Wanna see a Tiger60 with an OS75AX on it?

Here is mine. It's a great combination. Excellent matchup.

As for any worries about being tail heavy, don't sweat it. The airplane is one of the best low wing trainers ever. It was designed to be an entry model for people learning to fly pattern. It tracks like it is on rails. The only thing I don't like about it (ready for this?) is that it really does not want to tip stall. It's really hard to snap roll the thing because that straight wing isn't going to stall. That also makes landing the sucker a sure bet. You are not going to see one tip stall on approach.

Great airplane.
