My Posts This: Topic Forum | I upgraded from a TT53 to the OS55. Not only does the SDX have better performance than it did by a large margin, it has performance as good as my T700 with a YS .91SR. That is saying a lot.
I live at 6,200' and the drop in performance up here is staggering. The SDX with the OS 55 is the first .50 class combination I have seen that can do fast tic tocs, climbing tic tocs, and anything else you want to throw at it without bogging. Like others have said this is without even getting the motor fully leaned out. 
Anybody want to by a TT53 cheap? Really cheap? I am not kidding.
