160 SX
I had a 160 in mine for the first twenty flights, then i sent it in and while it was serviced i used a 120SX. Didnt really notice that much difference in all out speed. Takeoffs were a little shorter, but i was surprised at how little difference it really made.
While i had the 160, my friend had his 120, and people watching could not substantiate which was faster. Both are fun, is the bottom line. Enjoy.
