I have a TT.46Pro in a Goldberg Tiger, kit-built. It's a great engine and runs flawlessly. It has more power than I need and I usually fly at 1/2 to 3/4 throttle. I had had one a couple of years ago in a Pilatus Porter that really needed a .60. With an 11X6 prop it flew it very well and I really enjoyed it.

I recently purchased a World Models T-34 Mentor with a brand new Super Tiger .40 installed. This is one of the Italian ones, not the Chinese. It will be flying soon as it needs the control runs installed and a radio.
