So the TT 46 Pros have the same power as the OS 46 FX? My LHS carries the TTs for $70!

FYI: The reason the engine died was because the carburetor fell out. When I got the plane, the motor would not stay running. I found bad O rings on the main needle (fuel spitting out all over) and on the carb base. I used too thick of an O ring on the carb base, which did not give enough "meat" for the retaining bolt to hold, allowing the carb to vibrate and fall out during flight. D'oh! I have since replaced the O ring with high-temp silicone sealant, allowing the carb to seat fully, and giving the retaining bold lots of "bite". I always tune my motors for peak RPM with a tach, then richen them until the RPM drops about 300.
