Convex Figures with Tridrafter Pairs

A tridrafter is a polyform made by joining three drafters, 30°-60°-90° right triangles, at their short legs, long legs, hypotenuses, or half hypotenuses.

A polydrafter is proper if its cells conform to the polyiamond (triangle) grid, and extended if some do not.

Below I show how to make a minimal convex figure using copies of two tridrafters, at least one of each. These solutions are not necessarily unique, nor are their tilings. If you find a solution with fewer tiles, or solve an unsolved case, please write.
