If bigger is better, smaller may be boss.

I went to my r/c club flying field and found it usable for control line planes. I fired up the Ringmaster and it didn't run too well. I got a couple short flights in and concluded the .40 was too powerful. Mid 4 sec. laps. I flew the Twister and made a leadout location adjustment. I think it needs another adjustment but I'll fly it first to see. When I got home I removed the .40 and
installed a Fox .29. It has the same mounting bolt pattern as the .35. I had to fit a muffler to it and that took an hour as it isn't made to use one. An O.S. .25 r/c muffler works fine on it. Maybe I'll get in some more flights in the morning before the temp. gets too high.
