Aeromaster and Sportmaster shared the same canopy.

I've cut that same canopy down and it fits the Trainermaster too.
I cut one down further and it fit the Minimaster.

That's the good news, the bad news is Great Planes discontinued the canopy.

If you find a source for them please let us know. I need a couple more.

John, the red one was two different Sportmasters, I recycle.
