S-35's, Super Tiger G21-46's, etc.
I sold them all except the ST's to one guy. There were two Magicians with OS S-35's. He stuck a LA40 with muffler on one and took both planes to the CL field. The one with the LA 40/muffler was much more powerful than the S-35 powered one which had no muffler. I was really surprised.
