I tried a TT120re for a while. The engine was very strong when it ran, but a tuning nightmare from one flying session to the next. Be sure to clean the fuel pump per TT instuctions after every flying session or you'll have trouble. The bearings that came in my engine were not good either, as I had to replace them right away. Mine was set up with the MAC system which came with the engine. I ran a 16x12 APC with 15% powermaster.
