The TT120 would be very good as its performance is about the same as the YS110, both will turn a 16x6 prop at about 10,500 RPM just that the TT120 will do it on 15% fuel. I have both engines. The YS turned an APC 16x6 at 10,000 ROM max whilst the TT120 at 10,500 RPM. However it feels different flying both engines, the YS giving you more torque and making feeling more confortable.
