The TwinStar is a good little airplane. I had one and flew it on land and on floats. It's an easy flying twin, very forgiving and easy to control, take off and land.

The TwinStar has, in my opinion, 2 glaring problems: 1. The tanks are only 4 ounces, maybe less. There ain't no way to fit bigger ones short of lengthening the nacelles out front. 2. The trim and then the covering peels off. Iron it down, clear epoxy it down, CA it down, but keep at it. I lost most all my trim and recovered the wings.

I used GMS .32s on land and Thunder Tiger GP .42s on floats.

As I recall, the TwinStar comes with the Great Planes 20-48 sized engine mount. It might spread enough for the .52s. I ended up cutting the cheeks off for water use with the larger engines.
